System Log Types

There are five types of logs that can be configured and viewed on the system:


Important

Not all Event Logs can be configured on all products. Configurability depends on the hardware platform and licenses in use.

  • Event: Event logging can be used to determine system status and capture important information pertaining to protocols and tasks in use by the system. This is a global function that will be applied to all contexts, sessions, and processes.

  • Active: Active logs are operator configurable on a CLI instance-by-CLI instance basis. Active logs that are configured by an administrative user in one CLI instance cannot be viewed by an administrative user in a different CLI instance. Each active log can be configured with filter and display properties that are independent of those configured globally for the system. Active logs are displayed in real time as events are generated.

  • Trace: Trace logging can be used to quickly isolate issues that may arise for a particular connected subscriber session. Traces can be taken for a specific call identification (callid) number, IP address, mobile station identification (MSID) number, or username.

  • Monitor: Monitor logging records all activity associated with a particular session. This functionality is available in order to comply with law enforcement agency requirements for monitoring capabilities of particular subscribers. Monitors can be performed based on a subscriber's MSID or username.

  • Crash: Crash logging stores useful information pertaining to system software crashes. This information is useful in determining the cause of the crash.


Important
Stateful Firewall and NAT supports logging of various messages on screen if logging is enabled for firewall. These logs provide detailed messages at various levels, like critical, error, warning, and debug. Stateful Firewall and NAT attack logs also provide information on the source IP address, destination IP address, protocol, or attack type for any packet dropped due to an attack and are also sent to a syslog server if configured in the system. For more information on logging support for Stateful Firewall and NAT, see the Logging Support chapter of PSF Administration Guide or NAT Administration Guide.

Configuring Event Logging Parameters

The system can be configured to generate logs based on user-defined filters. The filters specify the facilities (system tasks or protocols) that the system is to monitor and severity levels at which to trigger the generation of the event entries.

Event logs are stored in system memory and can be viewed via the CLI. There are two memory buffers that store event logging information. The first buffer stores the active log information. The second buffer stores inactive logging information. The inactive buffer is used as a temporary repository to allow you to view logs without having data be overwritten. Logs are copied to the inactive buffer only through manual intervention.

Each buffer can store up to 50,000 events. Once these buffers reach their capacity, the oldest information is removed to make room for the newest.

To prevent the loss of log data, the system can be configured to transmit logs to a syslog server over a network interface.

Configuring Event Log Filters

You can filter the contents of event logs at the Exec mode and Global Configuration mode levels.

Exec Mode Filtering

These commands allow you to limit the amount of data contained in logs without changing global logging parameters.

Follow the examples below to filter logs via Exec mode commands.

Active Filtering
logging active [ copy runtime filters ] [ event-verbosity event_level ] [ pdu-data format ] [ pdu-verbosity pdu_level ]

Notes:

  • copy runtime filters   – Copies the runtime filters and uses that copy to filter the current logging session.

  • event-verbosity event_level – Specifies the level of verboseness to use in logging of events as one of:

    • min – Displays minimal information about the event. Information includes event name, facility, event ID, severity level, date, and time.

    • concise – Displays detailed information about the event, but does not provide the event source within the system.

    • full – Displays detailed information about event, including source information, identifying where within the system the event was generated.

  • pdu-data format – Specifies output format for packet data units when logged as one of:

    • none – raw format (unformatted).

    • hex – hexadecimal format

    • hex-ascii – hexadecimal and ASCII similar to a main-frame dump

  • pdu-verbosity pdu_level – Specifies the level of verboseness to use in logging of packet data units as an integer from 1 through 5, where 5 is the most detailed.

Disable or Enable Filtering by Instance(s)
logging filter active facility facility level severity_level [ critical-info | no-critical-info ] 
logging filter { disable | enable } facility facility { all | instance instance_number }

Notes:

  • active – Indicates that only active processes are to have logging options set.

  • disable – Disables logging for a specific instance or all instances. This keyword is only supported for aaamgr, hamgr and sessmgr facilities.

  • enable – Enables logging for a specific instance or all instances. This keyword is only supported for aaamgr, hamgr and sessmgr facilities. By default logging is enabled for all instances of aaamgr, hamgr and sessmgr.

  • facility facility and level severity_level – Configure the logging filter that determines which system facilities should be logged and at what levels.

  • all | instance instance_number – Specifies whether logging will be disabled or enabled for all instances or a specific instance of aaamgr, hamgr or sessmgr. Run the show session subsystem facility facility command to identify specific instance numbers.


    Note

    These keywords are only supported with the disable and enable keywords.

  • level severity_level – Specifies the level of information to be logged from the following list which is ordered from highest to lowest:

    • critical - display critical events

    • error - display error events and all events with a higher severity level

    • warning - display warning events and all events with a higher severity level

    • unusual - display unusual events and all events with a higher severity level

    • info - display info events and all events with a higher severity level

    • trace - display trace events and all events with a higher severity level

    • debug - display all events


    Note

    This keyword is only supported in conjunction with the active keyword.

  • critical-info – Specifies that events with a category attribute of critical information are to be displayed. Examples of these types of events can be seen at bootup when system processes and tasks are being initiated. This is the default setting.

    no-critical-info – Specifies that events with a category attribute of critical information are not to be displayed.


    Note

    These keywords are only supported in conjunction with the active keyword.


Important

To enable logging of a single instance of a facility, you must first disable all instances of the facility (logging filter disable facility facility all) and then enable logging of the specific instance (logging filter enable facility facility instance instance_number. To restore default behavior you must re-enable logging of all instances (logging filter enable facility facility all).

You can display the instance numbers for enabled instances per facility using the Exec mode show instance-logging command.

Global Configuration Mode Filtering

You can filter the contents of event logs at the Exec mode and Global Configuration mode levels.

Follow the example below to configure run time event logging parameters for the system: 

configure 
   logging filter runtime facility facility level report_level 
   logging display { event-verbosity | pdu-data | pdu-verbosity } 
   end

Notes:

  • facility facility and level severity_level – Configure the logging filter that determines which system facilities should be logged and at what levels.

  • Repeat for every facility that you would like to log.

  • Optional: Configure event ID restrictions by adding the logging disable eventid command. The system provides the ability to restrict the sending of a specific event ID or a range of event IDs to minimize the amount of data logged to that which is most useful. Repeat to disable logging for additional event IDs or event ID ranges.

  • If an administrator restricts event logging for an Event ID or Event ID range using the above command (logging disable eventid ), the system will generate a Critical Event log "cli 30999 critical" as well as an SNMP trap "1361 (DisabledEventIDs)" with the specific Event IDs or Event ID range that was disabled.

    These event logs and traps are enabled by default in this release, and cannot be disabled.

  • If an administrator lowers the logging level (using the logging filter runtime facility facility level report_level command below the default level of "error", the system will generate a Critical Event log "cli 30998 critical" as well as an SNMP trap "1362 (LogLevelChanged)" with the specific Event IDs or Event ID range that was disabled.

    These event logs and traps are enabled by default in this release, and cannot be disabled.

The following examples show the CLI output of the traps generated when event logging or logging levels are changed.

Configuring Syslog Servers

Syslog Architecture

System Logging (syslog) is the architecture which produces and sends event information from the UPF over the UDP transport layer to a centralized Event Message Collector. Syslog uses a client/server architecture:

  • Syslog Client: A set of processes running on UPF, which operate as the sending device for event messages.

  • Syslog Server: An external server configured to receive the event messages sent from the UPF.

UPF transports event messages using the Syslog Protocol without expecting acknowledgment of receipt. The system forwards event messages regardless if a Syslog Server is available to receive the messages.

Configuring the System to Sent Event Messages to an External Syslog Server

Information that is generated by the run time event logging filters can be transmitted to a syslog server for permanent storage.


Important

The data transmitted to the Syslog server is meant to be used for informational purposes. Functions such as billing and performance monitoring should not be based on syslogs.


Important

Although the system provides the flexibility to configure syslog servers on a context-by-context basis, it is recommended that all servers be configured in the local context in order to isolate the log traffic from the network traffic.

Use the following example to configure syslog servers: 

configure 
   context  context_name 
logging syslog ip_address  [ event-verbosity { min | concise | full } | facility facilities |   msg-format { rfc3164 | rfc5424 }  | pdu-data { none | hex | hex-ascii } | pdu-verbosity pdu_level |   port number  |   rate value ] 
      end

NOTES:

  • syslog ip_address : Specifies the IP address of a system log server on the network in IPv4 dotted-decimal or IPv6 colon-separated-hexadecimal notation.

  • event-verbosity { min | concise | full } : Specifies the level of detail to use in logging of events. Detail level must be one of the following:

    • min : Displays minimal detail.

    • concise : Displays summary detail.

    • full : Displays full detail.

  • facility facilities : Specifies the local facility for which the system logging server's logging options are applied. Local facility must be one of the following:

    • local0 —Pertains to syslog severity level of 0, Emergency

    • local1 —Pertains to syslog severity level of 1, Alert

    • local2 —Pertains to syslog severity level of 2, Critical

    • local3 —Pertains to syslog severity level of 3, Error

    • local4 —Pertains to syslog severity level of 4, Warning

    • local5 —Pertains to syslog severity level of 5, Notice

    • local6 —Pertains to syslog severity level of 6, Informational

    • local7 —Pertains to syslog severity level of 7, Debug

    Default: local7

    If local facility is not specified, then local7 is applied by default.

    Multiple system log servers can share the logging options of a given local facility. This allows for the logical grouping of system log servers and the options which affect all of those associated with the same local facility.

  • msg-format { rfc3164 | rfc5424 } : Configures the message format for each system log server as per RFC3164 or RFC5424. Default: rfc3164.

  • pdu-data { none | hex | hex-ascii } : Specifies output format for packet data units when logged. Format must be one of the following:

    • none : Displays data in raw format.

    • hex : Displays data in hexadecimal format.

    • hex-ascii : Displays data in hexadecimal and ASCII format (similar to a mainframe dump).

  • pdu-verbosity pdu_level : Specifies the level of verboseness to use in logging of packet data units as a value from 1 through 5, where 5 is the most detailed.

  • port number : Specifies an alternate port number for the system log server. Default: 514.

    number must be an integer value from 1 through 65535.

  • rate value : Specifies the rate at which log entries are allowed to be sent to the system log server. No more than the number specified by value is sent to a system log server within any given one-second interval.

    value must be an integer from 0 through 100000. Default: 1000

  • Repeat as necessary to configure extra syslog servers. There is no limit to the number of syslog servers that can be configured.

Configuring Active Logs

Active logs are event logs that are operator configurable on a CLI instance-by-CLI instance basis. Active logs configured by an administrative user in one CLI instance are not displayed to an administrative user in a different CLI instance. Each active log can be configured with filter and display properties that are independent of those configured globally for the system. Active logs are displayed in real time as they are generated.

Active logs are not written to the active memory buffer by default. To write active logs to the active memory buffer execute the following command in the Global Configuration mode: 

logging runtime buffer store all-events

When active logs are written to the active memory buffer, they are available to all users in all CLI instances.

Use the following example to configure active logging in Global Configuration mode: 

logging filter runtime facility facility level report_level

NOTES:

  • Configure the logging filter that determines which system facilities should be logged and at what levels.

  • Repeat for every facility that you want to log.

  • Optional: Configure event ID restrictions by adding the logging disable eventid command. The system provides the ability to restrict the sending of a specific event ID or a range of event IDs to minimize the amount of data logged to that which is most useful. Repeat to disable logging for more event IDs or event ID ranges.

Once all the necessary information has been gathered, the Active log display can be stopped by entering the following command in the EXEC mode: 

no logging active

Configuring Trace Logging

Trace logging is useful for quickly resolving issues for specific sessions that are currently active. They are temporary filters that are generated based on a qualifier that is independent of the global event log filter configured using the logging filter command in the Exec mode. Like event logs, however, the information generated by the logs is stored in the active memory buffer.

All debug level events associated with the selected call are stored.


Important

Trace logs impact session processing. They should be implemented for debug purposes only.

Use the following example to configure trace logs in the Exec mode: 

logging trace { callid call_id | ipaddr ip_address | msid ms_id | username username }

Once all of the necessary information has been gathered, the trace log can be deleted by entering the following command: 

no logging trace { callid call_id | ipaddr ip_address | msid ms_id | username username }

Configuring Monitor Logs

Monitor logging records all activity associated with all of a particular subscriber's sessions. This functionality is available in compliance with law enforcement agency requirements for monitoring capabilities of particular subscribers.

Monitors can be performed based on a subscriber's MSID or username, and are only intended to be used for finite periods of time as dictated by the law enforcement agency. Therefore, they should be terminated immediately after the required monitoring period.

This section provides instructions for enabling and disabling monitor logs.

Enabling Monitor Logs

Use the following example to configure monitor log targets: 

configure 
   logging monitor { ip_addr | ipv6_addr | msid id | username name } 
   end

Repeat to configure additional monitor log targets.

Disabling Monitor Logs

Use the following example to disable monitor logs: 

configure 
   no logging monitor { ip_addr | ipv6_addr | msid id | username name } 
   end

Viewing Logging Configuration and Statistics

Logging configuration and statistics can be verified by entering the following command from the Exec mode: 

show logging [ active | verbose ]

When no keyword is specified, the global filter configuration is displayed as well as information about any other type of logging that is enabled.

The following table provides information and descriptions of the statistics that are displayed when the verbose keyword is used.

Table 3. Logging Configuration and Statistics Commands
Field Description
General Logging Statistics
Total events received Displays the total number of events generated by the system.
Number of applications receiving events Displays the number of applications receiving the events.
Logging Source Statistics
Event sequence ids by process Displays a list of system processes that have generated events and the reference identification number of the event that was generated.
Msg backlog stat with total cnt Displays the number of event messages that have been back logged in comparison to the total number of events generated.
LS L2 filter drop rate Displays the percentage of logging source (LS) layer 2 (L2) event drops.
Abnormal Log Source Statistics Displays abnormal logging source (LS) statistics, if any.
Runtime Logging Buffer Statistics
Active buffer Displays the number of events currently logged in the active memory buffer and a timestamp for the oldest and most recent entries in the buffer.
Inactive buffer Displays the number of events currently logged in the inactive memory buffer.

Viewing Event Logs Using the CLI

Event logs generated by the system can be viewed in one of the following ways:

  • From the syslog server: If the system is configured to send logs to a syslog server, the logs can be viewed directly on the syslog server.

  • From the system CLI: Logs stored in the system memory buffers can be viewed directly from the CLI.

  • From the console port: By default, the system automatically displays events over the console interface to a terminal provided that there is no CLI session active.

This section provides instructions for viewing event logs using the CLI. These instructions assume that you are at the root prompt for the Exec mode.

Procedure

Step 1

Copy the active log memory buffer to the inactive log memory buffer.

When the active log memory buffer is copied to the inactive log memory buffer existing information in the inactive log memory buffer is deleted.

Both active and inactive event log memory buffers can be viewed using the CLI in Exec mode. However, it is preferable to view the inactive log in order to prevent any data from being over-written. The information from the active log buffer can be copied to the inactive log buffer by entering the following command: 

logs checkpoint

Step 2

View the logs by entering the following command: 

show logs

Configuring and Viewing Crash Logs

In the unlikely even of a software crash, the system stores information that could be useful in determining the reason for the crash. This information can be maintained in system memory or it can be transferred and stored on a network server.

The system supports the generation of the following two types of logs:

  • Crash log: Crash logs record all possible information pertaining to a software crash (full core dump). Due to their size, they can not be stored in system memory. Therefore, these logs are only generated if the system is configured with a Universal Resource Locator (URL) pointing to a local device or a network server where the log can be stored.

  • Abridged crash log: Crash event records are automatically generated when a software crash occurs and are stored in flash memory on management cards. The abridged crash log contains a list crash event records along with associated dump files. This log allows you to view event records and dump files via CLI commands.

Crash Logging Architecture

The crash log is a persistent repository of crash event information. Each event is numbered and contains text associated with a CPU (minicore), NPU, or kernel crash. The logged events are recorded into fixed-length records and stored in /flash/crashlog2.

Whenever a crash occurs, the following crash information is stored:

  1. The event record is stored in /flash/crashlog2 file (the crash log).

  2. The associated minicore, NPU, or kernel dump file is stored in the /flash/crsh2 directory.

  3. A full core dump is stored in a user-configured directory.


Important

The crashlog2 file along with associated minicore, NPU, and kernel dumps are automatically synchronized across redundant management cards (SMC, MIO/UMIO). Full core dumps are not synchronized across management cards.

The following behaviors apply to the crash logging process.

  • When a crash event arrives on an active management card, the event record is stored in its crashlog2 file along with the minicore, NPU, or kernel dump file in /flash/crsh2. The crash event and dump file are also automatically stored in the same locations on the standby management card.

  • When a crash log entry is deleted through CLI command, it is deleted on both the active and standby management cards.

  • When a management card is added or replaced, active and standby cards automatically synchronize crash logs and dump files.

  • When a crash event is received and the crash log file is full, the oldest entry in the crash log and its related dump file will be replaced with the latest arrived event and dump file on both management cards. Information for a maximum of 120 crash events can be stored on management cards.

  • Duplicate crash events bump the count of hits in the existing record and update the new record with the old crash record. Additions to the count use the timestamp for the first time the event happened.

Configuring Software Crash Log Destinations

The system can be configured to store software crash log information to any of the following locations:

  • On VPC

    • Flash memory: Accessible by the virtual machine

    • USB memory stick: Installed in the USB slot of the platform (USB slot has been enabled via the hypervisor)

  • Network Server: Any workstation or server on the network that the system can access using the Trivial File Transfer Protocol (TFTP), the File Transfer Protocol (FTP), the Secure File Transfer Protocol (SFTP), or the Hyper-Text Transfer Protocol (HTTP); this is recommended for large network deployments in which multiple systems require the same configuration

Crash log files (full core dumps) are written with unique names as they occur to the specified location. The name format is crash-card-cpu-time-core. Where card is the card slot, cpu is the number of the CPU on the card, and time is the Portable Operating System Interface (POSIX) timestamp in hexadecimal notation.

Use the following example to configure a software crash log destination in the Global Configuration mode: 

configure 
   crash enable [ encrypted ] url crash_url 
   end

NOTES:

  • Repeat to configure additional software crash log destinations. There is no limit to the number of destinations that can be configured.

Viewing Abridged Crash Log Information Using the CLI

You can view abridged crash information that is stored as a set of event records in flash memory on management cards (/flash/crashlog2). Each crash event record has an associated dump file (minicore, NPU or kernel) that can also be displayed (/flash/crsh2)

Follow the instructions in this section to view software crash events that have occurred on the system. These instructions assume that you are at the root prompt for the Exec mode.

Procedure

Step 1

View a list of software crash events by entering the following Exec mode command: 

show crash { all | list | number crash_num }

NOTES:

  • Run show crash list to obtain the number for a specific crash event.

  • Run show crash number crash_num to display the output for the target crash event.

The resulting output may not be the same for all platforms:

Information about similar crash events is suppressed in the output of this command.

Step 2

View the dump file associated with a specific crash event.

The information contained in the dump file helps identify and diagnose any internal or external factors causing the software to crash.

  • Crash # – unique number assigned by StarOS when logging the crash event

  • SW Version – StarOS build release in format: RR.n(bbbbb)

  • Similar Crash Count – number of similar crashes

  • Time of first crash – timestamp when first crash occurred in format: YYYY-MMM-DD+hh:mm:ss

  • Failure message – text of event message

  • Function – code identifier

  • Process – where the crash occurred (Card, CPU, PID, etc.)
  • Crash time – timestamp for when the crash occurred in the format: YYYY-MMM-DD+hh:mm:ss time zone
  • Recent errno – text of most recent error number.
  • Stack – memory stack information
  • Last Bounce – information about the messaging received prior to the crash
  • Registers – memory register contents
  • Current inbound message – hexadecimal information for the current inbound message
  • Address Map
  • Recent heap activity (oldest first)
  • Recent events (oldest first)
  • Profile depth

Reducing Excessive Event Logging

Event logging (evlogd) is a shared medium that captures event messages sent by StarOS facilities. When one or more facilities continuously and overwhelmingly keep sending a high volume of event messages, the remaining non-offender facilities are impacted. This scenario degrades system performance, especially as the number of facilities generating logs increases.

Rate-control of event message logging is handled in the Log Source path. Essentially, every second a counter is set to zero and is incremented for each log event that is sent to evlogd. If the count reaches a threshold before the second is up, the event is sent, queued, or dropped (if the evlogd messenger queue is full).

When any facility exceeds the upper threshold set with this command for the rate of message logging and remains in the same state for prolonged interval, StarOS notifies the user through an SNMP trap or alarm.

A new threshold command allows you to specify the percentage of facility event queue full. When this threshold is exceeded, an SNMP trap and alarm are generated that specifies the offending facility.

The formats for the SNMP traps that are associated with this command are as follows:

  • ThreshLSLogsVolume 
    <timestamp> Internal trap notification <trap_id> (ThreshLSLogsVolume) threshold <upper_percent>%  
measured value <actual_percent>% for facility <facility_name> instance <instance_id>
  • ThreshClearLSLogsVolume 
    <timestamp> Internal trap notification <trap_id> (ThreshClearLSLogsVolume) threshold <upper_percent>%  
measured value <actual_percent>% for facility <facility_name> instance <instance_id>

If a trigger condition occurs within the polling interval, the alert or alarm is not generated until the end of the polling interval.

Both traps can be enabled or suppressed through the Global Configuration mode snmp trap command.

Configuring Log Source Thresholds

There are three Global Configuration mode commands associated with configuring and implementing Log Source thresholds.

  1. threshold ls-logs-volume – sets the parameters for the upper and lower thresholds for generating and clearing traps/alarms respectively.

  2. threshold poll ls-logs-volume interval – establishes the polling interval for this threshold.

  3. threshold monitoring ls-logs-volume – turns monitoring of this threshold on and off.

Use the following example to configure syslog servers: 

configure 
  [ default ] threshold ls-logs-volume upper_percent [ clear lower_percent ] 
  [ default ] threshold poll ls-logs-volume interval duration 
  [ no ] threshold monitoring ls-logs-volume 
  end
Notes:

  • upper_percent and lower_percent are expressed as integers from 0 to 100. Default value for upper_percent is 90%. If lower_percent is not specified, the default clear value is upper_percent.

  • threshold poll ls-logs-volume interval sets the polling interval in seconds. The default interval is 300 seconds (5 minutes).

  • threshold monitoring ls-logs-volume enables or disables this feature.

You can verify the configuration of this threshold by running the Exec mode show threshold command.

Save the configuration as described in the Verifying and Saving Your Configuration chapter.

Checkpointing Logs

Checkpointing identifies logged data as previously viewed or marked. Checkpointing allows you to only display log information since the last checkpoint.

Individual logs may have up to 50,000 events in the active log. Checkpointing the logs results in at most 50,000 events being in the inactive log files. This gives a maximum of 100,000 events in total which are available for each facility logged.

Checkpoint log data through the EXEC mode logs checkpoint command to set the log contents to a well-known point prior to special activities taking place. This command may also be a part of periodic regular maintenance to manage log data.

Checkpointing logs moves the current log data to the inactive logs. Only the most recently check pointed data is retained in the inactive logs. A subsequent check pointing of the logs results in the prior check pointed inactive log data being cleared and replaced with the newly check pointed data. Checkpointed log data is not available for viewing.


Important

Checkpointing logs should be done periodically to prevent the log files becoming full. Logs which have 50,000 events logged discard the oldest events first as new events are logged.


Important

An Inspector-level administrative user cannot execute this command.

Saving Log Files

Log files can be saved to a file in a local or remote location specified by a URL. Use the following EXEC mode command to save log files: 

save logs { url } [ active ] ] [ inactive ] [ callid call_id ] [event-verbosity evt_verboseness ] [ facility facility ] [level severity_level ] [ pdu-data pdu_format ] [ pdu-verbosity pdu_verboseness ] [ since from_date_time [ until to_date_time ] ] [ | { grep grep_options | more } ]

OPTIONS:

  • url: Specifies the location to store the log file(s). url may refer to a local or a remote file and must be entered in the following format.

  • active : Saves data from active logs.

  • inactive : Saves data from inactive logs.

  • callid call_id : Specifies a call ID for which log information is to be saved as a 4-byte hexadecimal number.

  • event-verbosity evt_verboseness : Specifies the level of verboseness to use in the displaying of event data as one of:

    • min : Logs minimal information about the event. Information includes event name, facility, event ID, severity level, date, and time.

    • concise : Logs detailed information about the event, but does not provide the event source within the system.

    • full : Logs detailed information about event, including source information, identifying where within the system the event was generated.

  • facility facility : Specifies the facility to modify the filtering of logged information.

  • level severity_level : Specifies the level of information to be logged in the following list which is ordered from highest to lowest:

    • critical : Logs critical events

    • error : Logs error events and all events with a higher severity level

    • warning : Logs warning events and all events with a higher severity level

    • unusual : Logs unusual events and all events with a higher severity level

    • info : Logs info events and all events with a higher severity level

    • trace : Logs trace events and all events with a higher severity level

    • debug : Logs all events

  • pdu-data pdu_format : Specifies output format for the display of packet data units as one of:

    • none - raw format (unformatted).

    • hex - hexadecimal format.

    • hex-ascii - hexadecimal and ASCII similar to a main-frame dump.

  • pdu-verbosity pdu_verboseness : Specifies the level of verboseness to use in the displaying of packet data units as a value from 1 to 5, where 5 is the most detailed.

  • since from_date_time : Saves only the log information which has been collected more recently than from_date_time

  • until to_date_time : Saves no log information more recent than to_date_time . Defaults to current time when omitted.

  • from_date_time and to_date_time must be formatted as YYYY:MM:DD:HH:mm or YYYY:MM:DD:HH:mm:ss. Where:

    • YYYY = 4-digit year

    • MM = 2-digit month in the range 01 through 12

    • DD = 2-digit day in the range 01 through 31

    • HH = 2-digit hour in the range 00 through 23

    • mm = 2-digit minute in the range 00 through 59

    • ss = 2 digit second in the range 00 through 59

    to_date_time must be a time which is more recent than from_date_time .

    Using the until keyword allows for a time range of log information; using only the since keyword will display all information up to the current time.

  • grep grep_options | more : Pipes (sends) the output of this command to the specified command. You must specify a command to which the output of this command is sent.

Event ID Overview


Important

The use of event IDs depends on the platform type and the licenses running on the platform.

Identification numbers (IDs) are used to reference events as they occur when logging is enabled on the system. As described previously, logs are collected on a per facility basis. Each facility possesses its own range of event IDs as indicated in the following table.

Event Severities

The system provides the flexibility to configure the level of information that is displayed when logging is enabled. The following levels are supported:

  • critical: Logs only those events indicating a serious error has occurred that is causing the system tor a system component to cease functioning. This is the highest severity level.

  • error: Logs events that indicate an error has occurred that is causing the system or a system component to operate in a degraded state. This level also logs events with a higher severity level.

  • warning: Logs events that may indicate a potential problem. This level also logs events with a higher severity level.

  • unusual: Logs events that are very unusual and may need to be investigated. This level also logs events with a higher severity level.

  • info: Logs informational events and events with a higher severity level.

  • trace: Logs events useful for tracing and events with a higher severity level.

  • debug: Logs all events regardless of the severity.

Each of the above levels correspond to the "severity" level of the event ID. Therefore, only those event IDs with a "severity" level equal to the logging level are displayed.

Understanding Event ID Information in Logged Output

This section explains the event information that is displayed when logging is enabled.

The following displays a sample output for an event that was logged. 

2011-Dec-11+5:18:41.993 [cli 30005 info] [8/0/609 cli:8000609 _commands_cli.c:1290] [software internal system] CLI session ended for Security Administrator admin on device /dev/pts/2
The following table describes the elements of contained in the sample output.
