Notification and Alert

Architectural Overview

A Cisco Policy Suite (CPS) vDRA deployment comprises multiple virtual machines (VMs) with multiple running containers deployed for scaling and high availability (HA) purposes. The monitoring and alerting system of the CPS vDRA deployment is centered around alert definition, metric gathering, and SNMP trap forwarding. The high-level architecture is shown below:

Major Components

Alert Definition

Alert definition occurs when an end user (or external system) configures the system via CLI, NETCONF, or RESTCONF interfaces with Alert rules. The system takes these alert rules and pushes the definitions into the Prometheus processes running within the cluster. The system does not provide a fixed set of alerts but provides a sample list of common alerts an operator may want to configure.

Metric Gathering

At the core of the alerting framework, the system runs multiple Prometheus processes (http://prometheus.io) which monitors the system and track metrics which can be used for triggering alerts. The default Prometheus instance that monitors the system tracks metrics at a 5 second interval for 24 hours.

SNMP Trap Forwarding

Once an alert is triggered the Prometheus server forwards that alert to the active control/Cluster Manager node. These alerts are forwarded based on configuration to external NMS systems using either SNMPv2 or SNMPv3.

Technical Architecture

Cisco Policy Suite is deployed as a distributed virtual appliance. The standard architecture uses Hypervisor virtualization. Multiple hardware host components run Hypervisors and each host runs several virtual machines. Within each virtual machine, one-to-many internal CPS components can run. CPS monitoring and alert notification infrastructure simplifies the virtual physical and redundant aspects of the architecture.

Protocols

The CPS monitoring and alert notification infrastructure provides a simple standards-based interface for network administrators and NMS (Network Management System). SNMP is the underlying protocol for all alert notifications. Standard SNMP notifications (traps) are used throughout the infrastructure.

Alerts are triggered from either the Cluster Manager or Control virtual machines if the Cluster Manager is not active.

SNMP Object Identifier and Management Information Base

Cisco has a registered private enterprise Object Identifier (OID) of 26878. This OID is the base from which all the aggregated CPS metrics are exposed at the SNMP endpoint. The Cisco OID is fully specified and made human-readable through a set of Cisco Management Information Base (MIB-II) files.

The current MIBs are defined as follows:

Table 1. MIBs
MIB Filename	Purpose
BROADHOP-MIB.mib	Defines the main structure include structures and codes.
BORADHOP-NOTIFICATION-MIB.mib	Defines Notifications/Traps available.

SNMP Notifications

SNMP Notifications in the form of traps (one-way) are provided by the infrastructure. CPS notifications do not require acknowledgments. The traps provide both:

Proactive alerts that the predetermined thresholds have been passed. For example, a disk is nearing capacity or CPU load is too high.
Reactive alerting when system components fail or are in a degraded state. For example, a process died or network connectivity outage has occurred.

Notifications and traps are categorized by a methodology similar to UNIX System Logging (syslog) with both Severity and Facility markers. All event notifications (traps) contain these markers.

Facility
Severity
Source (device name)
Device time

These objects can be used to identify where the issue lies and the Facility (system layer) and the Severity (importance) of the reported issue.

Facility

The generic syslog facility has the following definitions:

Note

Facility defines a system layer starting with physical hardware and progressing to a process running in a particular application.

Table 2. Syslog Facility
Number	Facility	Description
0	Hardware	Physical Hardware - Servers SAN NIC Switch and so on
1	Networking	Connectivity in the OSI (TCP/IP) model
2	Virtualization	VMware ESXi (or other) virtualization
3	Operating System	Linux OS
4	Application	Application (CPS Session Manager, CPS Binding Database, and so on)
5	Process	Specific process

There may be overlaps in the Facility value as well as gaps if a particular SNMP agent does not have full view into an issue. The Facility reported is always shown as viewed from the reporting SNMP agent.

Severity

In addition to Facility each notification has a Severity measure. The defined severities are directly from UNIX syslog and defined as follows:

Table 3. Severity Levels
Number	Severity	Description
0	Emergency	System is unusable.
1	Alert	Action must be taken immediately.
2	Critical	Critical conditions.
3	Error	Error conditions.
4	Warning	Warning conditions.
5	Notice	Normal but significant condition.
6	Info	Informational message.
7	Debug	Lower level debug message.
8	None	Indicates no severity.
9	Clear	The occurred condition has been cleared.

For the purposes of the CPS Monitoring and Alert Notifications system, Severity levels of Notice Info and Debug are usually not used.

Warning conditions are often used for proactive threshold monitoring (for example, Disk usage or CPU Load) which requires some action on the part of administrators but not immediately.

Conversely, Emergency severity indicates that some major component of the system has failed and that either core policy processing session management or major system functionality is impacted.

Categorization

Combinations of Facility and Severity create many possibilities of notifications (traps) that might be sent. However, some combinations are more likely than others. The following table lists some Facility and Severity categorizations:

Table 4. Severity Categorization
Facility.Severity	Categorization	Possibility
Process.Emergency	A single part of an application has failed.	Possible but in an HA configuration very unlikely.
Hardware.Debug	A hardware component has sent a NA debug message.	NA
Operating System.Alert	An Operating System (kernel or resource level) fault has occurred.	Possible as a recoverable kernel fault (on a vNIC for instance).
Application.Emergency	An entire application component has failed.	Unlikely but possible (load balancers failing for instance).

It is not possible to quantify every Facility and Severity combination. This is primarily driven by the fact that the alert rules can be configured to meet each operator's environment. However, greater experience with CPS leads to better diagnostics. The CPS Monitoring and Alert Notification infrastructure provides a baseline for event definition and notification by an experienced engineer.

Emergency Severity Note

Caution Emergency severities are very important! As a general principle, alerts should only be defined with an Emergency-severity trap if the system becomes inaccessible or unusable in some way. An unusable system is rare but might occur if multiple failures occur in the operating system virtualization networking or hardware facilities.

Notifications and Alerting

The CPS Monitoring and Alert Notification framework provides the following SNMP notification traps (one-way). Traps are either proactive or reactive. Proactive traps are alerts based on system events or changes that require attention (for example, Disk is filling up). Reactive traps are alerts that an event has already occurred (for example, an application process failed).

Component Notifications

Components are devices that make up the CPS system. These are systems level traps. They are generated when some predefined thresholds is crossed and are defined in the alerting configuration of the system. User can modify and change these using the alert definition commands.

Component notifications are defined in the BROADHOP-NOTIFICATION-MIB as follows:

 broadhopQNSComponentNotification NOTIFICATION-TYPE OBJECTS {
   broadhopComponentName, 
   broadhopComponentTime, 
   broadhopComponentNotificationName,
   broadhopNotificationFacility,
   broadhopNotificationSeverity,
   broadhopComponentAdditionalInfo }	 
STATUS current	 
DESCRIPTION "
Trap from any QNS component - i.e. device.
	 
"
::= { broadhopProductsQNSNotifications 1 }

Each Component Notification contains:

Name of the Notification being thrown (broadhopComponentNotificationName)
Name of the device throwing the notification (broadhopComponentName)
Time the notification was generated (broadhopComponentTime)
Facility or which layer the notification came from (broadhopNotificationFacility)
Severity of the notification (broadhopNotificationSeverity)
Additional information about the notification, which might be a bit of log or other information.

The following table provides the list of supported alarms:

Alert Rules

Alert Rules Configuration

The following commands are used to configure alert rules:

scheduler#config

scheduler(config)# alert rule <rule_name>

where, <rule_name> is the name of the alert rule. For example, test

Value for 'expression' (<string>): <expression based on the stats>

where, <expression based on the stats> is the expression. For example, test>1

Value for 'message' (<string>): <message string to be sent in the alarm message>

where, <message string to be sent in the alarm message> is the message to be sent in the alarm. For example, testing

Value for 'snmp-clear-message' (<string>): <message string for clear alarm>

where, <message string for clear alarm> is the string for the clear message. For example. test clear

scheduler(config-rule-test)#
scheduler(config-rule-test)# snmp-facility
Possible completions:
  application  hardware  networking  os  proc  virtualization

scheduler(config-rule-test)# snmp-facility <SNMP facility to be provided for this alert>

where, <SNMP facility to be provided for this alert> is the facility to be provided for this alert. For example, application

scheduler(config-rule-test)# event-host-label <provide the node details>

where, <provide the node details> is used to provide node details. For example, instance

scheduler(config-rule-test)# snmp-severity
Possible completions:
  alert  critical  debug  emergency  error  info  none  notice  warning

scheduler(config-rule-test)# snmp-severity <SNMP severity to be send for this alert>

where, <SNMP severity to be send for this alert> is the severity level to be used for alert rule. For example, critical

scheduler(config-rule-test)# duration <time>

where, <time> causes Prometheus to wait for a certain duration between first encountering a new expression output vector element (like, an instance with a high HTTP error rate) and counting an alert as firing for this element. Elements that are active, but not firing yet, are in pending state.

scheduler(config-rule-test)# commit
Commit complete.
scheduler(config-rule-test)# end

Sample Configuration

The alert rules configuration are for reference only. Here is the configuration with sample values:

You can configure your alert rules based on your requirements.

scheduler#config
scheduler(config)# alert rule test
Value for 'expression' (<string>): test>1
Value for 'message' (<string>): testing
Value for 'snmp-clear-message' (<string>): test clear
scheduler(config-rule-test)#
scheduler(config-rule-test)# snmp-facility
Possible completions:
  application  hardware  networking  os  proc  virtualization
scheduler(config-rule-test)# snmp-facility application 
scheduler(config-rule-test)# event-host-label instance 
scheduler(config-rule-test)# snmp-severity
Possible completions:
  alert  critical  debug  emergency  error  info  none  notice  warning 
scheduler(config-rule-test)# snmp-severity critical
scheduler(config-rule-test)# duration 30s 
scheduler(config-rule-test)# commit
Commit complete.
scheduler(config-rule-test)# end

To display all the configured alert rules use the following command:

scheduler# show running-config alert | tab

                            EVENT

Sample Alert Rules

You can configure alert rules based on your requirements. For sample configuration, refer to Sample Alert Rule Configuration.

Note

event-host-label value is used as a key in the alarm map. So, configure the correct value based on your requirements while configuring alert rules.

Note

Grafana can be used to see all the statistics generated by the system and based on these statistics alerting rules can be configured.

Note

Alert SNMP command includes an optional parameter named add-vm-info that you can use to specify whether or not the VM name is prepended in the SNMP alarm in broadhopComponentName. For example, broadhopComponentName: VMName/containerName. By default, the parameter is set to true. If set to false, broadhopComponentName does not prepend VM name. For example, broadhopComponentName: containerName. The following table includes sample alert rules when add-vm-info is set to false. For more information about this parameter and the command, see the vDRA Operations Guide.

Health Status of Service

On getting the Qns Java Process State alert, the user has to access the system and check the diagnostics logs of the service to get the exact issue with the service. To access the system and check the diagnostics log, run the following command:

show system diagnostics | include <service_name>

For example:

scheduler# show system diagnostics | include diameter-endpoint-s1
system diagnostics diameter-endpoint-s1 serfHealth 1
system diagnostics diameter-endpoint-s1 service:cisco-policy-app 1
system diagnostics diameter-endpoint-s1 service:cisco-policy-app 2

NMS Destination Configuration

The following configuration is for reference only:

You can configure the NMS destination based on your requirements.

Example: SNMPv2

scheduler#config
scheduler(config)# alert snmp-v2-destination "10.1.1.1"
Value for 'community' (<string>): "cisco"   
scheduler(config-snmp-v2-destination-10.1.1.1)# commit
Commit complete.
scheduler(config-snmp-v2-destination-10.1.1.1)# end

where, "10.1.1.1" is the SNMPv2 NMS destination address.

Example: SNMPv3

scheduler# config
scheduler(config)# alert snmp-v3-destination <nms_ip> e.g. 10.1.1.2
Value for 'user' (<string>): <username> e.g. cis_user
Value for 'auth-password' (<string>): <password string > e.g. cisco-123
Value for 'privacy-password' (<string>): <password string> e.g. cisco-123
scheduler(config-snmp-v3-destination-10.1.1.2)# auth-proto 
[MD5,SHA] (SHA): SHA
scheduler(config-snmp-v3-destination-10.1.1.2)# privacy-p   
Possible completions:
  privacy-password  privacy-protocol
scheduler(config-snmp-v3-destination-10.1.1.2)# privacy-protocol 
[AES,DES] (AES): AES
scheduler(config-snmp-v3-destination-10.1.1.2)# engine-id 
(<string>) (0x0102030405060708): 0x0102030405060708
scheduler(config-snmp-v3-destination-10.1.1.2)# commit
Commit complete.
scheduler(config-snmp-v3-destination-10.1.1.2)# end
scheduler#

where, "10.1.1.2" is the SNMPv3 NMS destination address.

All the configured NMS destinations in the system can be displayed using the following command:

scheduler# show running-config alert | tab
NMS                  
ADDRESS   COMMUNITY
