Monitoring the Service

This chapter provides information for monitoring service status and performance using the show commands found in the Command Line Interface (CLI). These command have many related keywords that allow them to provide useful information on all aspects of the system ranging from current software configuration through call activity and status.

The selection of keywords described in this chapter is intended to provided the most useful and in-depth information for monitoring the system. For additional information on these and other show command keywords, refer to the Command Line Interface Reference.

In addition to the CLI, the system supports the sending of Simple Network Management Protocol (SNMP) traps that indicate status and alarm conditions. Refer to the SNMP MIB Reference for a detailed listing of these traps.

Monitoring System Status and Performance

This section contains commands used to monitor the status of tasks, managers, applications and other software components in the system. Output descriptions for most of the commands are located in the Statistics and Counters Reference.

Configuring the S-GW to Include IMSI/IMEI in Logging Events

The S-GW can be configured to provide the IMSI/IMEI in the event log details for the following system event logs of type error and critical, if available. If the IMSI is not available, the S-GW will make a best effort to obtain the IMEI.

Configuring S-GW to Include IMSI/IMEI in Event Logs

The include-ueid keyword has been added to the logging command in Global Configuration Mode. When enabled, the previously mentioned system events of type error and critical will provide the IMSI/IMEI in the logging details, if available.

Use the following example to enable/disable the logging include-ueid functionality. 

configure 
   logging include-ueid   
   no logging include-ueid   
   end

Notes:

  • no disables the inclusion of the IMSI/IMEI in system event logs of type error and critical
  • To determine if logging include-ueid is enabled on the S-GW, use the show configuration command in Exec Mode. This command will indicate one of the following:
    • logging include-ueid (when enabled)
    • no logging include-ueid (when disabled)

Clearing Statistics and Counters

It may be necessary to periodically clear statistics and counters in order to gather new information. The system provides the ability to clear statistics and counters based on their grouping (PPP, MIPHA, MIPFA, etc.).

Statistics and counters can be cleared using the CLI clear command. Refer to the Command Line Reference for detailed information on using this command.
