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.

This chapter includes the following topics:

Monitoring System Status and Performance

Including the IMSI/IMEI in System Event Logs of Type Error and Critical

The P-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 P-GW will make a best effort to obtain the IMEI.

Configuring the P-GW to Include the IMSI/IMEI in System Event Logs of Type Error and Critical

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. 

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.
  • Use the show configuration command to view the current configuration status of the logging include-ueid command.
    • 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.
