> Monitoring the Service
> This chapter provides information for monitoring service status and performance using the show commands through 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 Guide 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.

> 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 Command Line Interface Reference for detailed information on using this command.
