Monitoring the System

This chapter provides information for monitoring system 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 provide the most useful and in-depth information for monitoring the system. For additional information on these and other show command keywords, refer to the Exec Mode show Commands chapter of the Command Line Interface Reference.


Note

A VPC-DI or VPC-SI virtual machine (VM) has no knowledge of the hypervisor under which it is running or the commercial off-the-shelf (COTS) server. To monitor the status of the hypervisor and COTS server, refer to the user documentation supplied with these components of this system.


Important

In Release 21.1 and forward, use the do show command to run all Exec Mode show commands while in Global Configuration Mode. It is not necessary to exit the Config mode to run a show command. The pipe character | is only available if the command is valid in the Exec mode.

SNMP Notifications

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

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.

Important
The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).

Important
Some commands have different outputs depending on the platform type.

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 Exec Mode Commands chapter of the Command Line Interface Reference for detailed information on using this command.
