> Monitoring Hardware Status
> This chapter describes how to use the command line interface (CLI) show commands to monitor system status and performance. These command have related keywords that you can use to get 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 provides useful and in-depth information for monitoring the hardware. For additional information on these and other show command keywords, refer to the Command Line Interface Reference.
> 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 Guide for a detailed list.
> Monitoring Hardware Status
> Use the commands contained in this section to monitor the status of the hardware components in the chassis. For output descriptions for most of the commands, refer to the Counters and Statistics Reference.
> Important: The commands or keywords and variables are dependent on platform type, product version, and installed license(s). Some commands produce different outputs, depending on the platform type.
> Hardware Monitoring Commands

> To do this: | Enter this command:
> View the Status of the Power System
> View the status of the PFUs | show power chassis
