Dell PowerConnect Switches: CPU load

Distribution: official part of Check_MK
License: GPL
Supported Agents: SNMP

This check monitors the CPU load on Dell PowerConnect Switches which support the RADWARE-MIB. It will check the percentage of the CPU load for the following states:

- 1 second (the load average of when the check ran). - 60 seconds (the "average" over the last 60 seconds at the time the check occurred). - 5 minutes (the "average" over the last 5 minutes, at the time the check occurred).

A single service will be created showing the percentage of CPU use at the time the check occurred (using the 1 second load average). However, charts are created for each of the load averages, using values obtained during each execution of the service check.

The state of the check will return a WARNING value when the percentage of the 1 second load value exceeds the warning threshold, and is less then the critical threshold. If the load values exceeds the critical threshold, then it will return a CRITICAL state.

Currently, testing has been completed with the Dell PowerConnect 5448 and 5424 models, however the service check may work with other models.

Discovery

During the inventory phase of check_mk, it will identify one service CPU, as long as the MIB defined above is supported on the switch.
