Distribution: official part of Check_MK

Supported Agents: SNMP

This check monitors the various PSU sensors on a Dell PowerConnect switch that supports the DELL-VENDOR-MIB. It will monitor the state of the PSU itself, depending on the state returned by the PSU.

If a switch has more then one PSU sensor, it will create a service for EACH sensor. However, if a switch has any PSU units that are not connected up to the sensor suite, or there is an empty PSU bay, they will not be ignored by this check.

A PSU that is running normally will return an OK nagios state. Any PSU that are in a warning or is not present (if it was previously present) will return a WARNING nagios state. If a PSU is in a critical or is non-functional according to the sensor will return a CRITICAL nagios state. Lastly, if a PSU is in a "shutdown" state, it will return an UNKNOWN nagios state.

The service will show the state of the PSU, as well as the power source state. The source of the power can be one of the following:

- Unknown - Alternating Current - Direct Current - External Power Supply - Internal Redundant

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

Check parameters

None.

Performance data

Each PSU sensor uses a single variable value (0..1) representing the state of the PSU itself. A 1 represents a normal "ON" state, where as a 0 represents any "OFF", which can mean warning, critical, shutdown, not present (only if previously present), or not functioning. This is simply to chart the state of the PSU itself.

Inventory

During the inventory phase of check_mk, it will create one or more service Sensor psX_unitX entries, as long as the MIB defined above is supported on the switch.

Configuration variables

None.
