Dell PowerConnect Switches: Power Supply Sensors
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:
- 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.
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.
