Dell PowerConnect Switches: Temperature Sensors
|Distribution:||official part of Check_MK|
This check monitors the temperature inside Dell PowerConnect Switches which support the
RADLAN-MIB/NetDiscover MIB. It will retreive the temperature (Celcius), and the state
of the temperature sensor.
A single service will be created showing the internal temperature at the time the check
occurred However, two charts are created that plot the state of the sensor, and the
value returned for the temperature.
The state of the check will return an OK value if the sensor is working properly, otherwise
it will return a WARNING state if the sensor is no longer available, or a CRITICAL state
if the sensor becomes non-functional.
The temperature can also trigger a WARNING or CRITICAL nagios state if the temperature
exceeds the defined threshold values for each state.
By default, the temperature returned by the SNMP check is returned in Degrees Celcius.
The Dell PowerConnect manuals indicate the hardware can fail at any temperature over
41 or 42 degrees Celcius, depending on the model.
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 identify one service Temperature,
as long as the MIB defined above is supported on the switch.
