Measures reported by MLXFanSensorTest

Fan provides cooling airflow to various components of switch, specially the CPU which produces a large quantities of heat. Optimal operation of fan is key to channelling the heat out of the system and keeping the switch temperature with operable range. That's the reason it is very important to monitor the fan to ensue that it is workign fine and catch if there is any problem before the switch circuit is damaged due to heat.

This test monitors the fan by reading the fan rpm sensor value and operational status, keeping an eye on this, administrators will have enough time to act if fan is malfunctioning.

Outputs of the test: One set of result for each fan sensor in the switch

Descriptor: Fan sensor

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
SensorValue Indicates the rotations per min sensor value to denote the fan speed. RPM

If the speed of fan is not within operating range, there amy be some issue with fan.
OperationalStatus Indicates the operational status of fan RPM sensor to denote if the sensor is working or not.  

The values reported by this measure and its numeric equivalent are mentioned in the table below:

Measure Value Numeric Value
Ok 1
Unavailable 2
Non operational 3

Note:

By default, this measure reports the Measure Values listed in the table above to indicate the current status of this fan. The graph of this measure, however, represents the status of the fan using the numeric equivalents only.
