Measures reported by CisNexusTempSenTest

The Cisco Nexus Switch is by default, provided with built-in automatic temperature sensors for each of the modules (Supervisor, I/O and Fabric). Whenever a temperature sensor detects an abnormal temperature, then the module corresponding to that temperature sensor is shutdown. If an abnormal temperature is detected by the temperature sensor corresponding to the Supervisor module and high-availability is not available, then you have two minutes of time to decrease the temperature beyond which the module will be shutdown. If the modules are shutdown frequently, then the performance of the Cisco Nexus Switch may degrade gradually. To avoid this, it is essential to monitor the operational state and the temperature of each module at regular intervals. The CisNexusTempSenTest test helps administrators in this regard.

This test auto-discovers the temperature sensors of the Cisco Nexus Switch and reports the current status of each temperature sensor and the current temperature of each module detected by its corresponding temperature sensors.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Sensor_status Indicates the current state of this temperature sensor.   The values reported by this measure and its numeric equivalents 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 state of the sensor of this temperature unit. The graph of this measure however, represents the status of a server using the numeric equivalents only - 1 to 3.
Power Indicates the current temperature detected by this temperature sensor. Celsius Ideally, the value of this measure should be within the admissible temperature range.
