Hardware Device Health

The Hardware Device Health script monitors overall hardware device health using the Temperature Sensor, Fan Sensor, and Fault Finder scripts. When any of the monitors trigger an alert because of temperature, fan status, or ethernet status anomalies, the agent will collect relevant diagnostic information.


This script requires AOS-CX firmware version 10.04.000X or later.

  • Rate of Rx CRC Error Packets (measured in packets per second)

Both of these monitors have default values set as their thresholds. The network administrator can elect to modify these parameters to adapt them for a specific network environment.
