Description: Show device CPU load in %, it's the snapshot of CPU load when getting the values.
What is zySysMgmtCPUUsage?
This read-only integer reports the device's CPU load as a percentage, captured as a snapshot at the moment of the SNMP query. An admin polls this periodically to watch for sustained high CPU utilization that could indicate a control-plane overload, such as excessive broadcast traffic or a runaway management process. A reading of 95 sampled repeatedly would prompt the admin to investigate what's driving CPU load on the switch.
