eG Monitoring  

Measures reported by ARSWCpuUsageTest

One of the probable reasons for the poor performance of the target Arista switch is excessive CPU utilization. Administrators should hence continuously track how well the switch utilizes CPU resources, so that abnormal usage patterns can be proactively detected and corrected to ensure peak performance of the switch.

This test helps the administrators to monitor the CPU resource contention in the Arista switch and also helps to sort out the solutions for what caused this contention - resource-hungry user processes, CPU-intensive system processes or low-priority (Nice) jobs?

Outputs of the test : One set of results for the target Arista Switch that is to be monitored.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
User_cpu Indicates the percentage of CPU time spent on user processes. Percent Compare the values of these metrics to know which processes are hogging CPU resources.
System_cpu Indicates the percentage of CPU time spent on system processes. Percent
Nice_cpu Indicates the percentage of CPU time spent on low priority processes. Percent
Idle_cpu Indicates the percentage of time the CPU was idle. Percent An idle time of less than 20% is indicative of excessive CPU usage.
