We are running EOS 4.22.3 M, SplunkUniversalForwarder 6.6.2 and AristaApp 1.6.0, one thing we noticed with all these latest extensions is the high CPU load averages when running splunk-forwarder. If we shutdown the splunk load averages goes down to an average of 0.40 per minute, with splunk running it is always more than 1.00.

Below are the details.

Is there any Arista recommended Index intervals, we are trying to understand why the high CPU usage with current splunk. Previously we were running EOS 4.20.10M, SUF 7.1.2, AristaApp 1.5.0 and CPU load averages were pretty normal.

Please suggest what are the recommended versions of extensions for EOS 4.22.3M and index intervals.

Hello Ravi,

The high CPU load could be observed because of the short interval time between the indexes in the said EOS version. Based on our testing and understanding, the following steps have brought the CPU load down:

  1. Increase inventory interval to 3600s (index inventory interval 3600)
  2. Increase interface-counter to a higher value 1800s (index interface-counters interval 1800) or set it to a default value 60s (index interface-counters interval 60)
