When you use the 'top' command on a stack, which CPU is it showing you?

[Stanley_Riley_J]

We have a 5 switch stack of x460-48p. Our monitoring software, Solarwinds, is alerting us to high CPU usage very frequently and intermittently on this switch stack. However, when I use the 'top' command, I don't see CPU usage as high as what is being reported.

What CPU information is being shown when I run the 'top' command on the master of the stack?

What are some possibilities for the high CPU being reported?

Thanks,
Stan

I also made sure that all edge ports were running edge-safeguard, which they are. So I can check that off of my list.

I'm running out of ideas as to why high CPU utilization is being reported.

/sigh

It is possible that SolarWinds is giving you a false positive as you suspected. Since you say that you do not see any high utilization when you use top.

No loops were detected using ELRP for any of our VLANs.

Any other suggestions?

You could have a loop. You could run elrp-client oneshot to find one. Excessive traffic hitting the slow-lane (cpu) of switch, instead of being moved to ASIC....

What process is high in top?
