Howto capture if CPU spikes to 100%?

[paul_a2]

Running zenarmor etc, and in previous UI I could see CPU spiking quite high (100%) in UI but that might have been due to loading UI of Opnsense.

Any tips on howto capture if CPU spikes at 100%/any of cores spikes at 100%? Do I need to build some script and capture averages, or could I install the Telegraf-plugin and export CPU data that way?

Dunno, but monit does it by default when CPU usage is >75%. Perhaps adjust that.

Thx - like you said not exactly but could from UI see load averages again (monit->status) when enabled cpu monitoring. Guessing my cpu run out of power time to time, zenarmor :/
