CPU spiking

Post by nagiostra »

On my linux servers, the CPU seems to bounce all over. It will be close to 100% then it will be 2%. I run the check every 5 minutes. Is there a way to measure the average over the 5 minutes? Should I be concerned if it's close to 100% if it's only that high for a little while?

You might want to watch top/htop on a few of the servers while watching nagios for the same servers. Then decide if it matters to you.
There are may cpu plugins and agents probably have internal cpu checks as well. You may want to check how you're doing it now and experiment with arguments available and different plugins.
