Server monitoring software that will show each cpu seperatley

Question

We have been using New Relic to monitor our server load but it aggregates all of the CPUs into one measure. Is there a good tool that is similar but will show individual CPU load?

Answer 1

There is munin. I found this page http://www.matija.si/system-administration/2014/04/01/a-munin-plugin-to-monitor-each-cpu-core-separately/ talking about a plugin that does just what you want.

Also, I know this isn't like new relic, but I'm wondering if atop will help you.

It shows individual cores/cpus. It also shows when things are maxed out and turns the line red to catch your attention. It shows all sorts of useful information about cpu, memory, swap, disk io, network io, etc...

The only drawback is that it's not a web based, metric gathering daemon.
