munin

I have a web server: ubuntu apache+php app+postgresql and a stats server: ubuntu apache+php - piwik and munin2 installed.

The communication for munin2 is made through ssh.

In munin i see a lot of system cpu activity, that I assume it it because of apache (i see 5 or 6 apache instances using ~5% CPU on top)

I was not having this system CPU activity before.

Does anyone knows how can I see where that comes from?
