Munin memory graph missing

Question

I just installed Munin on Ubuntu 12.04. I had used it previously on a different machine running 10.04 and it has a beautiful memory graph. For some reason it is not showing up on my new install. Any ideas where to look?

Answer 1

Ok, figured it out. There's a huge list of plugins in /usr/share/munin/plugins. I just ran:

ln -s /usr/share/munin/plugins/memory memory
sudo restart munin-node

Showed up right away.

Answer 2

I'm not sure I've understand you, but are you talking about free memory or total memory?

free memory: free -m - shows the statistics in megabytes. -g for gigabytes, -k for kilobytes, nothing or -b for bytes.

Total memory: just look for Details on the dash.

Please explain again if I'm not reply as you want. :)
