Munin - multimemory errors on Ubuntu 11.10


#1

Hi,

I couldnt find any record of these errors im getting, maybe someone can point me in the right direction?

On Ubuntu 11.10, installed and configured munin and can visit the munin page.

Then tried to install the multimemory plugin with following commands…

cd /usr/share/munin/plugins
sudo wget http://wiki.kartbuilding.net/multimemory
sudo chmod 755 multimemory
sudo ln -s /usr/share/munin/plugins/multimemory /etc/munin/plugins/

sudo nano /etc/munin/plugin-conf.d/munin-node
#add the following:
[multimemory]
env.names apache2 named mysqld

sudo /etc/init.d/munin-node restart
#That should do it. Wait and watch for the graphs.

munin-node-configure shows ‘yes’ next to multimemory.
No multimemory graph shows so I get this in munin-node.log,
