You can run: $ sudo munin-run --servicedir=/usr/share/munin/plugins ip_ suggest to see what IPs it's suggesting. If they look odd, perhaps check your firewall. > And why am I seeing only stats for eth1 and eth3? What happened to eth0, eth2 and eth5? The if_ and if_err_ plugins look in /proc/net/dev for interfaces to monitor. Perhaps those devices weren't there when you ran suggest? > > It looks like I have anly some things that were there when I was > building the server. Is there a way to sort of reset the plugins dir > and have it regenerated? When munin is installed, it installs what seem like suitable plugins. You are free, though to add or remove symlinks to /etc/munin/plugins as you see fit. To see what plugins may be suitable for your system, run: $ sudo munin-node-configure --suggest For more details, you might want to start reading here: http://munin-monitoring.org/wiki/munin-node-configure -- Darac Marjal
