Munin - Netstat Graph

Question

I've installed Munin on a couple of our servers (CentOS) so I'll have some way to monitor what is going on.

In one server it looks good with proper value-ranges:

In others it looks like this:

Has anyone run into this ? I can't find any info on such an issue?

Thanks, Alon

Could you telnet to one bad server and one good server on port 4949 (from the central munin server), do a `config NAME-OF-PLUGIN`, and edit the results in each case into your question above? — MadHatter, Mar 28 '12 at 08:04
Cool I see that the one working well has this: graph_args -l 0 --base 1000 while the one that isn't working has this: graph_args --base 1000 --logarithmic — Alon, Mar 28 '12 at 08:31
Maybe a bit of an awkward place to change this, either way I updated it directly in the plugin code in /etc/munin/plugins/netstat and it fixed it. Thanks for the help :) — Alon, Mar 28 '12 at 08:36
Glad we fixed it. I've written my comment up as an answer, in the hope that you will see fit to accept it. — MadHatter, Mar 28 '12 at 08:39

If you telnet to a bad server and a good server on port 4949, from the central munin server, and do a config NAME-OF-PLUGIN, I expect that you'll see that the bad plugin passes graph_args --logarithmic and the good one doesn't. Fix the one that does, and you should stop getting log-lin graphs.
