I had a munin plugin that suddenly stopped reporting, and in the munin-node log there were lots of errors like this:
2007/06/27-06:50:26 Plugin timeout: myplugin : Interrupted system call
So it looks like the plugin is taking too long, but how to extend the timeout? Seems I’m not alone in wondering this. So I had a rummage in the source of munin-node, and it seems to want a ‘timeout’ parameter in its config. So I added a simple
timeout 60 to munin-node.conf and it worked! However, that’s a global setting rather than a per-plugin timeout, so I took a flying guess at putting the same directive in my plugin spec in /etc/munin/plugin-conf.d/munin-node like this:
And that worked too!
