Package: munin-node Version: 1.2.5-1 Severity: normal
Hi, It seems that by default the munin-node program waits for 10 seconds for a plugin to respond. This value is present in the source of munin-node and can be over-ridden by a setting in munin-node.conf. I suggest that the default munin-node.conf should set a higher value. This is based on an experience yesterday. Someone decided to use wget to recursively download a website from my server that included lots of dynamic content (a PHP forum). This caused the server load to be very high for about an hour. Apache spawns many threads/processes (about 100 I think) to deal with requests, and if they are all busy then another process, e.g. a munin plugin, will get only about 1% of the CPU. So a few of the plugins took more than 10 seconds to respond. This is important because it's exactly in situations like this (i.e. a very high load on the server) when you want to be able to see what is going on. Instead, when I look at this period, I see gaps in the graphs.
