I've installed Munin on a couple of our servers (CentOS) so I'll have some way to monitor what is going on.
[Sorry the images arn't embedded in, as it turns out new user's can't post images directly]
In one server it looks good with proper value-ranges: Good Graph Link
In others it looks like this: Bad Value Range Graph
Has anyone run into this ? I can't find any info on such an issue?
