I use Icinga 2 with the Graphite module for graphics. Some of my checks are showing graphs (basically the standard checks), others don’t.
Now I did an icinga plugin myself. In the output i define the performance data. So at the check-page there is shown “Label Value Warning Critical”
The value.wsp file for the check has also the monitored values in it, one for every minute how it should be.
The Problem is: the is no graph, it says “no data”
Has anyone an idea what the problem could be?
