95th Percentile Datasource
I've been asked to re-implement some monitoring that we used to aggregate from MRTG data, and I'm immediately baffled because it looks like there's a built-in datasource to do what we need (at leas...

Hm, i'll check to see if anything is going on with support that's affecting more than you.
It's very possible to graph a datapoint that isn't defined in the DataSource. This is exactly what I was referring to when I said:
1 hour ago, Stuart Weenig said:In the meantime, all you need to do is create a virtual datapoint on the custom graph and specify your percentile parameters there.
Within a graph definition, you can create a "virtual datapoint" that gets calculated at runtime. You would need to look in the definition of that graph to know which "real" datapoint you're calculating the 95th percentile. Since i cheated by taking a peek, that graph is pretty messed up. The title is misleading and it isn't configured to do any percentile calculation at all. It just plots inBps and outBps. If you look at the legend, it looks like it was labeled "peak", which is also misleading since it does nothing to actually calculate anything close to a "peak" value.
Taking a step back: what do you want to accomplish here? Do you want 95th percentile? If so, i'd say modify this graph so that it uses a virtual datapoint to calculate that percentile value.
