Hi, 
we are monitoring the reliability of WAN lines. We have a check, which measures the round-trip-time to a remote site and giving back the min, avg and max RTT.

I’d like to have a graph, which draws the avg as a solid line (that’s easy) and I want to have the area between the min and max filled with a colour. For those, who know smokeping, I like this kind of display a lot!

Maybe there are other use-cases, where a filled area between two metrics might be useful !?

Would it be possible to fill the max metric as usual and restore background colour (erase the filling of the max) with the min metric?

For a better understanding, I’ll add some screenshots here.
We used smokeping in the past (maybe somebody knows that) and our colleagues really like the way, this little tool delivers information (RTT and packet loss from 10 ping probes per minute => one ping every 6 seconds).
Here is a screenshot from smokeping:

Now we want to cover the same information with Centreon and we’ve created a script, which does also 10 ping probes per minute. We just use the best RTT, the worst RTT and the average RTT, which are the most meaningful (and packet loss in addition).

With the line-graphs only it’s not that nice and good to read.
Zoomed into the old smokeping, it’s better to see, what I mean:​​​​​

 

The light-to-dark grey area highlights the range, all 10 probes are in.
The coloured line marks the average for each minute.
By showing it that way, everyone understands, that this is the range for RTT you have to deal with.
​​​​​​Hope to find someone with similar needs.
