NagiosXI and Highcharts dynamic scaling

[krobertson71]

I have brought this up before. We have several people complaining about how highchart behaves when things like CPU Percentage and Memory Percentage hit 100%. The Highchart graph automatically increases the graph to 150. When members of IT are showing management two chart comparing CPU between hosts, one will be 0 to 100 due to only being at 75% but the other one will be 0 to 150 due to being at 100%. Visually this is hard to display to managers. They are constantly having to explain away the difference as visually they look like they are at the same, or near, level as they are not looking at the axis in the report right away.

Here is an example:

You can see the white space and how the graph data does not exceed 100%.

We are using the NCPA agent and monitoring CPU, Memory, Disk, etc.. by percentages.

Other than in-house development, which is something I really dont' want to go back to management with, is there anyway someone can help me correct this behavior?

As implemented our highcharts features are pretty static. They can probably be changed, but it would be a feature request.

I'd be happy to put that request in but it's not very likely to make it into the next major release that's coming up; it's just too close to time and not a big enough feature.

If you could that would be great!

Maybe some kind of control of the graph you are looking at where you could just set the floor and ceiling. I know those are variables you can set as they are documented on highcharts website. But when looking at Nagios XI's highcharts.js I am like.. not going there.

Thanks for submitting that for me and you can close this ticket.
