Decimals

[WillemDH]

Does Nagios XI cuts the decimals to three numbers after the comma in graphs? I'm working on a plugin to calculate link utilisation etc, but I notice the perfdata is sent correctly, but Highcharts seems to only show 3 numbers after the comma. Is this normal? Can it be changed?

This should work correctly, apparently it is not though. Off the top of my head, I would guess that it's actually either an issue with the pnp template assigned to your check, or rrdtool limiting the values provided(which I don't think is the case). Could you provide an example rrd we could test against and if it would be useful outside of your env a copy of the plugin to test against?

Edit: Also does switching to old style pnp graphs instead of highcharts change this behavior at all?

Hey Spenser,

I did not release this plugin yet. You can find in on my GitHub page here https://github.com/willemdh/check_ms_win_network_load
I have never changed anything in any pnp template. You might recognise some parts of the code by the way.. You can see there is only three decimals in the highcharts and five in the detail view.

The decimal is probably truncated for display reasons. You could always dump the rrd in question to see if the granularity is there:

Code: Select all

rrdtool dump </path/to/rrd>

If you don't using the rrdtool at the command line you could use this tool I created called the Perfomance Data Tool.

Troy, Already had your tool installed, but didn't used it yet to browse the rrd's yet. Very nice interface interface by the way!

So, as Andy said:

The decimal is probably truncated for display reasons.

In the rrd dump view, I can see the values with 5 decimals after the comma, so the graphs showing only three is expected behaviour?

Thanks for confirming.

Yes. If you need the decimal precision, open a feature request on tracker - the devs are cleaning up tracker as we speak, so it will get exposure.

Thanks Andy.

Made the feature request. I'm looking forward to next update.

Thread can be closed.

Closing thread. Next release will have a ton a fixes. But this feature request will probably not make the next release. Thanks.
