Some Graphs working, some are not!

[danniiffxi]

Hi Forum

Back in November I built a new instance of Nagios, currently running 5.5.9 and core 4.4.3.

Now the problem I have is that some of the RRD graphs are populating, and others are not. for example our company uses a 10GB link between 3 offices for DR purposes, part of what we want Nagios to do is to monitor the Bandwidth utilisation on these links.

For example:

This one is working!




This one is not!




I should be seeing traffic on both, well I have actually have 2 working and 4 that dont but I am not going to post them all or it will take all day to read this, I just need to know how to get the graphs displaying 0.00 to populate with the correct figures.

The one thing I do know is that it is Nagios causing the issue somewhere, as I mentioned previously I have just built a new instance, our original Nagios graphs these without issue but we are moving to a new build and splitting our estate over two instances as it is to large for one instance of Nagios.

Would these Timeouts cause the issue?


I don't see it being an issue with RRD as all graphs are populating but some just with 0's rather than actual data. We have also logged directly into the switch and seen viewed live traffic which never made it over to Nagios.

Any help on this would be greatly appreciated, my boss loves pretty graphs, but not so much when they are empty!!

@danniiffxi, Please open the following cron file:

nano /etc/cron.d/mrtg

And delete --user=nagios --group=nagios at the end.
Then save the file and in the command line run:

service crond restart

Also, use this article to increase the following -> TIMEOUT from 5 to 40 and the load_threshold from 5 to 40.

Then run:

service npcd restart
