Hello.
Some of our graphics, using nagios grapher (1.7.1) is just not graphing some services in some hosts (the graph is working for the same service in other hosts) and some of them are just showing a lot of gaps.
What can be causing this and how to diagnose it?!

Re: nagios_grapher failing and showing a lot of gaps
It's best you contact the developer of this project to diagnose these problems.
Perhaps see what's in the httpd error log:
Or you could use rrdtool with the fetch argument to see if the .rrd files actually contain data.
Perhaps see what's in the httpd error log:
Code: Select all
tail /var/log/httpd/error_log

RDD is being updated.
We have the following errors in /var/log/httpd/error.log

We are using the version 1.7.1.
Any idea?

Re: nagios_grapher failing and showing a lot of gaps
As tlea suggested, we do not create nagios_grapher, and very minimally support it. I would highly suggest talking with the developer of the tool instead, as it looks like there is either a bug with your installation or with the version as a whole, it is impossible for me to know though.
Nagios-Plugins maintainer exclusively, unless you have other C language bugs with open-source nagios projects, then I am happy to help! Please pm or use other communication to alert me to issues as I no longer track the forum.
Re: nagios_grapher failing and showing a lot of gaps
Ok, thanks. I will try to find their forum.
