Nagios Support Forum

Have the VM of Nagios.

The performance graphs have not worked since upgrading to R2.0. Is there a way to fix this or downgrade to 1.8? 1.8 worked great but I figured it was time to upgrade and now the performance graphs do not work.

Thanks,
Kent

What results are you getting for the performance graphs? Blank page, continuous spinning processing?

The graphs were going fine until the upgrade and now the data just looks like it stopped for example the CPU of one of the servers nagios is monitoring is always around 20-30 percent and now there is no graph data just an empty graph.

As I read through more posts in the forum I found out I think it is the same issue with the sourceguardian not installing right. I cannot figure out how to fix it though.
I get this when trying to upgrade again. No valid Sourceguardian extension found for PHP version 5.1

Thanks

Here is what the graph looks like now:

Can I have you verify that npcd is running And then also look at the following and

The npcd service is running. The npcd.log looks like this

Thanks again,

After searching for solutions, I looked back and figured I should look at the log again. So I found out what error 126 does and found it was a permissions error. I set the permission on process_perfdata.pl to be able to be executed and it started working again. Even caught up with all of the time it was off.

Thanks for leading me in the right direction and maybe this will help others,
Kent

Thanks for the follow-up, we'll have to make sure to add that to our FAQ for performance graph issues.
