Nagios Support Forum

Hi,

We have an issue with some Nagios graphs that doesn't have any data to display.
I already checked the same service on a different host and it's properly accumulating data, and showing the graph.

I also already tried to delete that .rrd and .xml file for said service in the /usr/local/nagios/share/perfdata/pbv1monsql1

The files were recreated successfully and there is data in there, but it's still showing that there's no data to display when I attempt to check the graph.

I don't really see anything interesting in the perfdata.log, I see some timeouts but they are dated from a few months ago, and the timeouts were on all services of said host. The graph data is showing properly on all but 2 services on the same host, and those services are showing data properly on all the other hosts.

Do you know how to fix this issue ?

Regards,

Maxime

Hello Maxime,

Concernings log files, did you increase the data logging verbosity yet? There are two places in Nagios XI to set this.

1 Process Perfdata
/usr/local/nagios/etc/pnp/process_perfdata.cfg

Change LOG_LEVEL to Also, increase the TIMEOUT value to: 2. NPCD
/usr/local/nagios/etc/pnp/npcd.cfg

Change log_level = 0 to And increase load_threshold to: Once that is finished, let the server run for a while and then send us your system profile so we can review the logs. Thanks.

To send us your system profile.
Login to the Nagios XI GUI using a web browser.
Click the "Admin" > "System Profile" Menu
Click the "Download Profile" button
Save the profile.zip file and share in a private message and then reply to this post to bring it up in the queue.

Hi Benjamin,
Thank you for your reply, but it seems it won't be necessary after all.

I noticed that the graphs were gathering data successfully, I only needed to wait a bit longer (I waited around 45 minutes, but it took 1h before the graphs started to show)

Thank you and best regard,

Maxime

Hi Maxime,

Thanks for the update and happy to hear it's working.

I'll go ahead and close this post, but feel free to open another if you have any new questions.
