Nagios Support Forum

Hello Community,

I have a some configured services that have their graph's performance data not showing anything but "no data to display". I decided to delete and recreate them but it only worked partially. Nothing appears for most part of my servers from the monitoring of virtual memory usage and also for some different Windows drive check.

I found another post with a similair issue but renaming/deleting the corresponding service's rrd file doesn't change the situation even if no more errors are displayed for that service in the perfdata log when debugging is turned on.

I also looked at the troubleshooting steps on that page and everything is correct.

Any thoughts on that?

Regards,

Philippe

Thanks for reaching out @MEI-Nagios01,

Do you notice any errors in the php error logs? If you have php-fpm they should be in /var/log/php-fpm/www-error.log otherwise it'll be in /var/log/httpd/error_log.

Additionally, can you verify that the .rrd and .xml files exist in /usr/local/nagios/share/perfdata/[HOST NAME]/[SERVICE NAME].[xml/rrd]

Delete the .rrd and .xml measurement files.

Hello danderson,

Thank you for your reply and your help.

I only get warning notice messages in php-fpm logs.

Also, .rrd and .xml files live in the right path. Like I said, I renamed .rrd files and now no more errors are shown in /usr/local/nagios/var/perfdata.log.
Maybe I can try the xml files and see what it gives.

Indeed, I had to delete or rename both .rrd and .xml files. After that, performance data are back.

Thanks a lot!
