Performance Graph-No data found

[lanxessinfy]

Hi team,

We are using check_nrpe plugin to check the disk space.

Plugin:
./check_nrpe -H 10.25.11.3 -c check_drivesize -a drive=C: 'warning=free<10G' 'critical=free<5G' show-all 'perf-config=*(unit:G)' detail-syntax='{${drive_or_name} ${free} free / ${size} total}' top-syntax='${status}: ${problem_list}'

And when we are pulling report we are unable to get the performance graph. It is showing No data to display.
Please find the attached image

.

Please help us with this.

Note:
Intially we have used check_nt plugin where we used to get the performance graph but As per business requirement we are using checks based on specific value so we are using above plugin currently

Thanks & regards
Vamshi

Try renaming the backend RRD file, this usually occurs when you change the plugin and the number of metrics changes:

Code: Select all

cd /usr/local/nagios/share/perfdata/THEHOSNAME
mv THESERVICENAME.rrd THESERVICENAME.rrd.old

Then force a check, wait 15 minutes, and check again.

If that doesn't resolves it, please follow this KB to debug:

Hi,

Thanks a lot.
Now we are able to fetch the performance graph.

That's great to hear, let us know when we're okay to lock this up and mark it as resolved.

Thank you!

Also we have another problem.

we are unable to download the reports even though we have admin access.

Hi,

My apologies for the inconvenience, can you re-send those files to my account. Sean is out of the office today.

In the meantime, I believe you are hitting PHP limits and that's preventing the reporting from completing. Please follow the steps in the KB article below and let us know if the issue is resolved.

Hi,

Thank you for the files, the profile looks good. Please edit the /etc/php.ini file, and change the following values to:

Code: Select all

max_input_vars = 50000
memory_limit = 1024M
max_execution_time = 120

Then save the file and re-start httpd

Code: Select all

systemctl restart httpd

See: https://support.nagios.com/kb/article/n ... e-611.html

Then test the report once again as both the nagiosadmin account and a user account. If it fails please attach the PDF to the ticket.

Thanks, Benjamin
