Librenms Stoppped Plotting Graphs

Hi Everyone,

  • The output of `./validate.php


Component Version
LibreNMS 21.2.0
DB Schema 2021_02_09_084318_remove_perf_times (199)
PHP 7.4.16
Python 3.6.8
MySQL 10.1.48-MariaDB
RRDTool 1.4.8


[OK] Composer Version: 2.0.11
[OK] Dependencies up-to-date.
[OK] Database connection successful
[OK] Database schema correct

Poller still working
discovery still works
no errors on any of the logs

but graphs stopped plotting after I upgraded to php7.4 from php7.2 and installing python3.

I dont know where to look as I cant find any errors just graphs stopped plotting.

BTW, asked me to migrate the db and I said yes to it, not sure if its related but extra information.

please hlep help help


have you checked the output of running a single poller?

e.g: sudo -u librenms /opt/librenms/poller.php -h 1 -d

this should also tell you the output of the RRD commands if its maybe a permissions issue

Hey Simon @si458

yes, I have checked it works no errors nothing there.

btw graphs are all ok now. I didn’t do anything and after 9 hours it fixed itself.

no idea what was going on but I think my librenms is cooked.
