LibreNMS doesn't graph jitter using check_icmp plugin


I hope you’re doing well.
I’m trying to use the plugin check_icmp to graph jitter, but when I try to do it the LibreNMS shows the following error (Error Drawing Graph: ERROR: No DS called ‘pl’ in ‘/data/rrd/’):

The service configuration in the “Add / Edit Service” menu is “-J 40,50 -H”.
The output of the check_icmp service is:

librenms:/usr/lib/monitoring-plugins# ./check_icmp -J 40,50 -H
OK - jitter 0.074ms|jitter_avg=0.074ms;40.000;50.000;0; jitter_max=0.283ms;;;; jitter_min=0.001ms;;;;

I’m using the LibreNMS docker version:

/opt/librenms $ ./validate.php

I don’t know if I’m missing some configuration.

I’m looking forward to your feedback.

Anyone? Please, I need to graph this information.

Thank you.
