I recently migrated librenms to a new server. I copied over the rrd/ and permissions seem to look good. The problem I have been having after the migration is no data is being displayed on the device graph. I get the “No data” instead of a graph. I ran the RDD command and I get the following error.
“ERROR: opening ‘/opt/librenms/rrd/172.18.10.16/availability-86400.rrd’: Permission denied”
Below are the current permissions.
-rwxrwxr-x. 1 librenms librenms 125000 Oct 4 11:20 availability-86400.rrd
[librenms@S-MCSOS-LibreNMS ~]$ ./validate.php
