I’ve performed a clean install of libreNMS on Ubuntu 22.04
I’ve then migrated the database over from a libreNMS Centos 7 install and copied over rrd files.
Unfortunately the rrd files don’t appear to be getting updated when I enable rrdcached. Note. Disabling rrdcached and everything is OK.
Running poller.php on a device doesn’t rectify this either. If I erase rrd/DEVICE folder then run poller.php on said device, it will create the folder and files. However, it doesn’t continue to update. Similar happens if I add a new device.
Polling is definitely happening as device alerts etc are updating.
I’ve set permissions and confirmed.
chown -R librenms:librenms /opt/librenms
chmod 771 /opt/librenms
setfacl -d -m g::rwx /opt/librenms/rrd /opt/librenms/logs /opt/librenms/bootstrap/cache/ /opt/librenms/storage/
setfacl -R -m g::rwx /opt/librenms/rrd /opt/librenms/logs /opt/librenms/bootstrap/cache/ /opt/librenms/storage/
chown librenms:librenms /var/lib/rrdcached/journal/
Am I missing something obvious?
