Graphs shows no data - Observium

Probably cron does not work.

Manual recommends using these:

33 */6 * * *   root    /opt/observium/discovery.php -h all >> /dev/null 2>&1
*/15 * * * *   root    /opt/observium/discovery.php -h new >> /dev/null 2>&1
*/15 * * * *   root    /opt/observium/poller-wrapper.py 2 >> /dev/null 2>&1




it will not work when edited using crontab -e

Create new file in /etc/cron.d/observium

and paste there.

If still does not work try this:

33 */6 * * *   root    cd /opt/observium/ && ./discovery.php -h all >> /dev/null 2>&1
*/15 * * * *   root    cd /opt/observium/ && ./discovery.php -h new >> /dev/null 2>&1
*/15 * * * *   root    cd /opt/observium/ && ./poller.php -h all >> /dev/null 2>&1

If still does not work, try to add above cron entries into

/etc/crontab


and restart cron service.
