Hi,
I'm having a problem with the graphs of all my devices in observium (screenshots attached). What is the advisable crontab settings should I use given the list of devices I am polling?
Just follow the manual
Crontab settings: */10 * * * * root /opt/observium/poller-wrapper.py 1 >> /dev/null 2>&1 */10 * * * * root /opt/observium/poller.php -h all >> /dev/null 2>&1
This will not work. RRD will think it is missing data if you only poll every 10 minutes. And polling every device twice every ten minutes is not the same as polling every 5 minutes. Start with what the manual tells you:
33 */6 * * * root /opt/observium/discovery.php -h all >> /dev/null 2>&1 */5 * * * * root /opt/observium/discovery.php -h new >> /dev/null 2>&1 */5 * * * * root /opt/observium/poller-wrapper.py 1 >> /dev/null 2>&1
And then increase the number behind poller-wrapper.py to run more pollers in parallel.
Cheers, Sander
