Hi all,

I have taken over an Observium install and am trying to get it back up and running since most of the new devices are not in it. Every device I add I have to manually run the discovery and poller. I have checked the txt file in /etc/cron.d/observium and it reads:

# Run a complete discovery of all devices once every 6 hours 33 */6 * * * root /opt/observium/observium-wrapper discovery >> /dev/null 2>&1

# Run automated discovery of newly added devices every 5 minutes */5 * * * * root /opt/observium/observium-wrapper discovery --host new >> /dev/null 2>&1

# Run multithreaded poller wrapper every 5 minutes */5 * * * * root /opt/observium/observium-wrapper poller-wrapper.py 10 >> /dev/null 2>&1

correct entry here should be:

|# Run multithreaded poller wrapper every 5 minutes */5 * * * * root /opt/observium/observium-wrapper poller >> /dev/null 2>&1 |

# Run housekeeping script daily for syslog, eventlog and alert log 13 5 * * * root /opt/observium/housekeeping.php -ysel >> /dev/null 2>&1

# Run housekeeping script daily for rrds, ports, orphaned entries in the database and performance data 47 4 * * * root /opt/observium/housekeeping.php -yrptb >> /dev/null 2>&1

Is it just a matter of creating this text file in this folder and it automatically runs or am I missing a step to get it to run every 5 mins etc.
