Folks So I have system monitoring installed but I cannot get it to acknowledge alerts on the Nagios side, which I need to be over HTTP. I have updated the configurations for system monitoring to include the DynamicField_ addition to the free text fields. I have updated the regex to capture the necessary service/server data, and confirmed that these are captured and recorded in the DB. I have updated the URL for Nagios server. I have updated the trigger to TicketOwnerUpdate, rather than TicketLockUpdate. When I update the owner on a ticket, the system doesn't even seem to try to acknowledge the alert. I don't see anything in the system log. I don't see anything in the httpd logs (either Nagios or OTRS servers), I don't see any errors. OTRS : 4.0.13 System Monitoring : 4.0.2 KIX4OTRS : 7.0.6 KIX Core : 4.0.5 I'm not sure what information would assist in trouble shooting this issue. It simply seems to not even trigger the 'I should send an acknowledgement to Nagios' event. If I paste the GET command into a web browser with a session authenticated to the Nagios server with the OTRS user/pass, it successfully processes the acknowledgement, so I think once I can work out why it isn't triggering, it should be good to go! Any direction or guidance would be great. Cheers Rob.
