Good Morning (Or Evening), Recently I have been tasked with setting up a otrs install as our tier three ticketing system. We have a monitoring software called Intermapper that functions similar to nagios. I have been trying to get the SystemMonitoring module working with the emails that it (Intermapper) sends out. However I have yet to get it fully functional. I keep getting: SystemMonitoring Mail: SystemMonitoring: Could not find host address and/or state in mail => Ignoring in the logs. I have tried removing the Host address regex and using only the State regex as the emails coming out of Intermapper have the State in the subject line and not the host address. The regex I use for the states is pretty simple: Warning|Alarm|Down|Up|OK Please note that I also use OK|Up for the CloseTicketRegExp (Which doesn't seem to work ether). My question is: When I remove a line item (like the host address) from the SystemMonitoring -> Core::PostMaster area does it revert back to defaults and generate the error above because it can't find the host address? Or is my regex for the State the one still generating the error? Thanks for any help in advance, -Nick Peters
