Version 3.0b2. We’ve set up several hosts and services. But we’re not receiving any notifications and I can’t figure out why. The service and host details all show “Last Notification: N/A (notification 0)”. The notify-service-by-email command works from the command line as the nagios user. I’ll try to include as many relevant config sections as possible below.<o:p></o:p> <o:p> </o:p> The box is CentOS 4.5 running Linux version 2.6.9-55.0.2.ELsmp.<o:p></o:p> <o:p> </o:p> There doesn’t seem to be any debug information for notifications, so I can’t tell if the notifications are being blocked by something I haven’t looked at. I wish there was a logging option that allowed me to audit the notification filters, or at least a “test notification” feature. (if these things are there, someone tell me where and I’ll admit I’m an ‘idiot’). <o:p></o:p> <o:p> </o:p> I appreciate any help that can be given.<o:p></o:p> <o:p> </o:p> From Contact.cfg:<o:p></o:p> <o:p> </o:p> define contact{<o:p></o:p> contact_name mdsouza_e ;
