[Nagios-users] Missing notifications?
I've just finished a fresh install of nagios, and for some reason, I get emails about acknowledgments of problems, (i'm rebooting servers to test how long it takes for the notification to come through), instantly, but I'm not actually getting emails about the problems?! I've checked the configuration via the nagios web interface, and the correct email address is listed. Is there more than one place to configure notifications to an admin? I'm finding this a touch disturbing, and I'm hoping that it's because I've got a misconfiguration in the system, rather than some sort of default behavior. I would pretty much want to be notified instantly every time there is a problem, at least until such time that I can find problems with my systems fix them, and then tweak notifications as required. I guess the bottom line is, why are acknowledgment emails being sent, but not warnings, and criticals? -- Learn how Oracle Real Application Clusters (RAC) One Node allows customers to consolidate database storage, standardize their database environment, and, should the need arise, upgrade to a full multi-node Oracle RAC database without downtime or disruption http://p.sf.net/sfu/oracle-sfdevnl ___ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null

I was directed in the irc forum to look at http://nagios.sourceforge.net/docs/3_0/statetypes.html and I learned that services or hosts need to have a hard state failure, in order for notifications to go out. I've been trying to reboot my servers in order to get my notifications to go out. I'd like to check that I'll actually get notifications as soon as there is a problem, for example, a host goes offline, I'd like to know after about 2 minutes if possible! Then just turn a server off and wait a bit... ;-) You could also create a fake host, one with an unpingable IP address. As for how much time it takes to notify once the host/service becomes unresponsive, these three definitions (outside of any separate escalation policies) will dictate how fast the first alert will go out: max_check_attempts normal_check_interval retry_check_interval In your case, you'd probably want to set max_check to '2' and normal and retry to '1'. In this case, assuming interval_length=60, the host (or service) would be checked every minute. When the host becomes unreachable/down, the host would then be rechecked once, one minute after it first becomes unreachable/down. If it was still down, the state would then become 'hard' and an alert sent. Total time before alert was sent could be anywhere from 61 seconds to two minutes, depending on when the host is first checked after it goes down. You really need to read the object definitions in the Nagios documentation. -- James Moseley -- Learn how Oracle Real Application Clusters (RAC) One Node allows customers to consolidate database storage, standardize their database environment, and, should the need arise, upgrade to a full multi-node Oracle RAC database without downtime or disruption http://p.sf.net/sfu/oracle-sfdevnl___ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null

My favorite trick, that doesn't require adding fake config or rebooting a server, is updating /etc/hosts on the monitoring host to point a real host at a known bad ip address. Requires root, and that you use dns for your hostaddress entries, however. -- Mike Lindsey -- Learn how Oracle Real Application Clusters (RAC) One Node allows customers to consolidate database storage, standardize their database environment, and, should the need arise, upgrade to a full multi-node Oracle RAC database without downtime or disruption http://p.sf.net/sfu/oracle-sfdevnl___ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null
