Hi, I use the nagios flap detection feature. Last week I got a host down notification, I was not in the office, so I waited a few minutes for a host up notification, but I got none. Then I asked a colleague by phone what the state of this host really is. The host was up and ok. Next day I discovered the flapping message in the logfile, the host state was down and then changed to the flapping state. I found the following about flap detection in the docs: |1. Log a message indicating that the service or host is flapping |2. Add a non-persistent comment to the host or service indicating | that it is flapping |3. Supress notifications for the service or host (this is one of the fil= ters | in the notification logic) | |When a service or host stops flapping, Nagios will do the following: | |1. Log a message indicating that the service or host has stopped flappin= g |2. Delete the comment that was originally added to the service or host w= hen | it started flapping |3. Remove the block on notifications for the service or host (notificati= ons | will still be bound to the normal notification logic) If I understand this right, there is no way to get a host up notification= , if the host was down at moment the flap detection happend? That's a bit anoying, especially when you are not in the office. I took a quick look at the nagios 2.x docs | Flapping notifications - Notifications are now sent out when flapping | starts and stops for hosts and services. This feature can be controlled | using the f option in the notification_options for contacts, hosts and | services. Is there any way to realize this with nagios 1.2? Maybe and existing patc= h? If not, is nagios 2.0b1 (still called beta release) stable enough for production environment? How complicated is an update from 1.2 to 2.0b1, especially the config fil= es? TIA Ralf |
