[Nagios-users] host down -> flapping -> host up -> no host up notificatoin

[Ralf G. <Ral...@Ra...>]

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
