[Nagios-users] Help with failover
I have 2 master servers that attach to a shared NAS which holds the nagios configs and status data basically /etc and /var. When the primary goes down there's an event handler that mounts the NAS on the backup and starts nagios. When I implemented this setup I thought it would be beneficial in the sense that I would have all the status data retained from the primary instance. This is not the case when I initiate a failover the backup system which mounts all the same data that the primary had prior to being brought down doesn't see any saved status data all checks are in a pending state until the distributed servers send new check data via nsca. The other confusing thing is that if I fail it back over to the primary it see's the old saved status data. I'm not sure what I'm missing here can anyone enlighten me?

[Nagios-users] Issues with Nagios 2.4?
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Nagios seems to have been very unstable the past couple of weeks. The only change I've made is upgrading from 2.2 to 2.4.

In general, since upgrading to 2.0 Nagios seems very slow on catching broken services/hosts, but usually checks them (not always).

Re: [Nagios-users] Issues with Nagios 2.4?
Here's my Nagios log without comments or blank lines snip service_inter_check_delay_method=n snip host_inter_check_delay_method=n Try using a setting of 's' for these two directives. Using no delay is generally not recommended. -- Nagios Documentatio These are some parameters I've been fiddling with. There is no difference when I use =s versus =n, it's consistently unreliable no matter what I try. Next, look at your scheduling queue for clues (note that host checks will not be 'scheduled', only service checks get shceduled) Well, I do notice that most of my schedules checks are in a past-time, and I have to assume that they're just not getting run. Finally, if there are a very large numbers of hosts in down/unreachable state, they can affect your service check performance severly. --- BitPusher, LLC http://www.bitpusher.com/ 1.888.9PUSHER (415) 724.7998 - Mobile Using Tomcat but need to do more?

How is your host defined exactly? What do you see reported in the log
