Nagios 2.10, CentOS 5 x86_64 / i386, NDOUtils 1.4b6 Hi all,
I've noticed something odd wrt flapping, and am wondering if I'm overlooking something simple, or just misunderstanding the way flapping and state retention are supposed to work. First, just to verify, my main nagios config has: enable_flap_detection=1 retain_state_information=1 state_retention_file=/var/log/nagios/retention.dat retention_update_interval=<1,5,60 or even 0, doesn't matter> use_retained_program_state=1 use_retained_scheduling_info=1 In my global host and service templates that all hosts use, I have: flap_detection_enabled 1 retain_status_information 1 retain_nonstatus_information 1 I've also disabled flap detection explicitly for a few hosts, and it all works as advertised. However, for any host/service, if I manually disable/enable flap detection via an external command / cgi, and then reload or restart, the option reverts to whatever is in the config for that given host/service. This happens regardless of whether 1) the option is being set in retention.dat, which it is, 2) the NDO-fed database thinks flapping for this host/service is disabled, or 3) w/out the broker_module enabled. Other state options are being preserved (such as active_checks_enabled) both at retention_update_interval and on a reload. So, what I think I'm seeing then is that during a reload, the flap_detection_enabled option isn't getting read from the retention file at program start, though I'd expect it to be persistent just as the other options are. FWIW, same behavior on earlier Nagios 2.x releases, but 1.x seems to do the right thing. Before I dig further, can anyone verify that the state of host or service flap detection (enabled/disabled) should or shouldn't be persistent across a reload/restart? I've combed the docs and archives, and am coming up dry.
