Nagios v2.9 disappearing hosts/services

[Steven Haigh]

Replying to myself again...

Interestingly enough, it seems that this error seems linked to the
number of failures of various services/hosts. I haven't managed to pin
out a number as yet, but I can replicate it by adding a dud config file
with 20+ services that will always fail (ie become critical). After
doing this, I always lose hosts from the Service Detail page.

Removing the config file and restarting Nagios makes the problem go
away. Enabling it, and the hosts go missing again.

Is there any way I can debug this further?

 Hi again all,

I am still having an issue with disappearing hosts from the nagios
service detail page. The summary shows:

Ok 	Warning 	Unknown 	Critical 	Pending
206	10		13		48		6

All Problems 	All Types
71			283

However, on the service detail page, only 14 services across 4 hosts are
displayed.

There is only one nagios process running:
# ps -lAF | grep nagios
1 S nagios    7141     1  0  80   5 -  6135 stext   5220   0 15:31 ?
00:00:00 /usr/sbin/nagios2 -d /etc/nagios2/nagios.cfg
0 S root      8851  5904  0  78   0 -   413 pipe_w   512   3 15:36 pts/0
00:00:00 grep nagios

I can't find anything via google or the FAQs etc that may explain this.

Does anyone have any ideas on this?

Hi all,

We're trying to upgrade our nagios monitor from v1.1 to v2.9, however
I'm having problems with hosts disappearing from the service details.

If I stop nagios and remove the state retention file, then restart
nagios all hosts appear again until the status checks start going - at
which point hosts disappear again.

There is only one nagios process running (as per the FAQ). Without
removing the retention file, the host list will still be missing a lot
of hosts.

Verifying the config using nagios2 -v does not show any errors.

Does anyone have any ideas what is going on here?

Regards,
Steven Haigh
