Hi list,
We arecurrently monitoring 220 Host and 3000 services with NAGIOS 2.5 on
Solaris 8.The web server and the CGIs are chrooted, but Nagios core is out of
the jail.We use symlinks to ensure the communication between the CORE and the
CGIs.
We notice
that some hosts and services suddenly disappear on the web interface. According
to the FAQ, this is due to multiple main nagios process in memory.
We are surethat Nagios init script is run just once and then watch nagios
processes
Here is theresult:
-bash-3.1#ps -eaf|grep -i nagios.cfg|grep -v grep;echo;echo;echo
nagios

-d/usr/local/etc/nagios.cfg
Mainprocess id is 10334, and we see it forking frequently. Some childs fork
inturn, then die, letting orphan processes …
What aboutthose orphan processes staying in memory ? Is it Nagios’ normal
behaviour ? Doservices and host disappear suddenly because of this ?
Thanks foryour advices !
Regards
Xavier
