Nagios stops checking after start


#1

I know nothing of Linux and very little about Nagios, I inherited the system for a tech who left.

Checks of hosts will be performed after a reboot of the nagios services approx 4 times, then it stops checking until the next restart

Also the services do not appear to have been checked for any of the systems for the last 3 days.

Running 3.1.0 and with NagiosQL installed also 3.0.3

HELP!

running /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg states no serious problems were detected


#2

first thing, stop nagios, check there are no leftover nagios processes (“ps -ef | grep nagios”) if there are kill the leftover processes. then start nagios.

See what happens :slight_smile:


#3

login as: root[root@idc-nagios01 ~]# service nagios stop
Stopping nagios: /etc/init.d/nagios: line 67: kill: (11911) - No such process
done.
[root@idc-nagios01 ~]# ps -ef |grep nagios

#4

idc-nagios01.local is the name of your server?

try starting nagios again and see what happens.

Thinking of it… Keep in mind that Hosts usually DO NOT get checked as long as services on the host respond, when the servoces fail nagios will check if the host is alive.


#5

After I restarted, made no difference, did the same thing.

Not sure if these will help ?

#6

Its named idc-nagios01 on our systems.

I have restarted it and reboot the actual server several times.

It checks the hosts 4-5 times, then stops checking and hasnt check the services on anything for the last 4 days


#7

If no service checks are executed check if active_checks_enabled is set to 1 in the hosts template you are using…
anything in the nagios.log file when it stopped checking?
Are the service checks being rescheduled?
could it be some template is using a timeperiod which doesn’t make sense?


#8

Nothing in nagios.log file.
