Nagios upgrade from 3.5.0 to 4.0.8 issue

[kalyan1709]

Hi,

I have upgraded my Nagios Core 3.5.0 to 4.0.8.
After doing this I was not able to start nagios service. Also I can see "Unable to get process status" on the Nagios landing page.


# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

The warnings can be ignored, so let's check to see if the Nagios process truly is running or not:

Code: Select all

service nagios status
ls -l /usr/local/nagios/var/nagios.lock

Hi tmcdonald,

Thanks for the reply.

[root@nagios ~]# service nagios start
Starting nagios: done.
[root@nagios ~]# service nagios status
nagios is not running
[root@nagios ~]# ls -l /usr/local/nagios/var/nagios.lock
-rw-r--r-- 1 nagios nagios 6 Oct 10 06:49 /usr/local/nagios/var/nagios.lock
[root@nagios ~]#

Thanks,

I believe if you remove that file, nagios will start properly. The init script should look for that file as evidence of the Nagios process running, and if it is still there for whatever reason it may not start.

Hi tmcdonald ,

I have removed the lock file and tried starting Nagios service, But the no use.

Thanks,
KalyanP

[tmcdonald]

After you remove it and try starting Nagios, is it still there? Can you share part of the nagios log file?

Code: Select all

tail -20 /usr/local/nagios/var/nagios.log

Make sure to point that command to wherever your log file is.

I found the fix.

The nagvis is blocking my nagios service to start. As Nagvis is not compatible with Nagios Core 4.0.8, I removed Nagvis broker module fron nagios.cfg and my service is UP.

Thanks,
