After posting this , I found there is some role of lock file , ndo2db.lock , nagios.lock ,, I don't know what was the last value but currently showing
more /usr/local/nagios/var/nagios.lock

The lock file contains the PID, try restarting nagios:

Code: Select all

service nagios restart

If that happens with the others I would restart them as well.

Not sure how that could have occurred though, this is the first I've seen it.

Thanks ssax

as per your hint, checked and found he did => /etc/init.d/nagios restart

before closing, can you please explain what is difference between /etc/init.d/nagios restart AND service nagios restart

They are essentially the same thing. service just has some additional steps involved related to consistency:

Dear Expert

ls -l /usr/local/nagios/var | grep -i nagios.lo
-rw-r--r-- 1 nagios nagios 5 Jul 30 14:51 nagios.lock
-rw-r--r-- 1 nagios nagios 0 Aug 2 03:42 nagios.log
-rw-r--r-- 1 nagios nagios 969425 Aug 2 10:57 nagios.log-20150802

Today again it happened (new nagios.log file is 0 byte not updating), I did not do any service restart instead did Applied Configuration and okay. Looks it will happen again every week (Sunday). Why? Any solution?

-bash-4.1$ ls -l /usr/local/nagios/var | grep -i nagios.lo
-rw-r--r-- 1 nagios nagios 6 Aug 2 10:59 nagios.lock
-rw-r--r-- 1 nagios nagios 39734 Aug 2 11:20 nagios.log
-rw-r--r-- 1 nagios nagios 972031 Aug 2 10:59 nagios.log-20150802

merged two files (work around solution)

cat nagios.log-20150802 nagios.log > nagios.log
cat: nagios.log: input file is output file

What specific version of XI are you running? You can grab it from the bottom left hand side of the XI web interface.

Can you post the nagios.cfg?

[ssax]

Do you have anything configured for nagios in /etc/logrotate.d or /etc/logrotate.conf? If so, please attach the files. Also, please attach a sanitized copy of your /usr/local/nagios/etc/nagios.cfg.

[tgriep]

Could you run the following and post the output so we can get the settings for logging?

Code: Select all

 grep log /usr/local/nagios/etc/nagios.cfg
