Nagios Unable to Generate Availability Logs

Rudra · May 2, 2005, 6:09am

Dear all,

The Nagios nettwork monitor at my site, which basically monitors the leased lines, has of late, stopped generating host log enteries and as such we are unable to determine the uptime and the downtime (or Availability) of a particular link.

The host log entries show the following:

Event Start Time Event End Time Event Duration Event/State Type Event/State Information
04-19-2005 00:44:23 04-19-2005 10:42:53 0d 9h 58m 30s HOST UP PING OK - Packet loss = 0%, RTA = 26.53 ms

Any help on this would be highly appreciated.

Thanks

Hi,
nagios stop by itself ?
Or did you restart it ?

If not, try to see why it stops. Perhaps when it try to check a particular service or host ?

use /etc/init.d/nagios stop and not a kill.

Hi Guano,
Thank you very much for your reply. I just did as advised by you, plus I will also look out for other probable reasons, which might be culpable for “Abnormal Program Termination”.

Thanks again…I really appericate your help.

Have a nice day!

Post the output of the following:
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg please.

Hi J,

I am sorry, i couldnt come, as I was busy with other work and stuff. As advised Guano, I did what he had suggested. Though the program doesnt terminate and start that frequently, still Nagios isnt generating uptime/downtime logs.

Anyway, here is the output of the command you asked for:

Nagios 1.2

as Ia m not very well versed with Linix, so please pardon me for any stupidity or idiosyncracy on my part.

Thanks so much.

Perhaps nagios isn’t even making any checks. Are active checks enabled?

Guano · May 13, 2005, 7:57am

Here are another things to do, I hope it can help you:

Check how many nagios are running : "ps -e | grep nagios"
There must be only one.
See syslog : "more /var/log/messages"
Pershaps nagios has written why it stopped this way.

Good luck
