Restarting Nagios Client on OSX server

[cfgriffith]

As far as I can tell xinetd is not installed or running. There is no /etc/ config for it and I do not see it when I ps aux | grep xine

[tgriep]

Can you upload the log file that should be in the folder that you compiled NRPE in?
Maybe it didn't compile so that is why it may not be running.

[cfgriffith]

Here are the log files.

[jdalrymple]

what about `ps aux | grep nrpe`? I suspect it has to be running otherwise your errors would look a bit different. I wonder what the exact command being run is though - namely I wonder if it's loading the right config file.

The next step if that looks right is to spin up debugging in the nrpe.cfg:

Code: Select all

# DEBUGGING OPTION
# This option determines whether or not debugging messages are logged to the
# syslog facility.
# Values: 0=debugging off, 1=debugging on

debug=1

And then of course restart the daemon... then see what comes of it

[cfgriffith]

Marcomm-Server-MM-0487:etc admin$ ps aux | grep nrpe
nagios 39497 0.0 0.0 2460752 476 ?? Ss Thu09AM 0:02.84 /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
admin 45036 0.0 0.0 2432772 540 s000 S+ 1:57PM 0:00.00 grep nrpe


Yeah I see the process when I ps aux grep for it. Will restart the daemon in debugging and see what it finds. Although I was having trouble starting and stoping the daemon we'll see if i I have it this time.

[cfgriffith]

Okay I put it into debugging mode and restarted the daemon. Is there a log file I should give you guys from somewhere now after putting it in debug mode?

[jolson]

# DEBUGGING OPTION
# This option determines whether or not debugging messages are logged to the
# syslog facility.

Looks like the debug data will be sent to the system log. Try this:

Code: Select all

sudo cat /var/log/system.log

Well I think I found the problem sort of

But:

in /usr/local/nagios/etc/nrpe.cfg

allowed_hosts=127.0.0.1,140.225.8.240


8.240 is indeed our nagios server.


What other config file would it be reading from and where would I find it? I don't think it is xinetd because as far as I can tell it is not running. There is no /etc/ config for it and I do not see it when I ps aux | grep xine

[jolson]

Try removing localhost from the equation and permitting just the Nagios Server IP address. Maybe there's a bug with the comma delimitation?

[lmiltchev]

I don't think running:

Code: Select all

launchctl stop org.nagios.nrpe

will actually stop the nrpe process.

Try running the following commands:

Code: Select all

killall nrpe
launchctl start org.nagios.nrpe

then schedule a forced immediate check from XI to test it.
