NSCA Distributed Server

[Jeff Engstrom]

Marc,

	First and foremost, Thanks for the response!

	I was unable to locate anything strange when I did a tail -f
/var/log/messages on either machine.

	Thanks for the heads up on the command_check_interval setting.  That
was there for testing and I forgot to change it back.

	I'm not sure why the oscp_command is not executing on the
distributed server when the configuration tells it to execute?? 

	One strange thing to note though...  If I run the script manually
from the distributed server it connects for 10secs and then times out.  This
is the output of /var/log/messages on the central server...
		Dec 17 13:20:44 nsca[6650]: Handling the connection...
		Dec 17 13:20:54 nsca[6650]: End of connection...

Thanks again!
Jeff

Greetings,

            For some reason the script that updates the central server is
not executing but all other external commands seem to work fine.  I was
hoping that someone might be able to help?  Here is the configuration (sorry
about the length)...

<MARC> - Is there any error message in /var/log/messages on either machine?
You might try enabling the debug option in nsca.cfg to get more detailed
information. You should also try submitting a check result by calling
send_nsca manually. That might spit out some errors. I'd also verify that
nsca is listening on the IP/Port you expect it to be via netstat -aelp.


Central Server (10.1.1.4)
            NSCA running in daemon mode with the following config...
                        server_port=5667
[snip]
<MARC> NSCA config looks fine at first glance.
            
            nagios.cfg has the following..
[snip]

command_check_interval=30s

<MARC> - This isn't valid for a 1.1 or below config AFAIK (it may be for a
2.0 config though). This should be an integer value specifying a multiple of
the interval_length. For example, if you have your interval length set at 60
(seconds), then a 1 here would cause nagios to check for external commands
every 60 seconds. 2 would mean every 120 seconds. The only odd value you
could have here would be -1 which would cause nagios to check for external
commands as often as possible. This could very well be your problem. A
simple test would be to do an ls -l on rw/nagios.cmd and see if it's
anything other than 0 length. If it's not then NSCA is successfully
appending new results to the file but nagios may not be reading them.

Distributed Server (10.1.1.3)

[snip]
<MARC> Distributed server information looked fine. It is interesting to note
that your had the command_check_interval set to -1 here where I would expect
the least number of external commands (if any) to be received. That's more
of a work-flow thing anyway I would suspect.
