NCSA stopped working

[vmesquita]

We have a few passive checks, and apparently NCSA stopped working. I can see the entries on the log, for instance:

Code: Select all

Jul 26 18:47:51 nagios xinetd[32620]: START: nsca pid=10191 from=::ffff:172.27.164.29
Jul 26 18:47:52 nagios xinetd[32620]: EXIT: nsca status=0 pid=10191 duration=1(sec)

However the state of it the check hasn't changed for over 1 hour.
I have already restarted xinetd and rebooted the Nagios Server, with no changes.

NSCA is running via xinetd, hence xinetd will log those entries every time inbound NSCA traffic is received.

Are you seeing any entries in the nagios log? /usr/local/nagios/var/nagios.log

This KB article will show you how to enable debug mode for NSCA to watch what is happening:

https://support.nagios.com/kb/article.php?id=83

What client are you using to send the NSCA check results?

I enabled the debug, this is a sample output in /var/log/messages:

Code: Select all

I don't see the entries in nagios log, however.

Are you seeing them in Admin > Unconfigured Objects? The exit code is zero so it should be working.

Just to make sure that the command file is setup properly, please send the output of these commands:

Code: Select all

ls -ld /usr/local/nagios/var/rw
ls -l /usr/local/nagios/var/rw

Are you seeing any related errors in your /var/log/httpd/error_log or /var/log/httpd/ssl_error_log (if using SSL)?

Thank you

Hi ssax,

We open a support call and the nagios.cmd had wrong permissions, because of an issue in /usr/local/bin/snmptraphandling.py . Now it's fixed. Thanks!

Great to hear! Mind if we close this up?
