NSCA is not writing on log file(s)
Posted: Thu Feb 09, 2012 1:23 pm
I have an installation of Nagios3 on my Debian sever. I have followed several tutorials for that and is working ok (I'm monitoring a client successfully).
I have tried to implement NSCA to monitor certain processes, but I'm first testing it in the server (locally).
So, I have installed and configured NSCA in the server according to http://nagios.sourceforge.net/download/ ... _Setup.pdf and I have set a service in Nagios3 to listen in the localhost (the server).
A netstat shows:
I have created a file named "test" with the following content: "localhost TestMessage 0 This is a test message." (separated by tabs)
The problem is: when I send the command "/usr/sbin/send_nsca localhost -c /etc/send_nsca.cfg < test" in console, it returns: "1 data packet(s) sent to host successfully.". But there is no trace of it in /var/log/messages, and there is no trace of it in the web interface of Nagios3 (TestMessage: PENDING).
So, in the server, apparently NSCA is sending packets to the server itself, but they are not arriving.
Does anyone has an idea of what may be wrong?
Thank you all!
P.S: The server is running over VirtualBox
