Broker
Hello,
I am trying to use nagios-msg-broker-0.0.4 from

I unzipped plugin and moved to the the /usr/local/nagios/libexec directory
nagios-msg-broker.sh # file
config.xml #file
lib #directory
content of the nagios-msg-broker.sh file is
=================
#!/bin/sh
java -DnagiosCommandFile=/usr/local/nagios/var/rw/nagios.cmd \
-DconfigFile=./config.xml \
-jar lib/nagios-msg-broker-0.0.4.jar
==================
Content of the config.xml file is
=============

=============
When I login to nagios monitoring machine through the web,
All my other checks that I didn't mention here run fine.
For the above mentioned service, for mypc target machine, I see the following
Under column "service: dlg_Alerts_notifications
Under column "Status": Warning
Under column "Last Check": 03-27-2012 17:53:53
Under column "Duration": 0d 4h 2m 19s
Under column "Attempt": 3/3
Under column "Status Information": (null)
==============
Can you please provide me with information to how get rid of the (null) in the
"Status Information" column and get there meaningful data?
Thanks.
Mikhail.
