Doesn’t seem to support Nagios 3.x multiline results

This plugin works fine for me, except that it doesn’t seem to support check-plugins that outputs multiline results. This is a new feature in Nagios 3.x from what I can tell.

I have one of those in my setup, check_jmxeval, that does two tests at the same time. The output is like this:

JMXEval CRITICAL – 2 checks, 1 critical [Threads], 1 ok
[1] Threads CRITICAL – ThreadCount is 73
[2] PeakThreads OK – PeakThreadCount is 73 | threadCount=73;150;100 peakThreadCount=76 time=0.0s

All that is returned to my Nagios server after this script generates the XML-code and sends it is the first line, like this:

JMXEval CRITICAL – 2 checks, 1 critical [Threads], 1 ok

I would like to see support for multiline output implemented in this script in the future. Right now I’m looking for a work around for this problem.
