Karl, I have re-posted to nagiosplug-devel at list.sourceforge.net for some
fuller discussion.
I do have one comment. Sending a string as a metric value is not
something the protocol supports. I also believe the aim of this
protocol is to storing numerical performance data. Which can be
imported to PP or RRD. I am not sure that passing a string is a good
idea. No plugin currently does this. Can you explain further why you
would want to pass a string as a performance metric value?
Regards, Ben.
