I Believe this is related to this bug report
https://github.com/nagios-plugins/nagio ... issues/235

And will be released in the 2.2.2 version of the plugins when they come out

Got it ... how will upgrade to the next version

I believe the next plugins release may be coming out in the next several weeks and the integration in XI will follow that.

done ... please close the ticket
