In this Version the Plugin doesn#t provide any perf data

On Icinga 2 this check does not provide any per data, because of wrong Perf data output format.

To fix this it is required to change the line from
perfdata = ‘ActiveConn:%s,reading:%s,writing:%s,waiting:%s’ % (ActiveConn,reading,writing,waiting)
to
perfdata = ‘ActiveConn=%s; reading=%s; writing=%s; waiting=%s’ % (ActiveConn,reading,writing,waiting)

This works for me to get it working for icinga 2.
