Hi ,
Sorry for late reply.
Actually I have already upgraded to 5.3 in the middle of troubleshooting this issue. Having that said, extending mysql character, new utilsx.inc.php are all done under nagios 5.3.3.
This was actually identified as a bug in Nagios Core which was fixed in 4.2.4. It was impacting other plugins as well, not just check_nwc_plugin. The bug fix should be included in Nagios XI 5.4.0.
Nagios XI 5.4.0 should include a more modern version of Nagios Core, as well as the mentioned fix. We're looking at a January release currently (subject to change).
