You can check the port that nodejs uses by developing a plugin. server side, checking port 3306:

#!/bin/bash

mysql3306=netstat -an | grep LISTEN | grep 3306 | awk '{print $4}' | sed 's/://g'

echo "<<<checks_ports>>>" if [ "$mysql3306" == "3306" ] then echo "3306 1" else echo "3306 0" fi

Then you need to do the checks on the server check_mk
