When an item becomes unsupported then generally something is going wrong with the server and I want to receive notification. Preferably unsupported items show up with a different color in my overview. However it would already be a big help if I can somehow create a Zabbix trigger monitoring Zabbix if any items became unsupported! I don't understand why by default Zabbix is not warning about these items since people can disable items that should not be used.

I managed to create a trigger to tell me when Zabbix has unsupported items using:
UserParameter=zabbix.unsupported,mysql -uroot -pPASSWORD -e "use zabbix; select * from items where status=3;" | wc -l
It returns the amount of unsupported items (0 means none). But this seems like an ugly "fix" for my issue. -

Another trick is to force the output of Userparameters to be integers (or output 99999). Just add at the end:
| sed 's/ //g' | grep -o [0-9]* -m 1 || echo 99999Comment
