While developing zabbix templates on productive systems it´s often difficult to debug non working triggers.
If i increase the debug level to "4" (i.e. this is often needed to find the cause of a nonworking snmp item) my log is flooded with tons of messages.

It would be a cool thing to have a "debug-level" option on item level.
Increasing the debug-level to "4" on a certain item, should cause zabbix to log debug information at the place where the check is performed.
