I was strugeling with macro's in zabbix items always returning the wrong value 0 instead of 1 when i was checking some ports with net.tcp.port[

,22]
after some testing i found out that it was a active agent issue. Digging in the issue deeper i found out that zabbix is only suporting it since 2.0.3 in passive items

"Since Zabbix 2.0.3, the HOST.* macros supported in item key parameters will only work in item types that have interfaces, i.e. they will not work for types "Zabbix agent (active)", "Calculated" etc."

we are now in 2.2 and this is still not fixed it's a half baked implementation that should work for active and passive
yes it was documented and yes i should have read the small notes but ARRRCH ! i don't want to use passive active passive active again it should just work for active as wel or at least give me a "not supported" status instead of wrong values !!
