Just tried alerts for internal events and I'm disappointed...

One of the reasons is that in Zabbix frontend (in "Info" column) I can see detailed and very useful info why item/trigger is not_supported/unknown.

But I cannot include this information in alerts and I must log into frontend to check what is wrong, while having such information directly in alerts I would be able to see that I could ignore such cases.

For example when Zabbix agent in maintenance I get internal alerts that all the "agent's passive" triggers became Unknown and I don't have any other details, while all the triggers have simply "Agent is unavailable." error message, which is not so serious.
... or when for just added item+trigger the trigger has error message "Cannot evaluate function "Zabbix server:agent.ping.nodata(5m)": item does not have enough data after server start or item creati"
(128 chars limit - trimmed)

I'd be happy to have macros like {ITEM.STATE.ERROR}, {LLDRULE.STATE.ERROR}, {TRIGGER.STATE.ERROR} and use them in corresponding action for internal events.
These macros can get information from database easily (column "error").

Please
