Help for Event logs for version 1.8.3

[JoeCheuk]

I need to monitor our server for event log. I have no problem to check the event log content from Zabbix server.

({Template_WINSERVER_EVENTS:eventlog[System,,"Warning"].str(Test from joe)}=1)

However, I want to Zabbix Server to send alert (email) when it receive more than 3 with 60 sec. Any help???

Many thanks!
