event log windows

[roulitto]

Hi,

Noob on zabbix I need to supervise event log system windows as ITEMS.

Zabbix version : 1.8

Configuration of the trigger :
HOST : servername
DESCRIPTION : Windows Event Logs - System
TYPE : ZABBIX AGENT (active)
KEY : eventlog[system]
TYPE OF INFORMATION : log
UPDATE INTERVAL : 30
NEW FLEXIBLE INTERVAL : 1-7,00:00-23:59
KEEP HISTORY : 90
STATUS : active
LOG TIME FORMAT :
NEW APPLICATION :
APPLICATION : none

It return as response in lastest data :
LAST VALUE : 0.000000
CHANGE : -

Any idea why it doesn't work?

Is anyone can make a tuto with print screen?
Is riggers an obligation?

thanks
