    Windows Event Log Trigger Threshold

    Good morning.

    Looking into the viability of Windows event log filtering for the Zabbix Appliance 2.2. Currently we are monitoring a few windows hosts via event logs and the triggers are working great out of the box.

    Standard Event Log Trigger
    {Windows Logging:eventlog[System].logseverity(0)}=4

    Looking to try and create a trigger which will not fire unless there is three(3) repeated instances of the same error occur within 5 mins.

    Here is the content we're searching for from the eventlog.
    Authentication Failed for user 'BLUSSENHEIDE'

    Would it be something along these lines for timing? How could I quantify the repeat count?

    (({Windows Logging:eventlog[System].logseverity(0)})=4) & (({Windows Logging:eventlog[System].regexp("Authentication Failed for user")})=1) & ({Windows Logging:eventlog[System].nodata(300)}=1)

    Any assistance would be most appreciated.
    Thank You,
    BLussenheide
