    Observe failed Logon Events on DC

    Hi everyone,


    my goal is to have a trigger that fires when more than 3 failed logon events have occurred within 30 minutes and the problem shouldn't disappear by itself.

    I've already spent a lot of time on this issue and can't get any further.
    I also came across a post here in the forum where the solution unfortunately didn't work for me.

    My item is included:
    eventlog[Security,,,,4625,,skip]

    Together with this item, I tried the following triggers, which did not work:
    last(/APP-Domain Controller by Zabbix Agent 2 active/eventlog.count[Security,,,,4625,,skip])>=3

    count(/APP-Domain Controller by Zabbix Agent 2 active/eventlog[Security,,,,4625,,skip],30m, "eq",4625)>=3



    I have also experimented with the item key eventlog.count, but unfortunately a trigger there cancels itself if the value is below 3 in the following 30 minutes.

    I would be very grateful for your help
