      Description

      It’s possible for a Windows server to forward its events to a “subscribing” server. In this scenario the collector server can become a central repository for Windows logs from other servers in the network. Zabbix agent can be installed on the collector and can be used to monitor received logs from other servers.

      The issue is that Zabbix agent does not send events from the "Forwarded Events" event log from collector. It does not generate any errors also.

      Details:

      • Zabbix agent has 2 items:
        eventlog[ForwardedEvents,,,,4625,,]
        eventlog[Security,,,,4625,,]
      • It sends events from the Security log, but does not send for ForwardedEvents
      • It does not generate an error for ForwardedEvents also
      • Tried to change user from System to administrator - didn't help

      Debug has no clue about the root cause:

      Note, log size is ~30MB (not "lastlogsize:0"). Agent can see that the log has new events but does not send them (e.g. LastID: 12572 --> LastID: 12584).
