Windows Api Sensor - Filter not working

Votes:

0

I want to set up a filter with the Windows-Api Eventlog-Sensor. I set it up in protocol for Windows Security Protocol and in type for Security Audit Errors.

Without filtering I get new entries in the monitoring tool, when a failure happens.

When I apply any filter, e.g. eventId or just a string in the message filter (and these strings actually are there in the event protocol messages) I get no event logged by the prtg monitor.

Sometimes when I reset the filter also without filter nothing is logged anymore by prtg. I have to apply a new sensor with the same configuration and this one works (just without any filter).

Dear Mr. Schubert,

as recommended in the support ticket, please check at first if the WMI version of this sensor works. Thank you!
