NXlog agent not collecting the windows security event from Forwarded Events.


#1 jilin

Hi

We are not receiving the Windows security logs via the nxlog agent. We noticed that nxlog.log successfully connected the destination IP, and port.

Hi jilin,

Your pm_transformer block does not seem to be used in your config, could you please try bypassing it to see if there is any improvement? Please change your Route Path 

from:
 Path eventlog => eventlog_transformer => syslogout  

to:
Path eventlog => syslogout

Cheers,
Konstantinos
