Hello,

Could you please clarify how can I cut out some fields from forwarded event?

My situation is the following;

I have a local log file on the server where installed nxlog agent. Using im_file module I have defined path to file and filename. After that I configured to forward this log to remote syslog server. When I opened forwarded log on the romete syslog server and find out that my log line was changed. It was added time and server name wehere original log file is stored. I have posted a line from the remote server and marked columns which were added during the forwarding.

Can you help me?

Thank you in advance.

You are probably missing parse_syslog() but it is hard to tell without seing the actual config.

If the $Message field is not present - which is populated by parse_syslog() - then to_syslog_bsd() will use $raw_event. I assume this is why a new header is added.
