If those options match in the hostname field, syslog-ng will assume it didn't get a hostname, and shifts that value to the start of the message field, so they will be parsed into PROGRAM.

alternatively you can use the no-parse flag, fix the value and apply a syslog-parser() later.

Hi,

Anybody used the syslog-ng options bad_hostname & check_hostname?

How does that works?

I have syslog-ng listening on UDP, and found that there are some gibberish logs in the folder. Was thinking if using the above two options would help reduce the gibberish.

Yours Sincerely,
Delon
