Hi, I was wondering what would happen when the log received hostname matches the bad-hostname and check-hostname options. Its not written in the documentation clearly. My use case was, i have syslog running on my server that is receiving logs from multiple servers. I have all of them into a central folder. A pesudo config I am using would be: source s_udp { network(ip("1.1.1.1") transport("udp") port(514)); }; destination d_servers { file("/mnt/logs/$HOST/$YEAR-$MONTH-$DAY.log"); }; log { source(s_udp); destination(d_servers); }; However, with this config i received weird stuff in the /mnt/logs folder. [image: image.png] I was thinking if using both check-hostname and bad-hostname would help reduce such stuffs.

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
