Parsing RFC3164 logs for Grafana (lemmy.sdf.org)

submitted 1 year ago by [email protected] to c/[email protected]

Hey everyone ! I finally decided to monitor my applications more closely with Grafana. However I'm having issues building dashboards their logs.

Their logs are currently sent over syslog (in RFC3164 format) into telegraf. But it simply puts the whole message into the message field, so I can't use specific fields (eg. URL for httpd, source IP for DNS requests, username for SSH, …) to build graphs.

I've read about grok patterns, but I have no idea how to use them.

Would someone have any pointer on how I could make sense out of these logs for later use ?

It does help thank you ;)

I've found that you can use custom grok patterns to parse logs just as grayling extractors do. I'm still trying to figure it out, but so far I could start parsing logs using a [[processor.parser]] block. I'll document my findings when I get it working as I want it.
