Parsing IRC Logs

Elastic Stack Logstash
1

Im running an ELK-Stack in Docker and my goal is, to parse and filter my IRC logs, for learning.

2024-04-01 20:25:02     me foo
2024-04-01 20:25:46     me bar

I found some logstash related stuff on Github. I guess the input and output part is similar, but I don't understand the filter related part. Do you have maybe some suggestions? I mean it's some years old.

thx

You can check the configuration examples from the documentation to understand how logstash works.

And then the filters documentation to see which filters are available.

How you will parse depends on what you want to do with the data and how the message looks like.

Few more tips:

  • Do you grok Grok? | Elastic Blog
  • IRC grok pattern is simple: timestamp, username, message. Can be something like this: %{TIMESTAMP_ISO8601:timestamp}\s+%{NOTSPACE:username}\s+%{GREEDYDATA:ircmessage}
  • in your case csv and dissect are also suitable for use
