logu is for extracting patterns from (streaming) unstructured log messages.
For parsing unstructured logs, it uses the parser from
Drain.
In simple terms, it tokenizes log messages,
builds a tree structure, and groups similar logs into a single cluster,
converting unstructured log data into a format that can be organized and analyzed.
This approach is also used by
Grafana Loki.
If you are interested in log parsers themselves,
other methods are summarized at
logpai/logparser,
so please take a look.
