# logu

*logu* is for extracting patterns from (streaming) unstructured log messages.
For parsing unstructured logs, it uses the parser from
[Drain](https://github.com/logpai/Drain3).
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](https://github.com/grafana/loki/tree/v3.0.0/pkg/pattern/drain).
If you are interested in log parsers themselves,
other methods are summarized at
[logpai/logparser](https://github.com/logpai/logparser),
so please take a look.
## Features
