Flowgger is a fast, simple and lightweight data collector written in Rust.

It reads log entries over a given protocol, extracts them, decodes them using a given format, re-encodes them into a different format, and asynchronously pushes the result into a remote data store.

Flowgger is designed to be:

• Paranoid: it carefully validates input data to prevent injection of malformed/incomplete records down the chain.
• Safe: written in Rust, without any unsafe code.
• Fast: even though messages are systematically parsed and validated, Flowgger is orders of magnitude faster than Logstash and Fluentd.
• Standalone: it comes as a single executable file, and doesn't require a JVM.

Flowgger supports common input types: stdin, UDP, TCP, TLS and Redis.
