The StatsD server written in Rust

Bioyino is a distributed statsd-protocol server with carbon backend.

• all basic metric types supported (gauge, counter, diff-counter, timer), new types are easy to be added
• fault tolerant: metrics are replicated to all nodes in the cluster
• clustering: all nodes gather and replicate metrics, but only leader sends metrics to backend
• precise: 64-bit floats, full metric set is stored in memory (for metric types that require post-processing), no approximation algorithms involved
• standalone: can work without external services
• safety and security: written in memory-safe language
• networking tries to do it's best to avoid dropping UDP packets as much as possible
• networking is asynchronous
• small memory footprint and low CPU consumption

Currently works in production at Avito, processing production-grade metric stream (~4M metrics per second on 3 nodes)

One of Bioyino's most powerful features - multimessage mode - require it to be working on GNU/Linux.

• Install capnp compiler tool to generate schemas. It's usually downloaded using your distribution's package manager.
• Do the usual Rust-program build-install cycle. Please note, that building is always tested on latest stable version of Rust. Rust 2018 edition is required.

$ git clone <this repo>

To configure, please, see config.toml, all the options are listed there and all of them are commented.

You can help project by doing the following:

• find TODOs/FIXMEs and unwraps in the code fix them and create a PR
• solve issues
• create issues to request new features
• add new features, like new metric types
• test the server on your environment and creating new issues if/when bugs found
