Crate graphite

graphite-rust

Herein lies a humble reimplementation of the graphite metrics system. It's a time series database system, with frontend and management tools, that strikes a reasonable balance between features, ease of management, and a nice network of tools which can talk to graphite.

graphite-rust aims to maintain total compatibility with features and file format of your normal graphite installation. Just made easier by one binary. And possibly higher performance but that's not the main goal right now. Although I am pursing a batch-write model out the gate -- but that's mostly to understand how to work with vectors.

This work falls under the name graphite but in reality the package has distinct components you may want to understand:

• whisper - all the heavy lifting for parsing and writing to whisper database files
• carbon - the network daemon which mediates access to whisper files
• graphite - the HTTP REST server which handles queries. It has a minimal HTML application for creating dashboard but I'll be skipping that. For dashboard you'll want grafana.

Status of the codes:

• whisper
  • DOES open and parse header/metadata/archive info
  • IN PROGRESS take a metric value and provide a WriteOp
  • NOT STARTED write vec![WriteOp] to file
• carbon
  • DOESN'T DO ANYTHING
• graphite
  • DOESN'T EXIST

Also, this is brand-new code. In the true rust spirit it does not guarantee the safety of your kittens.

Modules

whisper

All the code necessary for creating, reading, and updating whisper database files. The 'standard' for whisper files is defined primarily from the source code. It's a straight-forward format for static allocation of time-series
