Grad: aggregate, store, query and visualize your metrics, all in one tool

Grad is meant to quickly and painlessly get metrics from your services and display them, by running only one service, instead of setting up an aggregator, a time series DB and a graph web application.

grad graphs, generated from sozu metrics

Warning: early stage software

This application is a proof of concept for now, already usable for debugging sessions, but still lacking in features and performance.

How it works

It gets statsd compatible (with InfluxDB tags support) metrics from UDP and stores them in memory.

Graphs are defined from a JSON file stored in the configuration directory, and accessible from this URL: http://localhost:3000/?dashboard=graph.json

Those configuration files follow this format:

{
  "title": "sozu",
  "graphs": [
    {
      "id": "requests",
      "title": "HTTP requests",
      "series": [
        "sozu.http.requests",
        "sozu.http.status.2xx",
        "sozu.http.status.3xx",
        "sozu.http.status.4xx",
        "sozu.http.status.5xx"
      ]
    },
    {
      "id": "protocols",
      "title": "Protocols",
      "series": [
        "sozu.protocol.http",
        "sozu.protocol.https",
        "sozu.protocol.tls_handshake"
      ]
    }
  ]
}

A page listing the available metrics is also exposed at http://localhost:3000/series
