How It Works

The Hosted Graphite agent is an easy-to-use bundle of the popular metrics collector Diamond and the Supervisor process manager along with an embedded build of Python and some support scripts.

  

Features

  • Faster submission of metric data from your application because it doesn’t have to do a DNS lookup, or connect out across the internet.
  • More reliable delivery because the agent stores-and-forwards, buffering on disk when it can’t connect.
  • Easier debugging for the “my metric is missing” problem, because our UI can tell you that an agent has stopped responding.
  • More secure: the agent uses HTTPS and while we offer TLS-wrapped carbon protocols, it’s more effort to use than the plaintext ones. Sending straight to the agent bypasses this and we take care of it for you.
  • No need to prefix your metrics with an API key for HG’s authentication: it’s handled for you, using API key in the agent config.
  • No need to specify new firewall rules for carbon protocols and keep the rules updated - if you can already get HTTPS out of your network, even via a proxy, then it’ll work.

Roadmap

We’ll be adding lots more easy-to-configure collectors and dashboards.

If there’s something you’d like automated collection and dashboards for, let us know.
