Graphite

What's "scalable" in graphite?

Asked by Jens Rantil

Hey,

On the frontpage of http://graphite.wikidot.com you write that Graphite is "scalable". What do you mean by that? I'm trying to wrap my head around whether you would allow me to shard counters across multiple machines or whatever, but can't find any evidence of this.

Looking forward to you answer,
Jens

Graphite is scalable in that it supports multiple instances behind the carbon relay. We use this for high availability and load balancing in our environment. Thus each metric gets sent to 2 of our 4 graphite servers. This also helps with our front end load as the webapp sits behind a load balancer. If you want to spin up more graphite servers, just add them to carbon.conf and the relay will start sending them metrics.

One caveat - you cannot (currently) shard a single counter across multiple
servers (with whisper). You can put counter A, B, C on Server1, and D, E,
F on Server2, then draw A-F on one graph.

Hope this helps.
