How do I retrieve data from statsd?

Question

I'm glossing over their documentation here :

http://www.rubydoc.info/github/github/statsd-ruby/Statsd

And there's methods for recording data, but I can't seem to find anything about retrieving recorded data. I'm adopting a projecting with an existing statsd addition. It's host is likely a defunct URL. Perhaps, is the host where those stats are recorded?

Answer 1

There are 2 parts to statsd: a client and a server.
What you're looking at is the client part. You will not see functionality related to retrieving the data as it's not there - it normally is on the server side.

Here is a list of statsd server implementations:

Statsd originally started at etsy: https://github.com/etsy/statsd/wiki

Answer 2

The statsd server implementations that Mircea links just take care of receiving, aggregating metrics and publishing them to a backend service. Etsy's statsd definition (bold is mine):

A network daemon that runs on the Node.js platform and listens for statistics, like counters and timers, sent over UDP or TCP and sends aggregates to one or more pluggable backend services (eg, Graphite) .

To retrieve the recorded data you have to query the backend. Check the list of available backends . The most common one is Graphite.
