cystatsd

A c++/cython encoder for batches of statsd metrics.

The main class is cystatsd.MetricCollector, which accepts metrics and converts them into packets for batch submission to a StatsD server. Target packet size is configurable.

This doesn't make any network calls; it just does encoding.

This also doesn't currently do anything clever with stats, like collapsing submissions for the same counter. There's a potential for more optimization there.

Install

It requires Cython to build:

pip install cython

Then:

pip install cystatsd

Example

from cystatsd import MetricCollector
collector = MetricCollector()
collector.push_timer("some_timer", 200)
collector.push_counter("dogs", 2)
collector.push_counter("fish", 5, rate=0.1)
result = collector.flush()
print(result)

Outputs:

[b"some_timer:200|ms\ndogs:2|c\nfish:5|c|@0.10"]
