Statsd MMV agent for Performance Co-Pilot

Aggregates statsd packets recieved via UDP or TCP and sends them into PCP via MMV API. Mapping is currently 1:1 into PCP namespace, there is no possibility to map statsd metrics to instances. The following statsd types are supported:

  • example.counter => example.counter
  • example.gauge => example.gauge
  • example.duration => example.duration[mean,min,max,variance,standard_deviation]

Duration metric is aggregated using HDRHistogram with buckets set from 0 to 24 hours with 3 significant digits (currently hardcoded) and mean, minimum, maximum, variance and standard deviation is calculated for each PCP update.

Usage

Install PCP, enable MMV PMDA and run this daemon. Metrics will appear under mmv.* namespace.

$ pcp-mmvstatsd -h
