The artifacts are published to Bintray. If you're using gradle, use the
jcenter() repository and put this in your
Or, if you're on Maven, see the Set Me Up button at https://bintray.com/bintray/jcenter and then add the dependency.
Then, use the following reservoir implementations when you create your
HdrHistogramReservoir, a reservoir that accumulates its internal state forever
HdrHistogramResetOnSnapshotReservoir, a reservoir that resets its internal state on each snapshot (which is how reporters get information from reservoirs). See this article for when that is useful.
See http://hdrhistogram.org/ for why you want HdrHistogram as the underlying data structure, or watch Gil Tene talking about how latency is hard to measure well, or read this thread. The short version:
- It's very fast (tens of nanoseconds to record)
- It won't lose the outliers, which are the measurements you care about since latency is most assuredly not normally distributed
- It doesn't allocate (except for the occasional resize, or you can pre-size your histograms to not allocate at all)
Also, check out some simple benchmarks of the various reservoir implementations.
