Global Percentiles

Datadog launched a beta for Global Percentiles, making it possible to compute accurate DogstatsD percentiles across hosts.

With the beta activated histograms percentiles are calculated server-side (by sending sketches of the histogram data per host to the server), instead of at the host.

Please drop an email to to have the beta activated!

By using the beta, Datadog provides the min, count, sum, avg, p50, p75, p90, p95, p99, max for each unique tag combination for a given metric name.

Note that host-level tags will be stripped by default to reduce cardinality, but users will have the ability to optionally add back host-level tags as needed. Custom tags will be defined the same way as DogStatsD Histograms today.
