MetricTypeQueryHandler

class MetricTypeQueryHandler extends Service[Request, Response]

A handler which accepts metrics metadata queries via http query strings and returns json encoded metrics with their types and an indicator of whether or not counters are latched.

This is a temporary endpoint which will be replaced by a more fleshed out metadata endpoint.

Note

When passing an explicit histogram metric via ?m=, users must provide the raw histogram name, no percentile (eg, .p99) appended. Example Request: http://$HOST:$PORT/admin/exp/metric_metadata?m=srv/http/requests&m=srv/http/pending&m=srv/mux/framer/write_stream_bytes Response: { "latched" : true, "metrics" : [ { "name" : "srv/http/requests", "kind" : "counter" }, { "name" : "srv/http/pending", "kind" : "gauge" }, { "name" : "srv/mux/framer/write_stream_bytes", "kind" : "histogram" } ] }
