MetricMetadataQueryHandler

class MetricMetadataQueryHandler extends Service[Request, Response]

A handler which accepts metrics metadata queries via http query strings and returns json encoded metrics with the metadata contained in their MetricSchemas, as well as an indicator of whether or not counters are latched.

Note

When passing an explicit histogram metric via ?name=, users must provide the raw histogram name, no percentile (eg, .p99) appended. Example Request: http://$HOST:$PORT/admin/metric_metadata?name=my/cool/counter&name=your/fine/gauge&name=my/only/histo Response: { "@version" : 2.0, "counters_latched" : false, "metrics" : [ { "name" : "my/cool/counter", "relative_name" : ["cool","counter"], "kind" : "counter", "source" : { "class": "finagle.stats.cool", "category": "Server", "process_path": "dc/role/zone/service" }, "description" : "Counts how many cools are seen", "unit" : "Requests", "verbosity": "Verbosity(default)", "key_indicator" : true }, { "name" : "your/fine/gauge", "relative_name" : ["fine","gauge"], "kind" : "gauge", "source" : { "class": "finagle.stats.your", "category": "Client", "process_path": "dc/your_role/zone/your_service" }, "description" : "Measures how fine the downstream system is", "unit" : "Percentage", "verbosity": "Verbosity(debug)", "key_indicator" : false }, { "name" : "my/only/histo", "relative_name" : ["histo"], "kind" : "histogram", "source" : { "class": "Unspecified", "category": "NoRoleSpecified", "process_path": "Unspecified" }, "description" : "No description provided", "unit" : "Unspecified", "verbosity": "Verbosity(default)", "key_indicator" : false, "buckets" : [ 0.5, 0.9, 0.99, 0.999, 0.9999 ] } ]}
