This depends on https://github.com/prometheus/client_golang/pull/51. For vectors, the result format looks like this: ```json { "version": 1, "type" : "vector", "value" : [ { "timestamp" : 1421765411.045, "value" : "65.475000", "metric" : { "quantile" : "0.5", "instance" : "http://localhost:9090/metrics", "job" : "prometheus", "__name__" : "http_request_duration_microseconds", "handler" : "/static/", "method" : "get", "code" : "304" } }, { "timestamp" : 1421765411.045, "value" : "5826.339000", "metric" : { "quantile" : "0.9", "instance" : "http://localhost:9090/metrics", "job" : "prometheus", "__name__" : "http_request_duration_microseconds", "handler" : "prometheus", "method" : "get", "code" : "200" } }, /* ... */ ] } ``` For matrices, it looks like this: ```json { "version": 1, "type" : "matrix", "value" : [ { "metric" : { "quantile" : "0.99", "instance" : "http://localhost:9090/metrics", "job" : "prometheus", "__name__" : "http_request_duration_microseconds", "handler" : "/static/", "method" : "get", "code" : "200" }, "values" : [ [ 1421765547.659, "29162.953000" ], [ 1421765548.659, "29162.953000" ], [ 1421765549.659, "29162.953000" ], /* ... */ ] } ] } ```
