:undefined, :undefined, :undefined, :undefined}]

Create Metric Family of type, name and help. collector.collect_metrics/2 callback will be called and expected to return individual metrics list.

iex(13)> Prometheus.Model.gauge_metric(100, [host: "example.com"])
{:Metric, [{:LabelPair, "host", "example.com"}], {:Gauge, 100}, :undefined,
 :undefined, :undefined, :undefined, :undefined}

Creates gauge metrics from mdata {label, value} tuple list.

Creates histogram metric with buckets, count, sum, and labels.

iex(4)> Prometheus.Model.histogram_metric([{2, 1}, {5, 1}, {:infinity, 2}], 2, 10.5, [{:method, :get}])
{:Metric, [{:LabelPair, "method", "get"}], :undefined, :undefined, :undefined,
:undefined,
{:Histogram, 2, 10.5,
[{:Bucket, 1, 2}, {:Bucket, 1, 5}, {:Bucket, 2, :infinity}]}, :undefined}

Buckets is a list of pairs {upper_bound, cumulative_count}. Cumulative count is a sum of all cumulative_counts of previous buckets + counter of current bucket.

Creates histogram metrics from mdata {labels, buckets, count, sum} tuple list.

iex(2)> Prometheus.Model.histogram_metrics([{ [{:method, :get}], [{2, 1}, {5, 1}, {:infinity, 2}], 2, 10.5}])
[{:Metric, [{:LabelPair, "method", "get"}], :undefined, :undefined, :undefined,
  :undefined,
  {:Histogram, 2, 10.5,
   [{:Bucket, 1, 2}, {:Bucket, 1, 5}, {:Bucket, 2, :infinity}]}, :undefined}]

Creates summary metric with count, sum and labels.

iex(3)> Prometheus.Model.summary_metric(2, 10.5, [{:method, :get}])
{:Metric, [{:LabelPair, "method", "get"}], :undefined, :undefined,
  {:Summary, 2, 10.5, []}, :undefined, :undefined, :undefined}

Creates summary metrics from mdata {labels, count, sum} tuple list.

iex(7)> Prometheus.Model.summary_metrics([{[{:method, :get}], 2, 10.5}])
[{:Metric, [{:LabelPair, "method", "get"}], :undefined, :undefined,
  {:Summary, 2, 10.5, []}, :undefined, :undefined, :undefined}]

Creates untyped metric with value and labels

iex(13)> Prometheus.Model.untyped_metric(100, [host: "example.com"])
{:Metric, [{:LabelPair, "host", "example.com"}], :undefined,
 :undefined, :undefined, {:Untyped, 100}, :undefined, :undefined}

Creates untyped metrics from mdata {label, value} tuple list.

iex(11)> Prometheus.Model.untyped_metrics([{[host: "example.com"], 100}])
[{:Metric, [{:LabelPair, "host", "example.com"}], :undefined,
:undefined, :undefined, {:Untyped, 100}, :undefined, :undefined}]
