Package bucket provides utility functions for constructing and merging histogram buckets.

Package push integrates go.uber.org/net/metrics with push-based telemetry systems like Graphite and M3.

Package tallypush integrates go.uber.org/net/metrics with push-based StatsD and M3 systems.

IsValidName checks whether the supplied string is a valid metric and tag name in both Prometheus and Tally.

IsValidTagValue checks whether the supplied string is a valid tag value in both Prometheus and Tally.

New constructs a root.

Placeholders for empty tag names and values.

Placeholders for empty tag names and values.

Version is the current semantic version, exported for runtime compatibility checks.

A Counter is a monotonically increasing value, like a car's odometer.

A CounterVector is a collection of Counters that share a name and some constant tags, but also have a consistent set of variable tags.

A Gauge is a point-in-time measurement, like a car's speedometer.

A GaugeVector is a collection of Gauges that share a name and some constant tags, but also have a consistent set of variable tags.

A Histogram approximates a distribution of values.

A HistogramSnapshot is a point-in-time view of the state of a Histogram.

A HistogramSpec configures Histograms and HistogramVectors.

A HistogramVector is a collection of Histograms that share a name and some constant tags, but also have a consistent set of variable tags.

A Root is a collection of tagged metrics that can be exposed via in-memory snapshots, push-based telemetry systems, or a Prometheus-compatible HTTP handler.

A RootSnapshot exposes all the metrics contained in a Root and all its Scopes.

A Scope is a collection of tagged metrics.

A Snapshot is a point-in-time view of the state of any non-histogram metric.

A Spec configures Counters, Gauges, CounterVectors, and GaugeVectors.

An Option configures a root.

Tags describe the dimensions of a metric.
