Macros

histogram_opts

Create a HistogramOpts.

Structs

Counter

The underlying implementation for Counter and IntCounter.

F64

A atomic float.

Gauge

The underlying implementation for Gauge and IntGauge.

Histogram

A Metric counts individual observations from an event or sample stream in configurable buckets. Similar to a Summary, it also provides a sum of observations and an observation count.

HistogramOpts

A struct that bundles the options for creating a Histogram metric. It is mandatory to set Name and Help to a non-empty string. All other fields are optional and can safely be left at their zero value.

I64

A atomic signed integer.

Opts

A struct that bundles the options for creating most Metric types.

Registry

A struct for registering Prometheus collectors, collecting their metrics, and gathering them into MetricFamilies for exposition.

SourcedMetric

A metric whose values are obtained from an existing source, instead of being independently recorded.

U64

A atomic unsigned integer.

Enums

Error

PrometheusError

The error types for prometheus.

Traits

MetricSource

A source of values for a SourcedMetric.

Functions

exponential_buckets

Create count buckets, where the lowest bucket has an upper bound of start and each following bucket’s upper bound is factor times the previous bucket’s upper bound. The final +Inf bucket is not counted and not included in the returned slice. The returned slice is meant to be used for the Buckets field of HistogramOpts.

init_prometheus

Initializes the metrics context, and starts an HTTP server to serve metrics.

linear_buckets

Create count buckets, each width wide, where the lowest bucket has an upper bound of start. The final +Inf bucket is not counted and not included in the returned slice. The returned slice is meant to be used for the Buckets field of HistogramOpts.

Type Aliases

CounterVec

The underlying implementation for CounterVec and IntCounterVec.

GaugeVec

The underlying implementation for GaugeVec and IntGaugeVec.

HistogramVec

A Collector that bundles a set of Histograms that all share the same Desc, but have different values for their variable labels. This is used if you want to count the same thing partitioned by various dimensions (e.g. HTTP request latencies, partitioned by status code and method).

SourcedCounter

A counter whose values are obtained from an existing source.

SourcedGauge

A gauge whose values are obtained from an existing source.
