Implementation of PrometheusInterface.

Note: When prometheus is disabled, all metrics will still counted but collection is disabled

Member Function Documentation

◆ boolMetric()

Bool util::prometheus::PrometheusImpl::boolMetric	(	std::string	name,
		Labels	labels,
		std::optional< std::string >	description = std::nullopt )

overridevirtual

Get a bool based metric. It will be created if it doesn't exist.

Note: Prometheus does not have a native bool type, so we use a counter with a value of 0 or 1

Parameters

name	The name of the metric
labels	The labels of the metric
description	The description of the metric

Returns: The bool object

Implements util::prometheus::PrometheusInterface.

◆ collectMetrics()

std::string util::prometheus::PrometheusImpl::collectMetrics ( )

overridevirtual

Collect all metrics and return them as a string in Prometheus format.

Returns: The serialized metrics

Implements util::prometheus::PrometheusInterface.

◆ counterDouble()

CounterDouble & util::prometheus::PrometheusImpl::counterDouble	(	std::string	name,
		Labels	labels,
		std::optional< std::string >	description )

overridevirtual

Get a double based counter metric. It will be created if it doesn't exist.

Parameters

name	The name of the metric
labels	The labels of the metric
description	The description of the metric

Returns: A reference to the counter object

Implements util::prometheus::PrometheusInterface.

◆ counterInt()

CounterInt & util::prometheus::PrometheusImpl::counterInt	(	std::string	name,
		Labels	labels,
		std::optional< std::string >	description )

overridevirtual

Get an integer based counter metric. It will be created if it doesn't exist.

Parameters

name	The name of the metric
labels	The labels of the metric
description	The description of the metric

Returns: A reference to the counter object

Implements util::prometheus::PrometheusInterface.

◆ gaugeDouble()

GaugeDouble & util::prometheus::PrometheusImpl::gaugeDouble	(	std::string	name,
		Labels	labels,
		std::optional< std::string >	description )

overridevirtual

Get a double based gauge metric. It will be created if it doesn't exist.

Parameters

name	The name of the metric
labels	The labels of the metric
description	The description of the metric

Returns: A reference to the gauge object

Implements util::prometheus::PrometheusInterface.

◆ gaugeInt()

GaugeInt & util::prometheus::PrometheusImpl::gaugeInt	(	std::string	name,
		Labels	labels,
		std::optional< std::string >	description )

overridevirtual

Get an integer based gauge metric. It will be created if it doesn't exist.

Parameters

name	The name of the metric
labels	The labels of the metric
description	The description of the metric

Returns: A reference to the gauge object

Implements util::prometheus::PrometheusInterface.

◆ histogramDouble()

HistogramDouble & util::prometheus::PrometheusImpl::histogramDouble	(	std::string	name,
		Labels	labels,
		std::vector< double > const &	buckets,
		std::optional< std::string >	description = std::nullopt )

overridevirtual

Get a double based histogram metric. It will be created if it doesn't exist.

Parameters

name	The name of the metric
labels	The labels of the metric
buckets	The buckets of the metric
description	The description of the metric

Returns: A reference to the histogram object

Implements util::prometheus::PrometheusInterface.

◆ histogramInt()

HistogramInt & util::prometheus::PrometheusImpl::histogramInt	(	std::string	name,
		Labels	labels,
		std::vector< std::int64_t > const &	buckets,
		std::optional< std::string >	description = std::nullopt )

overridevirtual

Get an integer based histogram metric. It will be created if it doesn't exist.

Parameters

name	The name of the metric
labels	The labels of the metric
buckets	The buckets of the metric
description	The description of the metric

Returns: A reference to the histogram object

Implements util::prometheus::PrometheusInterface.

◆ PrometheusInterface()

util::prometheus::PrometheusInterface::PrometheusInterface	(	bool	isEnabled,
		bool	compressReply )

inline

Construct a new Prometheus Interface object.

Parameters

isEnabled	Whether prometheus is enabled
compressReply	Whether to compress the reply
