Detailed Description

Interface for prometheus (https://prometheus.io/)

Constructor & Destructor Documentation

◆ 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

Member Function Documentation

◆ boolMetric()

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

pure virtual

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

Implemented in util::prometheus::PrometheusImpl.

◆ collectMetrics()

virtual std::string util::prometheus::PrometheusInterface::collectMetrics ( )

pure virtual

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

Returns: The serialized metrics

Implemented in util::prometheus::PrometheusImpl.

◆ compressReplyEnabled()

bool util::prometheus::PrometheusInterface::compressReplyEnabled ( ) const

inline

Whether to compress the reply.

Returns: true if the reply should be compressed

◆ counterDouble()

virtual CounterDouble & util::prometheus::PrometheusInterface::counterDouble	(	std::string	name,
		Labels	labels,
		std::optional< std::string >	description = std::nullopt )

pure virtual

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

Implemented in util::prometheus::PrometheusImpl.

◆ counterInt()

virtual CounterInt & util::prometheus::PrometheusInterface::counterInt	(	std::string	name,
		Labels	labels,
		std::optional< std::string >	description = std::nullopt )

pure virtual

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

Implemented in util::prometheus::PrometheusImpl.

◆ gaugeDouble()

virtual GaugeDouble & util::prometheus::PrometheusInterface::gaugeDouble	(	std::string	name,
		Labels	labels,
		std::optional< std::string >	description = std::nullopt )

pure virtual

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

Implemented in util::prometheus::PrometheusImpl.

◆ gaugeInt()

virtual GaugeInt & util::prometheus::PrometheusInterface::gaugeInt	(	std::string	name,
		Labels	labels,
		std::optional< std::string >	description = std::nullopt )

pure virtual

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

Implemented in util::prometheus::PrometheusImpl.

◆ histogramDouble()

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

pure virtual

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

Implemented in util::prometheus::PrometheusImpl.

◆ histogramInt()

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

pure virtual

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

Implemented in util::prometheus::PrometheusImpl.

◆ isEnabled()

bool util::prometheus::PrometheusInterface::isEnabled ( ) const

inline

Whether prometheus is enabled.

Returns: true if prometheus is enabled
