Reset deletes all metrics in this vector.

WithUnit sets the unit for a Desc.

Collect is called by the Prometheus registry when collecting metrics. The implementation sends each collected metric via the provided channel and retu

Query performs a query for the given time.

Register registers a new Collector to be included in metrics collection. It returns an error if the descriptors provided by the Collector are invalid

Gather implements Gatherer.

MustNewConstMetric is a version of NewConstMetric that panics where NewConstMetric would have returned an error.

Wait sleeps for the backoff time then increases the retry count and backoff time. Returns immediately if Context is terminated.

WithLabelValues works as GetMetricWithLabelValues, but panics where GetMetricWithLabelValues would have returned an error. Not returning an error allo

Desc returns the descriptor for the Metric. This method idempotently returns the same descriptor throughout the lifetime of the Metric. The returned d

NewGaugeVec creates a new GaugeVec based on the provided GaugeOpts and partitioned by the given label names.

BuildFQName joins the given three name components by "_". Empty name components are ignored. If the name parameter itself is empty, an empty string is

NewGoCollector returns a collector that exports metrics about the current Go process using debug.GCStats (base metrics) and runtime/metrics (both in M

toNormalizedJSON removes fake random space from proto JSON original marshaller. It is required, so we can compare proto messages in json format. Read

MakeLabelPairs is a helper function to create protobuf LabelPairs from the variable and constant labels in the provided Desc. The values for the varia

Problem with the sliding-window decay algorithm... The Merge method of perk/quantile is actually not working as advertised - and it might be unfixable

SizeOfVarint returns the size of the varint-encoded value.

NewClient returns a new Client. It is safe to use the returned Client from multiple goroutines.

Observe adds a single observation to the histogram. Observations are usually positive or zero. Negative observations are accepted but prevent current

NewSummaryVec creates a new SummaryVec based on the provided SummaryOpts and partitioned by the given label names. Due to the way a Summary is repres

Describe sends the super-set of all possible descriptors of metrics collected by this Collector to the provided channel and returns once the last desc

EncodeVarint encodes a uint64 into a varint-encoded byte slice and returns the offset of the encoded value. The provided offset is the offset after th

HandlerForTransactional is like HandlerFor, but it uses transactional gather, which can safely change in-place returned *dto.MetricFamily before call

InstrumentHandlerCounter is a middleware that wraps the provided http.Handler to observe the request result with the provided CounterVec. The CounterV

InstrumentHandlerDuration is a middleware that wraps the provided http.Handler to observe the request duration with the provided ObserverVec. The Obse

MustRegister registers the provided Collectors with the DefaultRegisterer and panics if any error occurs. MustRegister is a shortcut for DefaultRegis

NewAPI returns a new API for the client. It is safe to use the returned API from multiple goroutines.

NewGoCollector is the obsolete version of collectors.NewGoCollector. See there for documentation. Deprecated: Use collectors.NewGoCollector instead.

checkLabels returns whether the provided Collector has a non-const, non-curried label named "code" and/or "method". It panics if the provided Collecto

init provides the selfCollector with a reference to the metric it is supposed to collect. It is usually called within the factory function to create a

NewTimer creates a new Timer. The provided Observer is used to observe a duration in seconds. If the Observer implements ExemplarObserver, passing exe

Register implements Registerer.

WithLabelValues works as GetMetricWithLabelValues, but panics where GetMetricWithLabelValues would have returned an error. Not returning an error allo

WrapRegistererWith returns a Registerer wrapping the provided Registerer. Collectors registered with the returned Registerer will be registered with t

DeleteLabelValues removes the metric where the variable labels are the same as those passed in as labels (same order as the VariableLabels in Desc). I

Header sets a custom HTTP header for the Pusher's client. For convenience, this method returns a pointer to the Pusher itself.
