Crate polkadot_node_subsystem_util::metrics::prometheus

Modules

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.

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.
register

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.
