Crate fedimint_metrics

Re-exports§

histogram_opts: Create a HistogramOpts.
opts: Create an Opts.
register_histogram_with_registry: Create a Histogram and registers to a custom registry.
register_int_counter_vec_with_registry: Create an IntCounterVec and registers to a custom registry.

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.
HistogramTimerExt: A wasm-safe histogram timer that uses fedimint_core::time::now instead of std::time::Instant, which is not available on wasm targets.
TextEncoder: An implementation of an Encoder that converts a MetricFamily proto message into text format.

Encoder: An interface for encoding metric families into an underlying wire protocol.
HistogramExt: Extension trait for Histogram that provides a wasm-safe timer.

get_metrics: Returns all registered metrics encoded in Prometheus text format.
spawn_api_server: Spawns an HTTP server that exposes Prometheus metrics on /metrics.

Gauge: A Metric represents a single numerical value that can arbitrarily go up and down.
GaugeVec: A Collector that bundles a set of Gauges 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. number of operations queued, partitioned by user and operation type).
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).
IntCounter: The integer version of Counter. Provides better performance if metric values are all positive integers (natural numbers).
IntCounterVec: The integer version of CounterVec. Provides better performance if metric are all positive integers (natural numbers).
