Crate aptos_metrics_core

Modules

op_counters

OpCounters is a collection of convenience methods to add arbitrary counters to modules. For now, it supports Int-Counters, Int-Gauges, and Histogram.

Macros

monitor

Helper function to record metrics for external calls. Include call counts, time, and whether it’s inside or not (1 or 0). It assumes a OpMetrics defined as OP_COUNTERS in crate::counters;

register_histogram

Create a Histogram and registers to default registry.

register_histogram_vec

Create a HistogramVec and registers to default registry.

register_int_counter

Create an IntCounter and registers to default registry.

register_int_counter_vec

Create an IntCounterVec and registers to default registry.

register_int_gauge

Create an IntGauge and registers to default registry.

register_int_gauge_vec

Create an IntGaugeVec and registers to default registry.

Structs

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.

HistogramTimer

Timer to measure and record the duration of an event.

TextEncoder

An implementation of an Encoder that converts a MetricFamily proto message into text format.

Traits

Encoder

An interface for encoding metric families into an underlying wire protocol.

Functions

gather

Return all MetricFamily of DEFAULT_REGISTRY.

Type Definitions

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).

IntGauge

The integer version of Gauge. Provides better performance if metric values are all integers.

IntGaugeVec

The integer version of GaugeVec. Provides better performance if metric values are all integers.
