package org.apache.kafka.common.metrics
Provides the API used by Kafka clients to emit metrics which are then exposed using the * MetricsReporter interface.
  • Class
    Description
    CompoundStat
    A compound stat is a stat where a single measurement and associated data structure feeds many metrics.
    CompoundStat.NamedMeasurable
     
    Gauge<T>
    A gauge metric is an instantaneous reading of a particular value.
    JmxReporter
    Register metrics in JMX as dynamic mbeans based on the metric names
    KafkaMetric
     
    KafkaMetricsContext
    A implementation of MetricsContext, it encapsulates required metrics context properties for Kafka services and clients
    Measurable
    A measurable quantity that can be registered as a metric
    MeasurableStat
    A MeasurableStat is a Stat that is also Measurable (i.e. can produce a single floating point value).
    MetricConfig
    Configuration values for metrics
    Metrics
    A registry of sensors and metrics.
    MetricsContext
    MetricsContext encapsulates additional contextLabels about metrics exposed via a MetricsReporter
    MetricsReporter
    A plugin interface to allow things to listen as new metrics are created so they can be reported.
    MetricValueProvider<T>
    Super-interface for Measurable or Gauge that provides metric values.
    Quota
    An upper or lower bound for metrics
    QuotaViolationException
    Thrown when a sensor records a value that causes a metric to go outside the bounds configured as its quota
    Sensor
    A sensor applies a continuous sequence of numerical values to a set of associated metrics.
    Sensor.RecordingLevel
     
    Stat
    A Stat is a quantity such as average, max, etc that is computed off the stream of updates to a sensor
