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
    An 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.
    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.
    Monitorable
    Plugins can implement this interface to register their own metrics.
    PluginMetrics
    This allows plugins to register metrics and sensors.
    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
