Class DropwizardMetricWriter

java.lang.Object

org.springframework.boot.actuate.metrics.writer.DropwizardMetricWriter

All Implemented Interfaces:

CounterWriter, GaugeWriter, MetricWriter

Deprecated.

Since 1.3 in favor of DropwizardMetricServices

@Deprecated
public class DropwizardMetricWriter
extends Object
implements MetricWriter

A MetricWriter that send data to a Dropwizard MetricRegistry based on a naming convention.

• Updates to increment(Delta) with names in "meter.*" are treated as Meter events
• Other deltas are treated as simple Counter values
• Inputs to set(Metric) with names in "histogram.*" are treated as Histogram updates
• Inputs to set(Metric) with names in "timer.*" are treated as Timer updates
• Other metrics are treated as simple Gauge values (single valued measurements of type double)

Create a new DropwizardMetricWriter instance.

Parameters:

registry - the underlying metric registry

Method Detail

increment

public void increment(Delta<?> delta)

Deprecated.

Description copied from interface: CounterWriter

Increment the value of a metric (or decrement if the delta is negative). The name of the delta is the name of the metric to increment.

Specified by:

increment in interface CounterWriter

Parameters:

delta - the amount to increment by

set

public void set(Metric<?> value)

Deprecated.

Description copied from interface: GaugeWriter

Set the value of a metric.

Specified by:

set in interface GaugeWriter

Parameters:

value - the value

reset

public void reset(String metricName)

Deprecated.

Description copied from interface: CounterWriter

Reset the value of a metric, usually to zero value. Implementations can discard the old values if desired, but may choose not to. This operation is optional (some implementations may not be able to fulfill the contract, in which case they should simply do nothing).

Specified by:

reset in interface CounterWriter

Parameters:

metricName - the name to reset
