Method Detail

build

@Nonnull
public DropwizardMetricStrategy build()

maxNumberOfMetrics

@Nonnull
public DropwizardMetricStrategy.Builder maxNumberOfMetrics(int value)

Sets the maximum number of metrics allowed in the underlying Codahale registry. The strategy will not add new metrics to the registry when the registry contains the maximum number of allowed metrics, or more. This can be used to limit the amount of memory used for metrics. Using the default settings, expect about 250kb of memory usage per timer. The default value is 128 (which translates to about 32MB of memory).

Parameters:

value - the maximum number of metrics that can be created by the strategy

Returns:

the builder

reservoirSize

@Nonnull
public DropwizardMetricStrategy.Builder reservoirSize(int value)

Sets the reservoir size used for calculating statistics for timers and histograms. Default value is 2048.

Parameters:

value - the reservoir size to use

Returns:

the builder
