 @NotNull String header,
 @NotNull
 @org.jetbrains.annotations.NotNull double[] percentiles,
 Time time,
 @NotNull
 @NotNull TimeUnit latencyTimeUnit,
 io.micrometer.core.instrument.composite.CompositeMeterRegistry compositeRegistry)

Constructor PrintMetrics initializing all values.

Parameters:

header - NotNull String

percentiles - NotNull double[]

time - Time

latencyTimeUnit - NotNull TimeUnit

compositeRegistry - CompositeMeterRegistry

Method Details

close

public void close()

This method Closes this registry, releasing any resources in the process. Once closed, this registry will no longer accept new meters and any publishing activity will cease.
