Class StatsConfig

java.lang.Object

com.netflix.servo.stats.StatsConfig

public final class StatsConfig
extends java.lang.Object

Configuration options for a StatsTimer

By default we publish count (number of times the timer was executed), totalTime, and 95.0, and 99.0 percentiles.

The size for the buffer used to store samples is controlled using the sampleSize field, and the frequency at which stats are computed is controlled with the computeFrequencyMillis option. By default these are set to 100,000 entries in the buffer, and computation at 60,000 ms (1 minute) intervals.
