Method Detail

explodeSummarizable

public static Map<String,Double> explodeSummarizable(com.yammer.metrics.core.Summarizable metric)

explodeSummarizable

public static Map<String,Double> explodeSummarizable(com.yammer.metrics.core.Summarizable metric,
                                                           boolean convertNanToZero)

Retrieve values for pre-defined stats (min/max/mean/sum/stddev) from a Summarizable metric (e.g. histogram)

Parameters:

metric - metric to retrieve stats from

convertNanToZero - simulate Histogram histogram behavior when used with WavefrontHistogram as input: when "true", empty WavefrontHistogram reports zero values for all stats

Returns:

summarizable stats

explodeSampling

public static Map<String,Double> explodeSampling(com.yammer.metrics.core.Sampling sampling)

explodeSampling

public static Map<String,Double> explodeSampling(com.yammer.metrics.core.Sampling sampling,
                                                       boolean convertNanToZero)

Retrieve values for pre-defined stats (median/p75/p95/p99/p999) from a Sampling metric (e.g. histogram)

Parameters:

sampling - metric to retrieve stats from

convertNanToZero - simulate Histogram histogram behavior when used with WavefrontHistogram as input: when "true", empty WavefrontHistogram reports zero values for all stats

Returns:

sampling stats
