Metric-Apdex

metrics-apdex is an extension to Dropwizards's metrics library which enhances the existing Gauge metric type and provide it with the capability to calculate Apdex score by converting the measurements into insights about user satisfaction.

Installation

Add this to your build.gradle's dependencies:

implementation 'com.github.jainsahab:metric-apdex:1.0.0'

Usage

Configure a ApdexGauge with a threshold value.

     ApdexGauge apdexGauge = new ApdexGauge(0.03);  // 30 milliseconds

Add the recorded measurements.

    long[] values = {13, 21, 29, 17, 19, 23, 79, 49, 61, 139};
    for (long value : values) {
      apdexGauge.add(value);
    }

Retrieve the Apdex score.

    apdexGauge.getValue(); // 0.75
