Abstract MBean interface for objects that describe the general characteristics of a distribution of (double) values recorded as a histogram. This interface supports the standard MBean management interface, so implementing classes will support JMX monitoring.

public interface HistogramMBean extends DistributionMBean {

    
Gets the total number of buckets. Note that this includes any buckets added to handle out-of-range values.
    int getNumBuckets();

    
Gets the number of values recorded in each bucket.
    long[] getBucketCounts();

    
Gets the minimum bound for the histogram buckets. This is an inclusive minimum; values equal to the bucket limit are counted in this bucket.
    double[] getBucketMinimums();

    
Gets the maximum bound for the histogram buckets. This is an exclusive maximum; values equal to the bucket limit are counted in the subsequent bucket.
    double[] getBucketMaximums();

    
Gets the approximate median value, that is the value where half of the observed values are less than the median and half are greater.
    double getMedian();

    
Gets the (approximate) percentile value, that is the value where some desired percent of the observed values are less than the percentile value and the remainder are greater.
    double getPercentile(int percent);

    
Gets the (approximate) percentage of observed values that are less than a given value.
    long getPercentileRank(double value);
