    public interface ThreadPoolStats
extends org.glassfish.external.statistics.Stats
    Stats interface for the monitorable attributes of the a generic ThreadPool. This combines the statistics that were exposed in 7.0 with the new ones. In 8.0, the generic Thread Pool that can be used by any component in the server runtime is introduced.

        an instance of CountStatistic

      • getNumberOfBusyThreads

        org.glassfish.external.statistics.CountStatistic getNumberOfBusyThreads()
        Returns the number of busy threads, as an instance of CountStatistic.
        Returns:
        an instance of CountStatistic

      • getAverageWorkCompletionTime

        org.glassfish.external.statistics.RangeStatistic getAverageWorkCompletionTime()
        Returns the statistical information about the average completion time of a work item in milliseconds.
        Returns:
        an instance of RangeStatistic

      • getTotalWorkItemsAdded
