Interface MethodCallStatisticsMXBean

@MXBean public interface MethodCallStatisticsMXBean
Exposes statistics on method call timings and rates to JMX monitoring.

  • Method Details

    • getCallCount

      long getCallCount()
      The total number of times that this method has been called since monitoring began.

    • getTimeUnit

      TimeUnit getTimeUnit()
      The units used for all time measurements.

    • getMinimumTime

      long getMinimumTime()
      The minimum time that this method took to execute.

    • getMaximumTime

      long getMaximumTime()
      The maximum time that this method took to execute. This is almost always the first call to the method due to classloading and compilation overheads.

    • getMeanTime

      double getMeanTime()
      The average (mean) time that this method took to execute. In most cases, the median and percentile distributions are a more accurate reflection of system performance as the mean is influenced by outliers which typically occur initially before JIT compilation has completed.

    • getStdDeviation

      double getStdDeviation()
      The standard deviation of the average execution time.

    • getMedianTime

      long getMedianTime()
      The median (50th percentile) time taken to execute this method. 50% of all requests completed within this time.

    • get75thPercentileTime

      long get75thPercentileTime()
      The 75th percentile execution time. 75% of all requests completed within this time.

    • get90thPercentileTime

      long get90thPercentileTime()
      The 90th percentile execution time. 90% of all requests completed within this time.

    • get95thPercentileTime

      long get95thPercentileTime()
      The 95th percentile execution time. 95% of all requests completed within this time.

    • get98thPercentileTime

      long get98thPercentileTime()
      The 98th percentile execution time. 98% of all requests completed within this time.

    • get99thPercentileTime

      long get99thPercentileTime()
      The 99th percentile execution time. 99% of all requests completed within this time.

    • get99Point9thPercentileTime

      long get99Point9thPercentileTime()
      The 99.9th percentile execution time. 99% of all requests completed within this time.

    • get99Point99thPercentileTime

      long get99Point99thPercentileTime()
      The 99.99th percentile execution time. 99.99% of all requests completed within this time.

    • getPercentileDump

      String getPercentileDump()
      Gets a raw summary dump of call time percentile distribution data, suitable for plotting.

    • getUpdateIntervalMillis

      long getUpdateIntervalMillis()
      The interval at which the implementation polls for updates from the underlying performance monitoring code, in milliseconds. A value of -1 indicates continuous monitoring.

    • setUpdateIntervalMillis

      void setUpdateIntervalMillis(long intervalMillis)
      Sets the interval at which to poll for updates from the underlying performance monitoring framework.
      Parameters:
      intervalMillis - the update interval in milliseconds. Must be greater than 0.

    • reset

      void reset()
      Resets all statistics to zero.

    • getMonitoringStartTime

      Date getMonitoringStartTime()
      The timestamp at which monitoring began or the most recent call to reset().

    • getLastUpdateTime

      Date getLastUpdateTime()
      The timestamp at which the statistics were last updated.
