  • Method Details

    • minSize

      int minSize()
      Return the pools minimum size.

    • maxSize

      int maxSize()
      Return the pools maximum size.

    • free

      int free()
      Return number of free connections.

    • busy

      int busy()
      Return number of busy connections.

    • waiting

      int waiting()
      Return the number of threads waiting for connections.

    • highWaterMark

      int highWaterMark()
      Return the busy connection highwater mark.

    • waitCount

      int waitCount()
      Return the number of times threads had to wait for connections.

      This occurs when the pool is full and threads are waiting for a connection.

    • hitCount

      int hitCount()
      Return the hit count against the pool.

    • totalAcquireMicros

      long totalAcquireMicros()
      Return the total time acquiring a connection from the pool.

    • totalWaitMicros

      long totalWaitMicros()
      Return the total time waiting in micros for a free connection when the pool has hit maxConnections.

      When the pool is full and threads are waiting for a connection, this is the total time spent waiting.

    • maxAcquireMicros

      long maxAcquireMicros()
      Return the max acquire time in micros.

    • meanAcquireNanos

      long meanAcquireNanos()
      Return the mean acquire time in nanos.

      This should be in the ballpark of 150 nanos.
