Interface WSThreadPoolStats



  • public interface WSThreadPoolStats
    WebSphere Thread Pool Stats interface. Thread pool stats are structured as follows in the PMI tree:

    <server>
    |
    |__Thread Pools+
      |
      |__<threadPool_A>
      |__<threadPool_B>

    + indicates logical group

    StatDescriptor is used to locate and access particular Stats in the PMI tree.
    Example:

    1. StatDescriptor that represents the thread pool stats logical group: new StatDescriptor (new String[] {WSThreadPoolStats.NAME});
    2. StatDescriptor that represents the stats for <threadPool_B> thread pool: new StatDescriptor (new String[] {WSThreadPoolStats.NAME, "threadPool_B"});
