Attributes (11)

  • busy-task-thread-count An estimate of busy threads in the task worker thread pool
    • Attribute Value
    Type INT
    Nillable false
    Expressions Allowed false
    Storage runtime
    Access Type metric
    Stability default
  • core-pool-size Minimum number of threads to keep in the underlying thread pool even if they are idle. Threads over this limit will be terminated over time specified by task-keepalive attribute.
    • Attribute Value
    Type INT
    Nillable false
    Expressions Allowed false
    Storage runtime
    Access Type metric
    Stability default
  • io-thread-count I/O thread count
    • Attribute Value
    Type INT
    Nillable false
    Expressions Allowed false
    Storage runtime
    Access Type metric
    Stability default
  • io-threads Specify the number of I/O threads to create for the worker. If not specified, a default will be chosen, which is calculated by cpuCount * 2
    • Attribute Value
    Type INT
    Nillable true
    Expressions Allowed true
    Min 0
    Max 2,147,483,647
    Storage configuration
    Access Type read-write
    Restart Required all-services
    Stability default
  • max-pool-size The maximum number of threads allowed in the worker task thread pool. Depending on the pool implementation, when this limit is reached tasks which cannot be queued may be rejected. This can be configured using the 'task-max-threads' attribute; see the description of that attribute for details on how this value is determined.
    • Attribute Value
    Type INT
    Nillable false
    Expressions Allowed false
    Storage runtime
    Access Type metric
    Stability default
  • queue-size An estimate of the number of tasks in the worker queue.
    • Attribute Value
    Type INT
    Nillable false
    Expressions Allowed false
    Storage runtime
    Access Type metric
    Stability default
  • shutdown-requested True is shutdown of the pool was requested
    • Attribute Value
    Type BOOLEAN
    Nillable false
    Expressions Allowed false
    Storage runtime
    Access Type read-only
    Stability default
  • stack-size The stack size (in bytes) to attempt to use for worker threads.
    • Attribute Value
    Default Value 0
    Type LONG
    Nillable true
    Expressions Allowed true
    Min 0
    Max -1
    Storage configuration
    Access Type read-write
    Restart Required all-services
    Stability default
  • task-core-threads Specify the starting number of threads for the worker task thread pool.
    • Attribute Value
    Default Value 2
    Type INT
    Nillable true
    Expressions Allowed true
    Min 0
    Max 2,147,483,647
    Storage configuration
    Access Type read-write
    Restart Required no-services
    Stability default
  • task-keepalive Specify the number of milliseconds to keep non-core task threads alive.
    • Attribute Value
    Default Value 60000
    Type INT
    Nillable true
    Expressions Allowed true
    Min 0
    Max 2,147,483,647
    Storage configuration
    Access Type read-write
    Restart Required no-services
    Stability default
  • task-max-threads Specify the maximum number of threads for the worker task thread pool.If not set, a default value used which is calculated by the formula cpuCount * 16,as long as the MaxFileDescriptorCount jmx property allows that number; otherwise the calculation takes that max into account and adjusts accordingly.
    • Attribute Value
    Type INT
    Nillable true
    Expressions Allowed true
