Package oracle.kv.mgmt.jmx

Interface StorageNodeMXBean

  • public interface StorageNodeMXBean
    This MBean represents the Storage Node's operational parameters.

    The information that is published to the <kvroot>/log/<storename>.stats and <kvroot>/log/<storename>.perf files is also available through this MBean, via the standard javax.management.Notification mechanism. An application may subscribe to notifications from a given Storage Node by adding a notification listener with the name "Oracle NoSQL Database:type=StorageNode"

    1. Notifications of type "oracle.kv.repnode.opmetric" contain a user data payload that is the full listing of performance metrics for a given RN. The stats are a string in JSON form, and are obtained via Notification.getUserData().
    2. Notifications of type "oracle.kv.repnode.envmetric" contain a user data payload that is the full listing of detailed stats for a given RN. The stats are a string in JSON form and are obtained via Notification.getUserData().
