StorageNodeMXBean (Oracle NoSQL Database API)

```
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().

- Method Detail
  - getSnId
```
int getSnId()
```
    Returns the StorageNodeId number of this Storage Node.

```
String getServiceStatus()
```
    Returns the reported service status of the Storage Node.
  - isHostingAdmin
```
boolean isHostingAdmin()
```
    Returns true if this Storage Node hosts an Admin instance.
  - getRootDirPath
```
String getRootDirPath()
```
    Returns the pathname of the store's root directory.

```
    Returns the number of log files that are kept.
  - getMemoryMB
```
int getMemoryMB()
```
    Returns the amount of memory known to be available on this Storage Node, in megabytes.
  - getNumCPUs
```
int getNumCPUs()
```
