PartitionResourceMetricsRuntimeMBean (Java API Reference for Oracle WebLogic Server)

All Superinterfaces:

javax.management.DynamicMBean, javax.management.MBeanRegistration, javax.management.NotificationBroadcaster, RuntimeMBean, WebLogicMBean
```
public interface PartitionResourceMetricsRuntimeMBean
extends RuntimeMBean
```
The runtime MBean interface for partition specific resource consumption metrics. The resource meters are added lazily for a partition. Therefore, the first time these metrics are queried, it might return zero values. Subsequent gets would return non-zero values based on the resource consumption. These metrics are applicable in the context of a partition since either server start or partition creation/restart, whichever was later.

- Method Detail
  - isRCMMetricsDataAvailable
```
boolean isRCMMetricsDataAvailable()
```
    Checks whether RCM metrics data is available for this partition.
    
    Returns:
    
    true if metrics data is available
  - getCpuTimeNanos
```
long getCpuTimeNanos()
```
    Total CPU time spent measured in nanoseconds in the context of a partition.
    
    Returns:
    
    time in nanoseconds
  - getAllocatedMemory
```
long getAllocatedMemory()
```
    Total allocated memory in bytes for the partition. This metric value increases monotonically over time, it never decreases. Retained memory should be used to get current net values.
    
    Returns:
    
    number of bytes allocated
    
    See Also:
    
    which provides the values of the net memory usage over a period of time.
  - getThreadCount
```
long getThreadCount()
```
    Number of threads currently assigned to the partition.
    
    Returns:
    
    number of threads
  - getTotalOpenedSocketCount
```
long getTotalOpenedSocketCount()
```
    Total number of sockets opened in the context of a partition.
    
    Returns:
    
    total number of sockets opened
  - getCurrentOpenSocketCount
```
long getCurrentOpenSocketCount()
```
    Number of sockets currently open in the context of a partition.
    
    Returns:
    
    current number of sockets opened
  - getNetworkBytesRead
```
long getNetworkBytesRead()
```
    Total number of bytes read from sockets for a partition.
    
    Returns:
    
    total number of bytes read
  - getNetworkBytesWritten
```
long getNetworkBytesWritten()
```
    Total number of bytes written to sockets for a partition.
    
    Returns:
    
    total number of bytes written
  - getTotalOpenedFileCount
```
long getTotalOpenedFileCount()
```
    Total number of files opened in the context of a partition.
    
    Returns:
    
    total number of files opened
  - getCurrentOpenFileCount
```
long getCurrentOpenFileCount()
```
    Number of files currently open in the context of a partition.
    
    Returns:
    
    current number of files opened
  - getFileBytesRead
```
long getFileBytesRead()
```
    Total number of file bytes read in the context of a partition.
    
    Returns:
    
    total number of bytes read
  - getFileBytesWritten
```
long getFileBytesWritten()
```
    Total number of file bytes written in the context of a partition.
    
    Returns:
    
    total number of bytes written
  - getTotalOpenedFileDescriptorCount
```
long getTotalOpenedFileDescriptorCount()
```
    Total number of file descriptors opened in the context of a partition.
    
    Returns:
    
    total number of descriptors opened
  - getCurrentOpenFileDescriptorCount
```
long getCurrentOpenFileDescriptorCount()
```
    Number of file descriptors currently open in the context of a partition.
    
    Returns:
    
    current number of descriptors open
  - getRetainedHeapHistoricalData
```
java.lang.Long[][] getRetainedHeapHistoricalData()
```
    Returns a snapshot of the historical data for retained heap memory usage for the partition. Data is returned as a two-dimensional array for the usage of retained heap scoped to the partition over time. Each item in the array contains a tuple of [timestamp (long), retainedHeap(long)] values.
    
    Returns:
    
    snapshot of historical heap memory
  - getCpuUtilizationHistoricalData
```
java.lang.Long[][] getCpuUtilizationHistoricalData()
```
    Returns a snapshot of the historical data for CPU usage for the partition. CPU Utilization percentage indicates the percentage of CPU utilized by a partition with respect to available CPU to Weblogic Server. Data is returned as a two-dimensional array for the CPU usage scoped to the partition over time. Each item in the array contains a tuple of [timestamp (long), cpuUsage(long)] values.
    
    Returns:
    
    snapshot of historical CPU usage
