WSDynamicCacheStats (IBM WebSphere Application Server, Release 9.0)

```
public interface WSDynamicCacheStats
```
WebSphere Dynamic Cache Stats interface. Dynamic cache stats are structured as follows in the PMI tree:

<server>
|
|__Dynamic Caching+
  |
  |__<Servlet: instance1>
    |__Templates+
      |__<template_1>
      |__<template_2>
    |__Disk+
      |__<Disk Offload Enabled>
  |
  |__<Object: instance2>
    |__Object Cache+
      |__<Counters>

+ indicates logical group

StatDescriptor is used to locate and access particular Stats in the PMI tree.
Example:
1. StatDescriptor to represent statistics for cache Servlet: instance1 templates group Template_1: new StatDescriptor (new String[] {WSDynamicCacheStats.NAME, "Servlet: instance1", WSDynamicCacheStats.TEMPLATE_GROUP, "Template_1"});
2. StatDescriptor to represent statistics for cache Servlet: instance1 disk group Disk Offload Enabled: new StatDescriptor (new String[] {WSDynamicCacheStats.NAME, "Servlet: instance1", WSDynamicCacheStats.DISK_GROUP, WSDynamicCacheStats.DISK_OFFLOAD_ENABLED});
3. StatDescriptor to represent statistics for cache Object: instance2 object cache group Counters: new StatDescriptor (new String[] {WSDynamicCacheStats.NAME, "Object: instance2", WSDynamicCacheStats.OBJECT_GROUP, WSDynamicCacheStats.OBJECT_COUNTERS});
Note: cache instance names are prepended with cache type ("Servlet: " or "Object: ").
