WebSphere Dynamic Cache Stats interface.
Dynamic cache stats are structured as follows in the PMI tree:
<server>
|
|__Dynamic Caching+
|
|__Servlet cache+
|
|__<cache_A>
|
|__Templates+
|__<template_1>
|__Object cache+
|
|__<cache_1>
|__<cache_2>
+ indicates logical group
StatDescriptor
is used to locate and access particular Stats in the PMI tree.
Example:
new StatDescriptor (new String[] {WSDynamicCacheStats.NAME, WSDynamicCacheStats.SERVLET_CACHE_GROUP, "cache_A", WSDynamicCacheStats.TEMPLATE_GROUP, "Template_1"});
new StatDescriptor (new String[] {WSDynamicCacheStats.NAME, WSDynamicCacheStats.OBJECT_CACHE_GROUP, "cache_1"});
