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:
new StatDescriptor (new String[] {WSDynamicCacheStats.NAME, "Servlet: instance1", WSDynamicCacheStats.TEMPLATE_GROUP, "Template_1"});
new StatDescriptor (new String[] {WSDynamicCacheStats.NAME, "Servlet: instance1", WSDynamicCacheStats.DISK_GROUP, WSDynamicCacheStats.DISK_OFFLOAD_ENABLED});
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: ").
