Cache monitor provides a view of the edge cache statistics.
The following statistics are available:
ESI Processors . Number of processes configured as edge caches.
Number of Edge Cached Entries . Number of entries currently cached on all edge servers and processes.
Cache Hits . Number of requests that match entries on edge servers.
Cache Misses By URL. A cache policy does not exist on the edge server, for the requested template.
Note:
The initial ESI request for a template that has a cache policy on WebSphere Application Server results in a miss.
Every request for a template that does not have a cache policy on WebSphere Application Server results in a miss by URL on the edge server.
Cache Misses By Cache ID . The policy for the requested template exists on the edge server, and a cache ID is created, based on the ID rules and the request attributes, but the cache entry for this ID does not exist.
Note: If the policy exists on the edge server for the requested template,
but a cache ID match is not found, based on the ID rules and the request attributes,
it is not treated as a cache miss.
Cache Timeouts . Number of entries removed from the edge cache,
based on the timeout value.
Evictions . Number of entries removed from the edge cache, due to invalidations received from WebSphere Application Server.
