Edge cache statistics

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 that

  • The initial ESI request for a template that has a cache policy on WebSphere Application Server will result in a miss.

  • Every request for a template that does not have a cache policy on WebSphere Application Server will result 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.

  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 WAS.
