Edge cache statistics

Cache monitor provides a view of these edge cache statistics.

• 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 WAS will result in a miss. Every request for a template that does not have a cache policy on WAS 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.

  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 WAS.
