Cache monitor provides a view of the edge cache statistics. The following statistics are available:

ESI Processors The number of processes that are configured as edge caches.
Number of Edge Cached Entries The number of entries that are currently cached on all edge servers and processes.
Cache Hits The 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.

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.
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 The number of entries that are removed from the edge cache based on the timeout value.
Evictions The number of entries that are removed from the edge cache due to invalidations received from WAS.
