Edge cache statistics

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.
    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. 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 WebSphere Application Server.
