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.
