Description |
Measurement
Unit |
Interpretation |
| Client_requests |
The number of requests for cacheable objects that were generated by applications running on the application server, since the last measurement period |
Number
|
|
| Explicit_invalidation |
The number of explicit invalidations since the last measurement period |
Number
|
|
| Hits_on_memory |
The number of requests for cacheable objects that were served from memory since the last measurement period |
Number
|
While direct disk reads cause an increase in processing overheads, memory reads are less expensive. Therefore, a high value of this measure is indicative of the good health of the server. |
| Hits_on_disk |
The number of requests for cacheable objects that are served from the disk since the last measurement period |
Number
|
Reading from the disk is more expensive than reading from the cache. Therefore, ideally, this value should be low.
|
| Memory_cache_entry |
The number of in-memory cache entries since the last measurement period |
Number
|
|
| Max_memory_cache_entry |
The maximum number of in-memory cache entries |
Number
|
|
| Miss_count |
The number of requests for cacheable objects that were not served from the cache since the last measurement period |
Number
|
Ideally, this value should be low. |
| Remote_creation |
The number of cache entries that were received from co-operating dynamic caches, since the last measurement period |
Number
|
|
| Remote_hits |
The number of requests for cacheable objects that were served from other JVMs within the replication domain, since the last measurement period |
Number
|
|
| Timeout_invalidation |
The number of cache entries that were removed from the memory and disk because of a timeout, since the last measurement period |
Number
