In-Depth Information
Under the
liferay-multi-vm-clustered
tree node, we can find all the cache
instances as subnodes. Click on the
Attributes
subnode of the specific cache.
The system will display cache statistics of the selected cache instance as shown
in the following screenshot:
Cache statistics provide information of various attributes, but here are the key
attributes that should be monitored during a load test:
•
ObjectCount
: This attribute tells us how many objects there are in the cache.
•
OnDiskHits
: This attribute tells us how many requests are successful in
locating objects from a filesystem-based cache. This attribute is useful if
we enabled overflow to the disk attribute of the cache instance.
•
InMemoryHits
: This attribute tells us how many requests are successful in
retrieving objects from an in-memory cache.
•
CacheHits
: This attribute tells us how many requests are successful in
retrieving objects from the cache. It includes both in-memory and
disk-based caches.
•
CacheMisses
: This attribute tells us how many requests are unsuccessful in
retrieving objects from the cache.
