Cache Metricset retrieves the JMX key Catalina:context=*,host=*,name=Cache,type=WebResourceRoot
. It exposes the following metrics:
-
tomcat.cache.mbean
: Mbean that this event is related to. -
tomcat.cache.hit.total
: The number of requests for resources that were served from the cache. -
tomcat.cache.size.total.kb
: The current estimate of the cache size in kB -
tomcat.cache.size.max.kb
: The maximum permitted size of the cache in kB -
tomcat.cache.lookup.total
: The number of requests for resources -
tomcat.cache.ttl.ms
: The time-to-live for cache entries in milliseconds
This is a default metricset. If the host module is unconfigured, this metricset is enabled by default.
For a description of each field in the metricset, see the exported fields section.
