Goal
Be able to monitor EhCache usage in an application.
Installation
Just drop the EhCache jar. If EhCache CacheManager are already created the org.apache.sirona.agent.ehcache.EhCacheGaugeFactory will fond them and monitor them. If not you’ll need to register the gauges yourself calling Repository.Instance.addGauge() for each gauge returned by org.apache.sirona.agent.ehcache.EhCacheGaugeFactory#register.
Data monitored
The EhCache monitoring provides the following gauges for each cache:
- hit count
- miss expired count
- miss not found count
- miss count
- put added count
- put updated count
- put count
- remove count
- expired count
- evicted count
- hit ratio
And the following for each cache manager:
- cache count
- commit count
- rollback count
