The EclipseLink PeformanceMonitor has been extended to support a custom Ambari Database Metrics source. It provides us with monitoring data per entity and per operation on the entity. Applicable entities can be found in the package - org.apache.ambari.server.orm.entities.
The Performance Monitor provides 2 kinds of metrics -
...
In addition to the Counter & Timer metrics collected from EclipseLink, a computed metric of Timer/Counter (divided by) is also sent. This metrics provides the average time taken for an operation across time.
For example, if
Counter Metric : Counter.ReadAllQuery.HostRoleCommandEntity = 10000
Timer Metric : Timer.ReadAllQuery.HostRoleCommandEntity = 50
Computed Metric (Avg time for the operation) : ReadAllQuery.HostRoleCommandEntity = 200 (10000 div by 50)
As seen above, the computed metric name will be the same as the Timer & Counter metric except without the 'Timer.' / 'Counter.' prefix.
