Database Metrics

Working

The EclipseLink PeformanceMonitor has been extended to support a custom Ambari Database Metrics source. The Performance Monitor provides 2 kinds of metrics -

• Counter - Number of occurrences of the operation / query. For such type of metrics, the metric name will start with Counter.
• Timer - Total cumulative time spent on the operation / query. For such type of metrics, the metric name will start with Timer.
  

For example, some of the metrics being collected tothe Database Metrics Source.

• Counter.ReadObjectQuery.HostRoleCommandEntity.readHostRoleCommandEntity

• Timer.ReadAllQuery.StackEntity.StackEntity.findByNameAndVersion.ObjectBuilding
