             Summary: AMS : Allow for certain metrics to skip aggregation determined by client
                 Key: AMBARI-18125
                 URL: https://issues.apache.org/jira/browse/AMBARI-18125
             Project: Ambari
          Issue Type: Task
          Components: ambari-metrics
    Affects Versions: 2.4.0
            Reporter: Aravindan Vijayan
            Assignee: Aravindan Vijayan
             Fix For: 2.5.0


_Example_: Per disk metrics / host static info (no aggregation across hosts)

The client should be able to submit a request which dimension should be skipped.
The metadata can store this info and allow the SELECT query projection to skip a chunk of these metrics based on what aggregation is working.
For now only across host skipping makes sense and the client part can be put in later.

*Note*:
Sub-task, de-normalize disk metrics so that user can find out disk per host.
Grafana implication: The non-aggregated metrics can obviously be visualized only on the templatized / host dashboard
