[jira] [Created] (QUARKS-11) Support for custom metrics

Victor Dogaru created QUARKS-11:
-----------------------------------

             Summary: Support for custom metrics
                 Key: QUARKS-11
                 URL: https://issues.apache.org/jira/browse/QUARKS-11
             Project: Quarks
          Issue Type: New Feature
            Reporter: Victor Dogaru
            Assignee: Victor Dogaru


Currently Quarks provides the following metrics encapsulated in Oplet implementations:
* tuple counter (number of tuples since topology submission)
* tuple meter (mean throughput and moving averages).

Additional support is needed to satisfy the following usage scenarios:
* Using metrics in lambda functions: a developer writes 
* Define oplet which encapsulates multiple metrics
* Metric naming: a logical name is assigned to a metric when a topology is declared; name is used to access the metric at run time.

For reference the initial discussion was added under this issue: https://github.com/quarks-edge/quarks/issues/117
