             Summary: Add random jitter to monitor’s scheduling interval.
                 Key: SAMZA-1588
                 URL: https://issues.apache.org/jira/browse/SAMZA-1588
             Project: Samza
          Issue Type: Improvement
            Reporter: Shanthoosh Venkataraman
            Assignee: Shanthoosh Venkataraman


We’ve observed in LinkedIn execution environments that, all the monitors running on the YARN node-manager machines hitting an external service at the same time based upon the configured monitor scheduling interval.

 To eliminate unnecessary monitor execution spike and congestion caused to an external service at the same time, it’s essential to add a random jitter to the monitor scheduling interval.

Creating this ticket for book-keeping purposes to track these changes.
