Symptom: Certain container level metrics have incorrect values when elasticity is enabled. Metrics affected: chose-object, num-envelopes, process-calls, messages-chosen. Cause: With elasticity enabled, a container may process only some of the messages of an SSP and not all of the messages in the SSP. the messages processed belong to the key buckets within the container's model. However, pre-elasticity container level metrics counted the messages per ssp. Changes: Adapt SystemConsumers and RunLoop to account for key buckets. SystemConsumers keeps track of all the SSP(with key buckets) registered with it by the RunLoop and increments only the metrics only if the message belongs to this SSP set. Tests: added unit tests to verify correct values for metrics API changes: None Usage/Upgrade instructions: None -- This is an automated message from the Apache Git Service.
