[jira] [Created] (SAMZA-25) Add metrics

Chris Riccomini created SAMZA-25:
------------------------------------

             Summary: Add metrics
                 Key: SAMZA-25
                 URL: https://issues.apache.org/jira/browse/SAMZA-25
             Project: Samza
          Issue Type: Bug
          Components: container, kafka, kv, yarn
    Affects Versions: 0.6.0
            Reporter: Chris Riccomini
             Fix For: 0.7.0


The latest refactor dropped a bunch of metrics. We need to re-add them.

Classes that need metrics:

* Add metrics to SamzaContainer/SamzaContainerMetrics
* Add metrics to TaskInstance/TaskInstanceMetrics
* Add metrics to TaskStorageManager
* Add metrics to MessageChooser
* Add metrics to DefaultChooser
* Add metrics to SystemConsumers
* Add metrics to SystemProducers
* Add metrics to KafkaSystemProducer
* Add metrics to KafkaSystemConsumer
* Add metrics to CachedStore
* Add metrics to LoggedStore
* Add metrics to KeyValueStorageEngine
* Add metrics to LevelDbKeyValueStore

There are probably a lot more, as well.

We definitely need msgs/sec, bytes/sec at both the container and task level. We also need reads/sec writes/sec on the stores. A lot more, as well.
