Jun Rao commented on KAFKA-604:
-------------------------------
The patch no longer applies. We should probably also add the following metrics
in the Producer:
1. Serialization time: time to encoder each event.
2. Handle time: time to handle one or a batch of events, which includes
serialization time, request sending time, and retry time.
> Add missing metrics in 0.8

> Key: KAFKA-604
> URL: https://issues.apache.org/jira/browse/KAFKA-604
> Project: Kafka
> Issue Type: Bug
> Components: core
> Affects Versions: 0.8
> Reporter: Jun Rao
> Attachments: kafka_604_v1.patch, kafka_604_v2.patch

> Original Estimate: 24h
> Remaining Estimate: 24h

> It would be good if we add the following metrics:
> Producer: droppedMessageRate per topic
> ReplicaManager: partition count on the broker
> FileMessageSet: logFlushTimer per log (i.e., partition). Also, logFlushTime
> should probably be moved to LogSegment since the flush now includes index
> flush time.
