             Summary: Add log cleaner metrics
                 Key: KAFKA-1327
                 URL: https://issues.apache.org/jira/browse/KAFKA-1327
             Project: Kafka
          Issue Type: Improvement
            Reporter: Jay Kreps
            Assignee: Jay Kreps


The proposal would be to add the following metrics:
1. Compaction I/O rate (MB/sec) across all threads (read+write)
2. Data size on disk per partition
3. Max dirty ratio across all logs
4. Max buffer use from all compactions so far
5. Survivorship ratio (# records recopied / total records)
