Jay Kreps commented on KAFKA-1327:
----------------------------------
Okay reviewboard is busted. Jun, I renamed the metrics as you suggested. I
think it is possible that I am misunderstanding the meaning of gauge and meter
because according to my understanding anything which is used per-second is a
meter so by definition the metric in the throttler is a meter. But I don't know
this library well so this may be wrong.
> Add log cleaner metrics

> 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)
