> Issue Type: Improvement
> Affects Versions: 1.8.0
> Reporter: William Berkeley

> Labels: roadmap-candidate, supportability

> KUDU-2597 tracks adding a tool to parse the metrics logs. We should also add
> (probably as Python scripts) some tools for analyzing the metrics logs:
> * Finding tablets with unusual performance characteristics: longest
> apply|prepare|replicate|write|updateconsensus times
> * Finding servers with the most disk activity
> * Finding servers with slows scanners
> * Finding replicas that are largest on disk or in-memory
> * Characterizing workloads of tables and tablets
> (insert/upserts/deletes/updates/duplicate key inserts/pk lookups + times/op)
> * Compaction (average height, delta size, compaction times)
> * Log performance (append latency, sync latency, throughput)
> Some of this can be rules-based, i.e. if metric X is > constant A) and some
> should be pattern-based (most tablets' histograms look different than this
> tablet's).
