CodaHale metrics for Solr 6?

Anybody using the CodaHale metrics.jetty9.InstrumentedHandler? It looks a lot like something we built for our own use with Solr 4.

Expanding on my comment on the ticket, I’m really quite happy with using codahale/dropwizard metrics with Solr. I don’t know if I’m comfortable just sharing a screenshot of the resulting grafana dashboard, but I’ve got, per-host:

- Percentile latencies and rates for GET vs POST (which in solrcloud generally maps to top-level-query vs shard-request & update) (From the jetty-metrics plugin)
- Log rates by log level (from the logging-metrics plugin)
- GC time (from the jvm-metrics plugin)
- Thread counts (same)
- Percentile latencies and rates per query “performance class” (from my metrics-aware backup request handler - https://github.com/whitepages/SOLR-4449) 
- Backup request rates (same)

I’ve been agitating the idea of getting metrics more tightly integrated for at least a year, maybe longer. I’ve been using the jetty metrics plugin since at least Solr 4.9, and have upgraded and re-added it at least twice.

    It seems like this would be a solution for SOLR-4735, which has been open for 3.5 years.
