"Apache Storm version 1.2 introduced a new metrics system for reporting internal statistics (e.g. acked, failed, emitted, transferred, disruptor queue metrics, etc.) as well as a new API for user defined metrics.
The new metrics system is based on Dropwizard Metrics."
Currently at my company we're still using a storm version that does not have any metric reporter (1.1.x), we're planning to move to 2.2 version, however since, we've been using codahale metrics reporter to track some events on storm and since the newer versions already include this, it means that we have to change every topology we already have in production.
It would be nice, that this dependency inside of storm could be shaded in order to ease any migration, or at least without a lot of refactoring on the topologies, I assume this problem must be similar in other companies, and storm already does this for other artifacts.
I would be happy to perform the necessary changes in order to accomplish this.
