Hi Bookkeeper Community, I created an issue [0] yesterday to discuss exposing Rocks DB metrics via the bookie's /metrics endpoint. My primary focus is exposing metrics that will help verify that the database is sufficiently provisioned and to help show the real time interactions between bookkeeper and Rocks DB. I created the issue focused on cache metrics, but there might be other valuable metrics to expose.
Has anyone looked into these metrics? Is there any reason we shouldn't expose them? Adding them may require some modifications to the StatsLogger's interface because it does not currently support externally managed counters. If there isn't an objection, I'll continue looking at which metrics to expose and how to integrate them into the StatsLogger. Thanks, Michael [0] https://github.com/apache/bookkeeper/issues/3442
