As we review replacing Folsom with Exometer for metrics collection within Riak and Riak Core, we must verify that Exometer's performance overhead is less than or equal to Folsom. We also need to understand the impact of Exometer's measurements as load increases to ensure that its overhead remains constant. In order to measure their respective overhead, Riak will be configured in the following manner to isolate metrics collection operations from other Riak work (e.g. GETs, PUTs, DELETEs, handoffs, etc):

• Ring size: 32
• Backend: yessir
• AAE, Search, Yokozuna, and Strong Consistency disabled

In order to measure overhead, one instance of Basho Bench (b_b) executed the metrics_punisher configuration attached to this gist against a Riak cluster. A second instance of b_b will simultaneously execute the stats_query configured attached to this gist against the cluster querying the stats endpoint. Based on discussions with Rus
