how long a Zookeeper server is unavailable between elections, quorum packet size and time
spent in the queue, aggregate request states/flow, request throttle, sync processor queue

final request processor read/write times, watch manager cnxn/path counts, latencies at different
points in pipeline for commits/informs, split up request type counters for more request types,
export sum metrics for all AvgMinMax counters, per-connection watch fired counts, ack latency
for each follower, percentile metrics to zeus latency counters, proposal count, number of
outstanding changes,  snapshot and txns loading time during startup, number of non-voting
