Statistics of a pipeline which may or may not be running.

the number of docs that failed conflict resolution on the source cluster side due to optimistic replication.

optimistic replication replated statistics.

the number of docs processed by pipeline.

the number of docs written/sent to target cluster.

Memory related statistics.

TIME_COMMITTING_METRIC = "time_committing"rate.

latency caused by bandwidth throttling.

latency caused by throughput throttling.

keys for metrics that do not monotonically increase during replication, to which the "going backward" check should not be applied.

factors affecting bandwidth limit of the current node, which could be updated through UpdateSettings() call.

keys for metrics in overview.

stats to clear when replications are paused 1.

stats to initialize for paused replications that have never been run -- mostly the stats visible from UI.

the fixed user agent string for connections to collect stats for paused replications it is possible to construct the user agent string dynamically by adding source and target bucket info to it it would cause many string re-allocations, though.

BandwidthThrottler limits bandwidth usage of replication.

StatisticsManager mount the statics collector on the pipeline to collect raw statsIt does stats correlation and processing on raw stats periodically (controlled by publish_interval), then stores the result in expvarThe result in expvar can be exposed to outside via different channels - log or to ns_server.

Stats per vbucket.
