Gets statistics from the named TAP connections.
Description
TAP is an internal protocol that streams information about data changes between cluster nodes.
The command cbstats tapagg
is used to get statistics from named TAP connections which are logically grouped and aggregated together by prefixes.
For example, if all of your TAP connections started with rebalance_
or replication_
, you could call cbstats tapagg
to request stats grouped by the prefix starting with .
This would return a set of statistics for
rebalance
and a set for replication
.
TAP aggregated stats
Aggregated TAP stats allow named TAP connections to be logically grouped and aggregated together by prefixes.
For example, if all of your TAP connections started with rebalance_
or replication_
, you could call cbstats tapagg
to request stats grouped by the prefix starting with .
This returns a set of statistics for rebalance and a set for replication.
