Duplicate stats similar to those found in "host"/Server/Statistics/Eventing Stats: "function" as found in https://issues.couchbase.com/browse/MB-26581 an Eventing "function" is being worked on.
Basically make the UI work for Eventing TAB similar to the Indexes TAB (refer to attachment)
As per Rob Ashcom "Adding the stats is not a big deal from the UI POV (i.e. not difficult or mysterious)"
To enable this, Eventing needs to provide ability to aggregate stats from all eventing nodes, after which it can be exposed by UI.
