XDCR metrics

Hello,

just had to double check something for a customer regarding a XDCR statistic and would propose the following change:

• The Admin Console mentions the metrics 'wtavg_docs_latency' and 'wtavg_meta_latency' for an outgoing XDCR connection

The documentation does not mention these metrics here: http://developer.couchbase.com/documentation/server/current/rest-api/rest-xdcr-statistics.html

It's not clear for me if these are just the 'docs_latency_wt' and 'meta_latency_wt' ones. However, I tried out to access 'docs_latency_wt' and 'meta_latency_wt' without success, whereby the access to e.g. 'wtavg_docs_latency' was successful.

http://192.168.7.141:8091/pools/default/buckets/source/stats/replications%2F02fc9909c035a8ec735d3e74b1d0f09d%2Fsource%2Ftarget%2Fwtavg_docs_latency

Please double check which of the documented statistics are still valid. The same time I think that at least the stats those are exposed via the Admin UI should be added to the documentation page mentioned above.

Especially for the latency statistics it would be also nice to have a bit more context what is included in the latency. What does 'Weighted average latency for sending replicated changes to destination cluster.' actually mean? Which amount of changes (one operation, one batch, all of them)?. Is the round trip included? Is this the network latency only?

Regards,
David
