Subject Re: [question] command line to get replication metrics info
Date Mon, 19 Aug 2013 21:44:59 GMT
See what the "status" command calls in the shell, I would suggest following
similar flows.

Maybe you could also add to it, like a "status 'replication'" option,
instead of having a different command.
