All,

I am trying to use recursion method with pt-table-checksum using hosts method. The documentation says, “The hosts method requires replicas to be configured with report\_host, report\_port, etc”.

Where do I define these parameters and what do I do if there are more than 1 slave? Please help me if anyone has done with some detailed steps.

FYI, I have tungsten replication between the servers.

Thanks.
