Hello all,

Please help me with the error.

Checking if all tables can be checksummed …  
Starting checksum …  
Cannot connect to P=3306,h=slave,p=…,u=ptc  
Diffs cannot be detected because no slaves were found. Please read the --recursion-method documentation for information.

Should i configure something in Percona tool configuration file ?

Can anyone share the steps .

Thanks
