pt-replica-find connects to a MySQL replication master and finds its slaves.
pt-replica-find connects to a MySQL replication source and finds its replicas.
Currently the only thing it can do is print a tree-like view of the replication
hierarchy.

The source host can be specified using one of two methods. The first method is
to use the standard connection-related command line options:

or L<"--user">.

The second method to specify the source host is a DSN. A DSN is a special
syntax that can be either just a hostname (like C<server.domain.com> or

METHOD USES
=========== ==================
processlist SHOW PROCESSLIST
hosts SHOW SLAVE HOSTS
none Do not find slaves
hosts SHOW REPLICAS (SHOW SLAVE HOSTS before MySQL 8.1)
none Do not find replicas
The processlist method is preferred because SHOW SLAVE HOSTS is not reliable.
The processlist method is preferred because SHOW REPLICAS is not reliable.
However, the hosts method is required if the server uses a non-standard
port (not 3306). Usually pt-replica-find does the right thing and finds
the slaves, but you may give a preferred method and it will be used first.
If it doesn't find any slaves, the other methods will be tried.
