sends a PING command right after establishing the connection.

Redis Sentinel cluster client
>>> from redis.sentinel import Sentinel
>>> sentinel = Sentinel([('localhost', 26379)], socket_timeout=0.1)
>>> master = sentinel.master_for('mymaster', socket_timeout=0.1)

``sentinels`` is a list of sentinel nodes. Each node is represented by
a pair (hostname, port).
``min_other_sentinels`` defined a minimum number of peers for a sentinel.
When querying a sentinel, if it doesn't meet this threshold, responses
from that sentinel won't be considered valid.
``sentinel_kwargs`` is a dictionary of connection arguments used when
connecting to sentinel instances. Any argument that can be passed to
a normal Redis connection can be specified here. If ``sentinel_kwargs`` is
not specified, any socket_timeout and socket_keepalive options specified
in ``connection_kwargs`` will be used.
``connection_kwargs`` are keyword arguments that will be used when
establishing a connection to a Redis server.

Execute Sentinel command in sentinel nodes.
once - If set to True, then execute the resulting command on a single
node at random, rather than across the entire sentinel cluster.

to the service labeled ``service_name``.
Returns a pair (address, port) or raises MasterNotFoundError if no
master is found.

Returns a redis client instance for the ``service_name`` master.
A :py:class:`~redis.sentinel.SentinelConnectionPool` class is
used to retrieve the master's address before establishing a new
connection.
NOTE: If the master's address has changed, any cached connections to
the old master are closed.
By default clients will be a :py:class:`~redis.Redis` instance.
Specify a different class to the ``redis_class`` argument if you
desire something different.
The ``connection_pool_class`` specifies the connection pool to
use. The :py:class:`~redis.sentinel.SentinelConnectionPool`
will be used by default.
All other keyword arguments are merged with any connection_kwargs
passed to this class and passed to the connection pool as keyword
arguments to be used to initialize Redis connections.
