   7 # sentinel monitor <name> <ip> <redis-port> <quorum>
   8 # Tells Sentinel to monitor this slave, and to consider it in O_DOWN
   9 # (Objectively Down) state only if at least <quorum> sentinels agree.
  10 #
  11 # Note: master name should not include special characters or spaces.
  12 # The valid charset is A-z 0-9 and the three characters ".-_".

  15 # sentinel down-after-milliseconds <mymaster> <milliseconds>
  16 # Number of milliseconds the master (or any attached slave or sentinel) should
  17 # be unreachable (as in, not acceptable reply to PING, continuously, for the
  18 # specified period) in order to consider it in S_DOWN state (Subjectively
  19 # Down).
  20 #
  21 # Default is 30 seconds.

  24 # sentinel can-failover <mymaster> <yes|no>
  25 # Specify if this Sentinel can start the failover for this master.
  26 sentinel can-failover mymaster yes
  27
  28 # sentinel parallel-syncs <mymaster> <numslaves>
  29 # How many slaves we can reconfigure to point to the new slave simultaneously
  30 # during the failover. Use a low number if you use the slaves to serve query
  31 # to avoid that all the slaves will be unreachable at about the same
  32 # time while performing the synchronization with the master.
  33 sentinel parallel-syncs mymaster 1
  34
  35 # sentinel failover-timeout <mymaster> <milliseconds>
  36 # Specifies the failover timeout in milliseconds. When this time has elapsed
  37 # without any progress in the failover process, it is considered concluded by
  38 # the sentinel even if not all the attached slaves were correctly configured
  39 # to replicate with the new master (however a "best effort" SLAVEOF command
  40 # is sent to all the slaves before).
  41 #
  42 # Also when 25% of this time has elapsed without any advancement, and there
  43 # is a leader switch (the sentinel did not started the failover but is now
  44 # elected as leader), the sentinel will continue the failover doing a
  45 # "takeover".
  46 #
  47 # Default is 15 minutes.
