  ################################ LATENCY MONITOR ##############################
  
  # The Redis latency monitoring subsystem samples different operations
  # at runtime in order to collect data related to possible sources of
  # latency of a Redis instance.
  #
  # Via the LATENCY command this information is available to the user that can
  # print graphs and obtain reports.
  #
  # The system only logs operations that were performed in a time equal or
  # greater than the amount of milliseconds specified via the
  # latency-monitor-threshold configuration directive. When its value is set
  # to zero, the latency monitor is turned off.
  #
  # By default latency monitoring is disabled since it is mostly not needed
  # if you don't have latency issues, and collecting data has a performance
  # impact, that while very small, can be measured under big load. Latency
  # monitoring can easily be enabled at runtime using the command
  # "CONFIG SET latency-monitor-threshold <milliseconds>" if needed.

  ############################# EVENT NOTIFICATION ##############################
  
  # Redis can notify Pub/Sub clients about events happening in the key space.
  # This feature is documented at http://redis.io/topics/notifications
  #
  # For instance if keyspace events notification is enabled, and a client
  # performs a DEL operation on key "foo" stored in the Database 0, two
  # messages will be published via Pub/Sub:
  #
  # PUBLISH __keyspace@0__:foo del
  # PUBLISH __keyevent@0__:del foo
  #
  # It is possible to select the events that Redis will notify among a set
  # of classes. Every class is identified by a single character:
  #
  #  K     Keyspace events, published with __keyspace@<db>__ prefix.
  #  E     Keyevent events, published with __keyevent@<db>__ prefix.
  #  g     Generic commands (non-type specific) like DEL, EXPIRE, RENAME, ...
  #  $     String commands
  #  l     List commands
  #  s     Set commands
  #  h     Hash commands
  #  z     Sorted set commands
  #  x     Expired events (events generated every time a key expires)
  #  e     Evicted events (events generated when a key is evicted for maxmemory)
  #  A     Alias for g$lshzxe, so that the "AKE" string means all the events.
  #
  #  The "notify-keyspace-events" takes as argument a string that is composed
  #  of zero or multiple characters. The empty string means that notifications
  #  are disabled.
  #
  #  Example: to enable list and generic events, from the point of view of the
  #           event name, use:
  #
  #  notify-keyspace-events Elg
  #
  #  Example 2: to get the stream of the expired keys subscribing to channel
  #             name __keyevent@0__:expired use:
  #
  #  notify-keyspace-events Ex
  #
  #  By default all notifications are disabled because most users don't need
  #  this feature and the feature has some overhead. Note that if you don't
  #  specify at least one of K or E, no events will be delivered.
