-| Autofailover|**autofailover_poll_interval** | integer | 500 | How often to check for failure of nodes (milliseconds)
-| Autofailover|**autofailover_node_retry** | integer | 2 | When failure is detected, retry this many times before initiating failover
-| Autofailover|**autofailover_sleep_time** | integer | 1000 | Interval between retries (milliseconds)
+| Autofailover|**autofailover_poll_interval** | integer | *500* | How often to check for failure of nodes (milliseconds)
+| Autofailover|**autofailover_node_retry** | integer | *2* | When failure is detected, retry this many times before initiating failover
+| Autofailover|**autofailover_sleep_time** | integer | *1000* | Interval between retries (milliseconds)
+| Autofailover|**autofailover_perspective_sleep_time** | integer | *20000* | Interval between lag reads for failed nodes from surviving nodes. If greater
+ | than zero any observation that nodes have failed is checked from surviving nodes
+ | perspective by checking if lag times are extending. This does not guarantee 100%
+ | the nodes are down but if set to a large enough interval can back up our observation.
+| Autofailover|**autofailover_majority_only** | boolean | *false* | Only fail over if the quantity of surviving nodes is greater than the quantity of
+ | failed nodes. Intended to be used to prevent a split-brain scenario in
+ | conjunction with some other logic to monitor and fence off the old origin if it
+ | is in the minority.
+| Autofailover|**autofailover_is_quorum** | boolean | *false* | If this script is running on a separate host set to true to treat it as a quorum
+ | server. Effectively increments sum of surviving nodes when calculating the
+ | majority above.
