3.3 period

The period configuration item specifies how long to wait between pings. The units are (integer) seconds. If there is one integer, ‘alive’ uses it as a fixed period. If there are two, the first must be less than or equal than the second, and ‘alive’ chooses a random number between (inclusively) the two.
