-- Retrieves entries from the specified fleet's event log. You can specify a time range to limit the result set. Use the pagination parameters to retrieve results as a set of sequential pages. If successful, a collection of event log entries matching the request are returned.

--
-- * 'dfeNextToken' - Token that indicates the start of the next sequential page of results. Use the token that is returned with a previous call to this action. To start at the beginning of the result set, do not specify a value.
--
-- * 'dfeEndTime' - Most recent date to retrieve event logs for. If no end time is specified, this call returns entries from the specified start time up to the present. Format is a number expressed in Unix time as milliseconds (ex: "1469498468.057").
--
-- * 'dfeLimit' - Maximum number of results to return. Use this parameter with @NextToken@ to get results as a set of sequential pages.
