    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.

    :type FleetId: string
    :param FleetId: [REQUIRED]
            Unique identifier for a fleet to get event logs for.
            

    :type StartTime: datetime
    :param StartTime: Earliest date to retrieve event logs for. If no start time is specified, this call returns entries starting from when the fleet was created to the specified end time. Format is a number expressed in Unix time as milliseconds (ex: '1469498468.057').

    :type EndTime: datetime
    :param EndTime: 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').

    :type Limit: integer
    :param Limit: Maximum number of results to return. Use this parameter with NextToken to get results as a set of sequential pages.

    :type NextToken: string
    :param NextToken: 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 specify the start of the result set, do not specify a value.
