 * `new_host_delay` (Optional) Time (in seconds) to allow a host to boot and
     applications to fully start before starting the evaluation of monitor
     results. Should be a non negative integer. Defaults to 300.
+* `evaluation_delay` (Optional) Time (in seconds) to delay evaluation, as a non-negative integer.
+    For example, if the value is set to 300 (5min), the timeframe is set to last_5m and the time is 7:00,
+    the monitor will evaluate data from 6:50 to 6:55. This is useful for AWS CloudWatch and other backfilled
+    metrics to ensure the monitor will always have data during evaluation.
 * `no_data_timeframe` (Optional) The number of minutes before a monitor will notify when data stops reporting. Must be at
     least 2x the monitor timeframe for metric alerts or 2 minutes for service checks. Default: 2x timeframe for
     metric alerts, 2 minutes for service checks.
