This parameter specifies the duration in hours for which the FeedNotificationsRateLimit value is valid.

Default: 1

Rate limit counters are reset after FeedNotificationsRateLimitDuration number of hours elapses. This setting is only applied when FeedNotificationsRateLimiterEnabled is set to True .

For example, if FeedNotificationsRateLimiterEnabled is True , and if FeedNotificationsRateLimit=5 and FeedNotificationsRateLimitDuration=1, the effective rate limit is 5 hits per hour. This means that after sending 5 notifications for a particular IOC in a given feed, no more notifications are sent for the rest of the hour.
