Our data retention policy for events sent to the event hubs is 7 days.
The maximum amount of time we will store events within your event hub is 7 days, by the minute. For example, if the time now is 10:15 on Jan 8, the date time of the last alert available to be retrieved in the event hub will be 10:15 on Jan 1.
Please note that due to the data retention policy, we can only provide limited support on flight events within your event hub that was streamed more than 7 days ago. If you encounter issues with a specific event and require support, please retrieve the event and log them in an accessible location as we will not be able to identify a specific update within your event hub after it has been deleted.
