After upgrading AAI to 24.1.x or later the Jobstream Run Maintenance setting has been increase to 396 days, when it was previously 180 days.
AAI 24.1.x or later
The increase in Jobstream Run History was by design to allow users to see a full 12+ months in the new "Jobstream Performance Over Last Year" dashboard.
This will require some time to allow the full 12+ months of history to populate.
If you have database storage concerns this value can be lowered, but you will not be able to see a full 12+ months in the dashboard mentioned above.
