After upgrading to Security Analytics 8.3.1, the Legacy Oldest Meta Data is not populating on the Capture Summary page when connected to the Central Manager. If directly connected to the sensor, the data shows up correctly.
Security Analytics 8.3.1
This was caused by a condition where the 'trino' database service would continuously crash, preventing the population of the correct data.
This has been fixed in Security Analytics 8.3.1 NSR-1, which is available by going to the "My Download" section in the Support Portal and selecting Security Analytics and then version 8.3.1.
