Prisma Cloud Compute: Why Registry Image Scan Result Disappears

• Registry scan result gets removed from console after 1 day.

• Prisma Cloud Compute
• SaaS 
• Self-hosted

• When the retention period configured is 1 day, the Console checks if there are any scans with a timestamp not within the last day, and decides these must have been deleted from the registry, therefore removing the scan results from the Console. Therefore when the setting was 1 day, there are results being deleted from the console.
• The CAP setting for scanning is 0, which means all the images will be scanned every time.
• When the number of registry images is too large with cap set to 0,  scanning for all the images might not be able to finish within a day. 

• Add more scanners as there is a very large amount of images to scan.
• Increase the Registry Scan Retention Days from 1 to 30 days (or a custom number which is suitable)
• Set cap on the number of images to scan and/or scan specific registries, to scan a more reasonable amount of images.
