AHF Print Collections Improvements

AHF now makes it easier to understand any diagnostic collections, which are queued for execution.

When a collection is requested, AHF will review available resources and may queue that collection for execution later when more resources are available.

A new print collections option has been added to show the status of any queued collections:

tfactl print collections -status queued

Diagnostic Collection Improvements

AHF now makes it easier to list the contents of nested diagnostic collections or to list the contents of multiple zip files from the same collection.

• To list the contents of diagnostic collection including any nested zip files, use:

  tfactl collection list-contents -collectionzip zip

• To list the contents of all zip files within a specific collection, use:

  tfactl collection list-contents -collectionname collection-name

Optimization of AHF Compliance Results and Log Storage

Cleanup of AHF compliance results and log data has been improved.

Results and log data management has been available for many releases:

• Automatic retention: COLLECTION_RETENTION=n
• On-demand retention: user_collection_retention=n

AHF now includes a new option -purge_size to specify the retention size to manage results and log data.

For example, to purge compliance data larger than 1024 MB, use:

ahfctl compliance -purge_size 1024
