iDNA Applications collects design data in order to surface insights and complexity about the various applications in your environment. To determine if there are issues with design collections either

• click on the STATUS area in the top menu bar
  
• or select it from the menu Settings > Design analysis status.

From here, you will receive all messages about why iDNA had a failure collecting design information regarding a particular database. The issues could be wide and varied to actual issues with the application’s design structure (this is a Domino error, not an iDNA one). You get a hint about what is broken and you need to fix the design yourself: This could be permission issues, server down, etc.
