Different sources see different things
Architecture tools explain models and intent. CMDB systems describe configuration records. Cloud and monitoring inventories contribute other observations. Each source can add useful context without claiming to describe every aspect of the estate.
A broader view
Heimdall supports working with these perspectives in a merged landscape. Users can explore connections between source records and inspect the contributing information when a component needs closer attention.
Review coverage alongside content
A source that contributes records is not necessarily complete. Permissions, chosen scope, and source configuration affect visibility. The useful question is both what the source tells you and what it cannot currently establish.
