# Diff View - Comparing Diagrams You can now use Hava to easily identify what has changed in your cloud environments. Hava monitors connected cloud accounts in the background and updates diagram versions as changes are detected. This is done automatically, no manual intervention or log in is required to update diagrams. When a change is detected, a new diagram is generated and the superseded diagram is retained in versioning. {% embed url="" %} Hava Diagram Versions {% endembed %} The Hava version comparison feature or "Diff View" allows you to select 2 diagrams and using the compare revisions function you can immediately see what changes have been made. Simply select the first diagram version you wish to compare (Diagram A) and then select 'Compare revisions' Then from the versions list select the diagram from a point in time you wish to compare diagram A to. This second selection is Diagram B.
The diagram you are viewing will temporarily grey out all the resource icons, following that any changed resources will appear on the diagram as either: * Red - The resource was removed * Green - The resource was added This allows you to easily see all the resource changes in seconds. Diagram A can be any diagram version in the list. As can Diagram B - compare forwards or backwards in time. Here is a short walkthrough showing the Diff View in action. {% embed url="" %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
