State Checker is an ACI app that will allow you to snapshot a subset of objects in the fabric and compare them. This will allow you to answer questions like
- What changed in my fabric between windows
- Are my critical objects the same after maintenance
- Are all my routes/endpoints still present
StateChecker is available on the appstore (insert-link-here) and can be deployed on in standalone mode with the ability to connect ACI fabrics. Further details can be found on readthedocs
