Hello all!
There is a 2nd Edition of the "Troubleshooting Cisco Application Centric Infrastructure" which has been mainly available via PDF since the beginning of 2020:
"Troubleshooting Cisco Application Centric Infrastructure, 2nd Edition" PDF
As of recently, the content of this book has been divided and released across multiple external documents and added to the "Cisco Application Policy Infrastructure Controller (APIC)" documentation landing page.
All relevant content can be found under the newly provisioned "TAC-Authored Troubleshooting Guides" > "ACI 2nd Edition Troubleshooting Book" section:
With this new format:
- The content can be consumed piecemeal
- The content can be found through search engines
- The content can be actively updated with feedback
Special thanks to Joseph Young for leading these efforts, and to Jessica Rueda for helping get the content published.
