You can use our REST API to query the audit log, and drill down for specific changes! You will want to query the Events endpoint. For example, if you wanted to find all of the times variables have been modified in the past 90 days, you could use a request like:
Octopus is an “API-first” application, meaning that anything you can do in the web UI, you can do with API calls. We ship Octopus with a SwaggerUI, accessible at
YOUR_OCTOPUS_SERVER/swaggerUI which lists and documents all of the endpoints, as well as allows you to run test calls against your instance.
I hope this helps!
