Schema and Description
Schema
- app: application id (encrypted)
- func: function id (encrypted), and unique only within an application
- end_timestamp: function invocation end timestamp (in seconds)
- duration: duration of function invocation (in seconds)
Remarks
In Azure Functions, the unit of deployment is called an application, and an application has one or more functions. For example, an application could be a binary file with one or more entry points. A function invocation specifies both the app id and the func id withen the app.
Invocation timestamps have been modified from those in the actual production trace.
