GymLog
This is a gym exercise log application using Power Apps, Azure Functions, Table Storage, Service Bus and Cosmos DB.
As long as the Azure Functions app knows the instrumentation key from an Application Insights instance, it traces almost everything. OpenTelemetry.NET is one of the Open Telemetry implementations, has recently released v1.0 for tracing. Both metrics and logging are close to GA. However, it doesn't work well with Azure Functions. Therefore, in this post, let's manually implement the tracing at the log level, which is sent to Application Insights.

Here's the extension method for the ILogger interface. Let's have a look at the sample code below that checks in the request data from Power Apps is successfully captured on the routine action. Both correlationId and spanId are sent from Power Apps (line #9-10). The invocationId fro the Azure Functions context has become the eventId (line #12). Finally, event type, event status, span type, span status, interface type and correlation ID are logged (line #14-17).
