Instana instrumentation for Microsoft Azure Functions

This module contains the instrumentation code for Microsoft Azure functions written in Go that uses the custom runtime.

Installation

To add github.com/instana/go-sensor/instrumentation/instaazurefunction to your go.mod file, from your project directory run:

$ go get github.com/instana/go-sensor/instrumentation/instaazurefunction

Usage

Instrumenting a custom handler

To instrument a custom handler, wrap it with instaazurefunction.WrapFunctionHandler() before passing it to the http router.

func handlerFn(w http.ResponseWriter, r *http.Request) {
	// ...
}

func main() {
// Initialize a new collector.
collector := instana.InitCollector(&instana.Options{
	Service: "my-azf-collector",
})

// Instrument your handler before passing it to the http router.
http.HandleFunc("/api/azf-test", instaazurefunction.WrapFunctionHandler(collector, handlerFn))
}

Refer the instaazurefunction package documentation for more details.

Limitations

• The instrumentation supports only HTTP and Queue trigger types.
• The instrumentation cannot support HTTP triggers if enableForwardingHttpRequest is set to true in the host.json file.
