Manual Go Tracing
Learn how to set up highlight.io tracing for your Go application.
1
Install the Highlight Go SDK.
Install the highlight-go
package with go get
.
go get -u github.com/highlight/highlight/sdk/highlight-go
2
Initialize the Highlight Go SDK.
highlight.Start
starts a goroutine for recording and sending backend traces and errors. Setting your project id lets Highlight record errors for background tasks and processes that aren't associated with a frontend session.
import (
"github.com/highlight/highlight/sdk/highlight-go"
)
func main() {
// ...
highlight.SetProjectID("<YOUR_PROJECT_ID>")
highlight.Start(
highlight.WithServiceName("my-app"),
highlight.WithServiceVersion("git-sha"),
)
defer highlight.Stop()
// ...
}
3
Wrap your code using the Go SDK.
By wrapping your code with StartTrace
and EndTrace
, the Highlight Go SDK will record a span. You can create more child spans using the child context or add custom attributes to each span.
import (
"github.com/highlight/highlight/sdk/highlight-go"
"go.opentelemetry.io/otel/attribute"
)
func functionToTrace(ctx context.Context, input int) {
s, childContext := highlight.StartTrace(ctx, "functionToTrace", attribute.Int("custom_property", input))
// ...
anotherFunction(childContext)
// ...
highlight.EndTrace(s)
}
func anotherFunction(ctx context.Context) {
s, _ := highlight.StartTrace(ctx, "anotherFunction")
// ...
highlight.EndTrace(s)
}

Verify your backend traces are being recorded.
Visit the highlight traces portal and check that backend traces are coming in.
