Minitrace-Go
A high-performance, ergonomic timeline tracing library for Golang.
Basic Usage
package main
import (
"context"
"fmt"
"strconv"
"github.com/tikv/minitrace-go"
)
func tracedFunc(ctx context.Context, event string) {
span := minitrace.StartSpan(ctx, event)
// code snippet...
span.Finish()
}
func iterTracedFunc(ctx context.Context) {
// extend tracing context from parent context
ctx, span := minitrace.StartSpanWithContext(ctx, "1")
span.AddProperty("k2", "v2")
for i := 2; i < 10; i++ {
tracedFunc(ctx, strconv.Itoa(i))
}
span.Finish()
}
func main() {
ctx := context.Background()
// enable tracing
ctx, root := minitrace.StartRootSpan(ctx, "root", 0, nil)
root.AddProperty("k1", "v1")
// pass the context to traced functions
iterTracedFunc(ctx)
// collect tracing results into `spans`
spans, _ := root.Collect()
// do something with `spans`
fmt.Printf("%+v", spans)
}
