How can I implement performance logging in Go?
You can use the built-in log
package along with time
to measure execution time of functions.
Can you show me a code example?
Sure! Here's a simple example:
package main
import (
"fmt"
"log"
"time"
)
func logExecutionTime(start time.Time, functionName string) {
elapsed := time.Since(start)
log.Printf("%s took %s", functionName, elapsed)
}
func exampleFunction() {
defer logExecutionTime(time.Now(), "exampleFunction")
// Simulate work
time.Sleep(2 * time.Second)
}
func main() {
exampleFunction()
}
What if I want to log to a file instead of the console?
You can create a log file using os.OpenFile
and set it as the output for the logger. Here's how:
file, err := os.OpenFile("performance.log", os.O_CREATE|os.O_WRONLY|os.O_APPEND, 0666)
if err != nil {
log.Fatal(err)
}
log.SetOutput(file)
