}
func New ¶
func New(cfg client.ConfigProvider) *GoMetrics
New creates collector of go metrics. Upon creation enable required metrics by toggling appropriate GoMetrics.Collect* fields.
Example ¶
package main
import (
"context"
"time"
"github.com/aws/aws-sdk-go/aws/session"
"github.com/molecule-man/cwatsch/gometrics"
)
func main() {
ctx, cancel := context.WithCancel(context.Background())
defer cancel()
go func() {
m := gometrics.New(session.Must(session.NewSession()))
m.Namespace = "MyApp"
m.CollectHeapAlloc = true
m.CollectNextGC = true // target heap size of the next GC cycle
m.CollectStackInuse = true // bytes in stack spans.
m.CollectPauseTotalNs = true // cumulative nanoseconds in GC stop-the-world pauses since the program started.
m.CollectNumGC = true // number of completed GC cycles.
m.CollectHeapObjects = true // number of allocated heap objects.
m.CollectNumGoroutine = true
// the metrics will be collected every minute
m.Launch(ctx, time.Minute)
}()
}
