* The kube-apiserver [basic audit log](https://kubernetes.io/docs/admin/audit/) can be enabled in GCE by exporting the environment variable `ENABLE_APISERVER_BASIC_AUDIT=true` before running `cluster/kube-up.sh`. This will log to `/var/log/kube-apiserver-audit.log` and use the same `logrotate` settings as `/var/log/kube-apiserver.log`.

If you use NATS server, check out this sample program below to log the bucket notification added to NATS.

```go
package main

// Import Go and NATS packages
import (
 "log"
 "runtime"

 "github.com/nats-io/nats.go"
)

func main() {

 // Create server connection
 natsConnection, _ := nats.Connect("nats://yourusername:yoursecret@localhost:4222")
 log.Println("Connected")

 // Subscribe to subject

	return ctx, cred, opts, createReq, targetUser, APIError{}
}

// setReqInfoPolicyName will set the given policyName as a tag on the context's request info,
// so that it appears in audit logs.
func setReqInfoPolicyName(ctx context.Context, policyName string) {
	reqInfo := logger.GetReqInfo(ctx)
	reqInfo.SetTags("policyName", policyName)

- Kube-log-runner: Added the `-log-file-size` parameter to rotate log output into a new file once it reached a certain size. Introduced `-log-file-age` to enable automatic removal of old output files, and `-flush-interval` to support periodic flushing.
