== Stop Daemon

It can be helpful to stop the Daemon when troubleshooting or debugging a failure.

Daemons automatically stop given any of the following conditions:

* Available system memory is low
* Daemon has been idle for 3 hours

To stop running Daemon processes, use the following command:

----
$ gradle --stop
----

			kubeConfigSha := sha256.Sum256(kubeConfig)
			if bytes.Equal(kubeConfigSha[:], prev.kubeConfigSha[:]) {
				logger.Infof("skipping update (kubeconfig are identical)")
				continue
			}
			// stop previous remote cluster
			prev.Stop()
		} else if c.cs.Contains(cluster.ID(clusterID)) {
			// if the cluster has been registered before by another secret, ignore the new one.
			logger.Warnf("cluster has already been registered")

a global LevelVar:

	var programLevel = new(slog.LevelVar) // Info by default

Then use the LevelVar to construct a handler, and make it the default:

	h := slog.NewJSONHandler(os.Stderr, &slog.HandlerOptions{Level: programLevel})
	slog.SetDefault(slog.New(h))

Now the program can change its logging level with a single statement:

	programLevel.Set(slog.LevelDebug)
