-		The metrics shown are specifically optimized for Kubernetes autoscaling
+		This command requires Metrics Server to be correctly configured and working on the server. `))
-		decisions, such as those made by the Horizontal Pod Autoscaler (HPA) and
-		Vertical Pod Autoscaler (VPA). Because of this, the values may not match those
-		from standard OS tools like 'top', as the metrics are designed to provide a
-		stable signal for autoscalers rather than for pinpoint accuracy.
-
-		When to use this command:
-
-		* For on-the-fly spot-checks of resource usage (e.g. identify which pods
-		  are consuming the most resources at a glance, or get a quick sense of the load
-		  on your nodes)
-		* Understand current resource consumption patterns
-		* Validate the behavior of your HPA or VPA configurations by seeing the metrics
-		  they use for scaling decisions.
-
-		It is not intended to be a replacement for full-featured monitoring solutions.
-		Its primary design goal is to provide a low-overhead signal for autoscalers,
-		not to be a perfectly accurate monitoring tool. For high-accuracy reporting,
-		historical analysis, dashboarding, or alerting, you should use a dedicated
-		monitoring solution.`))
