# Connecting to applications: kubectl port-forward
kubectl port-forward forwards connections to a local port to a port on a pod. Its man page is available [here](kubectl/kubectl_port-forward.html). Compared to [kubectl proxy](accessing-the-cluster.html#using-kubectl-proxy), `kubectl port-forward` is more generic as it can forward TCP traffic while `kubectl proxy` can only forward HTTP traffic. This guide demonstrates how to use `kubectl port-forward` to connect to a Redis database, which may be useful for database debugging.

# Resource Usage Monitoring in Kubernetes
Understanding how an application behaves when deployed is crucial to scaling the application and providing a reliable service. In a Kubernetes cluster, application performance can be examined at many different levels: containers, [pods](pods.html), [services](services.html), and whole clusters. As part of Kubernetes we want to provide users with detailed resource usage information about their running applications at all these levels. This will give users deep insights into how their applications are performing and where possible application bottlenecks may be found. In comes [Heapster](https://github.com/GoogleCloudPlatform/heapster), a project meant to provide a base monitoring platform on Kubernetes.
