+  Enable pprof endpoints for Kueue controller manager.
+---
+
+This page shows you how to enable pprof endpoints for Kueue controller manager.
+
+The intended audience for this page are [batch administrators](/docs/tasks#batch-administrator).
+
+## Before you begin
+
+Make sure the following conditions are met:
+
+- A Kubernetes cluster is running.
+- The kubectl command-line tool has communication with your cluster.
+- [Kueue is installed](/docs/installation).
+
+## Enabling pprof endpoints
+
+> _Available in Kueue v0.5.0 and later_
+
+To enable pprof endpoints, you need to set a `pprofBindAddress` is set in the [manager's configuration](/docs/installation/#install-a-custom-configured-released-version).
+
+The easiest way to reach pprof port in kubernetes is to use `port-forward` command.
+
+1. Run the following command to obtain the name of the Pod running Kueue:
+
+```shell
+kubectl get pod -n kueue-system
+NAME                                        READY   STATUS    RESTARTS   AGE
+kueue-controller-manager-769f96b5dc-87sf2   2/2     Running   0          45s
+```
+
+2. Run the following command to initiate the port forwarding to your localhost:
+
+```shell
+kubectl port-forward kueue-controller-manager-769f96b5dc-87sf2 -n kueue-system 8082:8082
+Forwarding from 127.0.0.1:8082 -> 8082
+Forwarding from [::1]:8082 -> 8082
+```
+
+The HTTP endpoint will now be available as a local port.
+
+To learn how to use the exposed endpoint, see [pprof basic usage](https://github.com/google/pprof#basic-usage) and [examples](https://pkg.go.dev/net/http/pprof#hdr-Usage_examples).
