# Working with Prometheus
For more information on working with [Prometheus metrics](prometheus_metrics.md), see
the documentation.
## Access the UI of a Prometheus managed application in Kubernetes
You can connect directly to Prometheus, and view the Prometheus user interface, when
using a Prometheus managed application in Kubernetes:
1. Find the name of the Prometheus pod in the user interface of your Kubernetes
provider, such as GKE, or by running the following `kubectl` command in your
terminal:
```shell
kubectl get pods -n gitlab-managed-apps | grep 'prometheus-prometheus-server'
```
The command should return a result like the following example, where
`prometheus-prometheus-server-55b4bd64c9-dpc6b` is the name of the Prometheus pod:
```plaintext
gitlab-managed-apps prometheus-prometheus-server-55b4bd64c9-dpc6b 2/2 Running 0 71d
```
1. Run a `kubectl port-forward` command. In the following example, `9090` is the
Prometheus server's listening port:
```shell
kubectl port-forward prometheus-prometheus-server-55b4bd64c9-dpc6b 9090:9090 -n gitlab-managed-apps
```
The `port-forward` command forwards all requests sent to your system's `9090` port
to the `9090` port of the Prometheus pod. If the `9090` port on your system is used
by another application, you can change the port number before the colon to your
desired port. For example, to forward port `8080` of your local system, change the
command to:
```shell
kubectl port-forward prometheus-prometheus-server-55b4bd64c9-dpc6b 8080:9090 -n gitlab-managed-apps
```
1. Open `localhost:9090` in your browser to display the Prometheus user interface.
