# Details

A cluster is a collection of nodes that runs containerized workloads. Portainer lets you keep track of your cluster and its individual nodes, including resource usage and configuration.

From the menu expand the **Cluster** section and select **Details**.

The following information is provided:

| Attribute          | Overview                                                                                                                                                                                 |
| ------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Memory reservation | The amount of memory available to the cluster.                                                                                                                                           |
| Memory used        | The amount of memory used by the cluster. This is only visible if you have [enabled using the metrics API](/sts/user/kubernetes/cluster/setup.md#enable-features-using-the-metrics-api). |
| CPU reservation    | The amount of CPU that has been reserved in the cluster.                                                                                                                                 |

## Omni cluster management

{% hint style="info" %}
This section only appears when the environment is a [Talos Kubernetes cluster provisioned by Portainer through Omni](/sts/admin/environments/add/kube-create/omni.md).
{% endhint %}

In this section you can see and update the versions of Kubernetes and Talos on your Talos Kubernetes cluster provisioned by Portainer.

{% hint style="warning" %}
This functionality is in beta and only tested with some configurations.
{% endhint %}

## Nodes

This section lists the nodes in your cluster with information about each node. To view [details of a specific node](/sts/user/kubernetes/cluster/details/node.md), click the name of the node in the list.

<figure><img src="/files/k0MF6nCUGFhU7eFitawN" alt=""><figcaption></figcaption></figure>

The **Conditions** column shows any conditions that are currently active on the node. If no conditions are displayed, this indicates the node is healthy. Any active conditions (DiskPressure, MemoryPressure, PIDPressure, NetworkUnavailable) will be displayed for the particular node.

The **Cached images** column shows the number of cached images on each node. Click the displayed number to view a list of those images, including details of the image size and alias count.

To view usage stats for a node, click the stats icon to the right of the node.

{% hint style="info" %}
Node stats are only available when you have [enabled using the metrics API](/sts/user/kubernetes/cluster/setup.md#enable-features-using-the-metrics-api).
{% endhint %}

On Talos Kubernetes or MicroK8s environments provisioned with the [Create a Kubernetes cluster](/sts/admin/environments/add/kube-create.md) feature, you will also see buttons to add and remove nodes as well as additional action icons on MicroK8s environments to view the MicroK8s status (for control plane nodes) and to connect to the environment via SSH console.

If you need to adjust elements of your Kubernetes configuration you can do so by selecting **Setup** in the left menu.

{% content-ref url="/pages/-MjRM\_OFtkA1vnKQKuzp" %}
[Setup](/sts/user/kubernetes/cluster/setup.md)
{% endcontent-ref %}

If you would like to define security constraints on the pods in your environment, select **Security constraints**.

{% content-ref url="/pages/MgJUuNB8QGTUai2EdTHh" %}
[Security constraints](/sts/user/kubernetes/cluster/security.md)
{% endcontent-ref %}
