Cluster

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 select Cluster.

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.
CPU reservation	The amount of CPU that has been reserved in the cluster.
CPU used	The amount of CPU used by the cluster. This is only visible if you have enabled using the metrics API.
Leader status	This section lists components and their leader node in your cluster.

Nodes

This section lists the nodes in your cluster with information about each node. To view details of a specific node, click the name of the node in the list.

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

Node stats are only available when you have enabled using the metrics API.

If you need to adjust elements of your Kubernetes configuration you can do so here as well.
