-# Nodes tab

-The Nodes tab lets you see and customize key metrics from any number of Agent-monitored nodes and seamlessly navigate
-to any node's dashboard for troubleshooting performance issues or anomalies using Netdata's highly-granular metrics.

-
-Each War Room's Nodes tab is populated based on the nodes you added to that specific War Room. Each node occupies a
-single row, first featuring that node's alert status (yellow for warnings, red for critical alerts) and operating
-system, some essential information about the node, followed by columns of user-defined key metrics represented in
-real-time charts.
-
-Use the [Overview](https://github.com/netdata/netdata/blob/master/docs/cloud/visualize/overview.md) for monitoring an infrastructure in real time using
-composite charts and Netdata's familiar dashboard UI.
-
-Check the [node
-filter](https://github.com/netdata/netdata/blob/master/docs/cloud/visualize/node-filter.md) and the [Visualization date time controls
-selector](https://github.com/netdata/netdata/blob/master/docs/dashboard/visualization-date-and-time-controls.md) for tools available on the utility bar.
-
-## Add and customize metrics columns
-
-Add more metrics columns by clicking the gear icon. Choose the context you'd like to add, give it a relevant name, and
-select whether you want to see all dimensions (the default), or only the specific dimensions your team is interested in.
-
-Click the gear icon and hover over any existing charts, then click the pencil icon. This opens a panel to
-edit that chart. Edit the context, its title, add or remove dimensions, or delete the chart altogether.
-
-These customizations appear for anyone else with access to that War Room.
-
-## See more metrics in Netdata Cloud
-
-If you want to add more metrics to your War Rooms and they don't show up when you add new metrics to Nodes, you likely
-need to configure those nodes to collect from additional data sources. See our [collectors configuration reference](https://github.com/netdata/netdata/blob/master/src/collectors/REFERENCE.md) 
-to learn how to use dozens of pre-installed collectors that can instantly collect from your favorite services and applications.
-
-If you want to see up to 30 days of historical metrics in Cloud (and more on individual node dashboards), read about [changing how long Netdata stores metrics](https://github.com/netdata/netdata/blob/master/docs/store/change-metrics-storage.md). Also, see our
-[calculator](https://github.com/netdata/netdata/blob/master/docs/store/change-metrics-storage.md#calculate-the-system-resources-ram-disk-space-needed-to-store-metrics)
-for finding the disk and RAM you need to store metrics for a certain period of time.

+# Nodes tab
+
+The nodes tab provides a summarized view of your [War Room](https://github.com/netdata/netdata/blob/master/docs/cloud/manage/organize-your-infrastrucutre-invite-your-team.md#netdata-cloud-war-rooms), allowing you to view quick information per node.
+
+> **Tip**  
+>
+> Keep in mind that all configurations mentioned below are persistent and visible across all users.
+
+## Center information view
+
+The center information view consists of one row per node, and can be configured and filtered by the user.
+
+### Filtering and adjusting the view
+
+In the top right-hand corner, you can:
+
+- Order the nodes per status or per alert status
+- Select which charts you want to be displayed as quick reference points
+
+### Node row
+
+Each node row allows you to:
+
+- View the node's status
+- Go to a single node dashboard, by clicking the node name
+- View information about the node, along with a button to display more in the right-hand sidebar
+- View active alerts for the node
+- View Machine Learning status
+- View Functions capability status
+- Add configuration (beta)
+- [Add alert silencing rules](https://github.com/netdata/netdata/blob/master/docs/cloud/alerts-notifications/manage-alert-notification-silencing-rules.md)
+- View a set of key attributes collected on your node
+
+## Right bar
+
+The bar on the right-hand side provides additional information about the nodes in the War Room and allows you to filter what is displayed in the [center information view](#center-information-view).
+
+### Node hierarchy
+
+The first tab displays a hierarchy of the nodes displayed, making it easy to find a specific node by name. It follows the ordering that the user has selected.
+
+### Filters sub-tab
+
+The second tab allows you to filter which nodes are displayed, you can filter by:
+
+- Host labels
+- Node status
+- Netdata version
+- Individual nodes
+
+### Alerts sub-tab
+
+The third tab displays room alerts and allows you to see additional information about each alert.
+
+### Info sub-tab
+
+The last tab presents information about a node, by clicking the `i` icon from a node's row, right next to its name.
