+# Home, overview and single node tabs
+
+Learn how to use the Home, Overview, and Single Node tabs in Netdata Cloud, to explore your infrastructure and troubleshoot issues.
+
+## Home
+
+The Home tab provides a predefined dashboard of relevant information about entities in the War Room.
+
+This tab will automatically present summarized information in an easily digestible display. You can see information about your
+nodes, data collection and retention stats, alerts, users and dashboards.
+
+## Overview and single node tab
+
+The Overview tab is another great way to monitor infrastructure using Netdata Cloud. While the interface might look
+similar to local dashboards served by an Agent Overview uses **composite charts**.
+These charts display real-time aggregated metrics from all the nodes (or a filtered selection) in a given War Room.
+
+When you [interact with composite charts](https://github.com/netdata/netdata/blob/master/docs/cloud/visualize/interact-new-charts.md)
+you can see your infrastructure from a single pane of glass, discover trends or anomalies, and perform root cause analysis.
+
+The Single Node tab dashboard is exactly the same as the Overview, but with a hard-coded filter to only show a single node.
+
+### Chart navigation Menu
+
+Netdata Cloud uses a similar menu to local Agent dashboards, with sections
+and sub-menus aggregated from every contributing node. For example, even if only two nodes actively collect from and
+monitor an Apache web server, the **Apache** section still appears and displays composite charts from those two nodes.
+

+
+One difference between the Netdata Cloud menu and those found in local Agent dashboards is that
+the Overview condenses multiple services, families, or instances into single sections, sub-menus, and associated charts.
+
+For services, let's say you have two concurrent jobs with the [web_log collector](https://github.com/netdata/go.d.plugin/blob/master/modules/weblog/README.md), one for Apache and another for Nginx.
+A single-node or local dashboard shows two section, **web_log apache** and **web_log nginx**, whereas the Overview condenses these into a
+single **web_log** section containing composite charts from both jobs.
+
+The Cloud also condenses multiple families or multiple instances into a single **all** sub-menu and associated charts.
+For example, if Node A has 5 disks, and Node B has 3, each disk contributes to a single `disk.io` composite chart.
+The utility bar should show that there are 8 charts from 2 nodes contributing to that chart.
+The aggregation applies to disks, network devices, and other metric types that involve multiple instances of a piece of hardware or software.
+
+## Persistence of composite chart settings
+
+Of course you can [change the filtering or grouping](https://github.com/netdata/netdata/blob/master/docs/cloud/visualize/interact-new-charts.md) of metrics in the composite charts that aggregate all these instances, to see only the information you are interested in, and save that tab in a custom dashboard.
+
+When you change a composite chart via its definition bar, Netdata Cloud persists these settings in a query string attached to the URL in your browser.
+You can "save" these settings by bookmarking this particular URL, or share it with colleagues by having them copy-paste it into their browser.
