# Home Tab
|
||||
|
||||
The Home tab allows users to see an overview of their Room.
|
||||
|
||||
## Total nodes
|
||||
|
||||
The total number of nodes is presented and dissected by their state, Live, Offline or Stale.
|
||||
|
||||
## Active alerts
|
||||
|
||||
The number of active alerts is presented in a donut chart, while also having counters for both Critical and Warning alerts.
|
||||
|
||||
## Nodes map
|
||||
|
||||
A map consisting of node entries allows for quick hoverable information about each node, while also presenting node status in a color-coded way.
|
||||
|
||||
The map classification can be altered, allowing the categorization of nodes by:
|
||||
|
||||
- Status (e.g. Live)
|
||||
- OS (e.g. Ubuntu)
|
||||
- Technology (e.g. Container)
|
||||
- Agent version (e.g. v1.45.2)
|
||||
- Replication factor (e.g. Single, Multi)
|
||||
- Cloud provider (e.g AWS)
|
||||
- Cloud region (e.g. us-east-1)
|
||||
- Instance type (e.g. c6a.xlarge)
|
||||
|
||||
Color-coding can also be configured between:
|
||||
|
||||
- Status (e.g. Live, Offline)
|
||||
- Connection stability (e.g. Stable, Unstable)
|
||||
- Replication factor (e.g. None, Single)
|
||||
|
||||
## Data replication
|
||||
|
||||
There are two views about data replication in the Home tab:
|
||||
|
||||
The first bar chart presents the amount of **Parents**, **Children** and **Standalone** nodes.
|
||||
|
||||
The second bar chart presents the number of nodes depending on their Replication factor, **None**, **Single** and **Multi**.
|
||||
|
||||
## Alerts overview over the last 24h
|
||||
|
||||
There are two views that display information about nodes that produced the most alerts and top alerts in the last 24 hours.
|
||||
|
||||
The first bar chart presents the nodes that produced the most alerts in a time window of the last 24 hours.
|
||||
|
||||
The second table contains the top alerts in the last 24 hours, along with their instance, the occurrences and their duration in seconds.
|
||||
|
||||
## Netdata Assistant shortcut
|
||||
|
||||
In the Home tab there is a shortcut button in order to start an instant conversation with the [Netdata Assistant](https://github.com/netdata/netdata/edit/master/docs/cloud/netdata-assistant.md).
|
||||
|
||||
## Space metrics
|
||||
|
||||
There are three key metrics that are displayed in the Home tab, **Metrics collected**, **Charts visualized** and **Alerts configured**.
|
||||
|
||||
## Data retention per Nodes
|
||||
|
||||
This bar chart shows the number of nodes based on their retention period.

# See an overview of your infrastructure
|
||||
|
||||
In Netdata Cloud, your nodes are organized into War Rooms. One of the two available views for a War Room is the
|
||||
[**Overview**](https://github.com/netdata/netdata/blob/master/docs/cloud/visualize/overview.md), which uses composite charts to display
|
||||
real-time, aggregated metrics from all the nodes (or a filtered selection) in a given War Room.
|
||||
|
||||
With Overview's composite charts, you can see your infrastructure from a single pane of glass, discover trends or
|
||||
anomalies, then drill down with filtering or single-node dashboards to see more. In the screenshot below,
|
||||
each chart visualizes average or sum metrics values from across 5 distributed nodes.
|
||||
|
||||
Netdata also supports robust Kubernetes monitoring using the Overview. Read our [deployment
|
||||
doc](https://github.com/netdata/netdata/blob/master/packaging/installer/methods/kubernetes.md) for details on visualizing Kubernetes metrics in Netdata Cloud.
|
||||
|
||||
|
||||
|
||||
## Using the Overview
|
||||
|
||||
The Overview uses roughly the same interface as local Agent dashboards or single-node dashboards in Netdata Cloud. By
|
||||
showing all available metrics from all your nodes in a single interface, Netdata Cloud helps you visualize the overall
|
||||
health of your infrastructure. Best of all, you don't have to worry about creating your own dashboards just to get
|
||||
started with infrastructure monitoring.
|
||||
|
||||
Let's walk through some examples of using the Overview to monitor and troubleshoot your infrastructure.
|
||||
|
||||
### Filter nodes and pick relevant times
|
||||
|
||||
While not exclusive to Overview, you can use two important features, [node
|
||||
filtering](https://github.com/netdata/netdata/blob/master/docs/cloud/visualize/node-filter.md) and the [time & date
|
||||
picker](https://github.com/netdata/netdata/blob/master/docs/dashboard/visualization-date-and-time-controls.md), to widen or narrow your infrastructure
|
||||
monitoring focus.
|
||||
|
||||
By default, the Overview shows composite charts aggregated from every node in the War Room, but you can change that
|
||||
behavior on an ad-hoc basis. The node filter allows you to create complex queries against your infrastructure based on
|
||||
the name, OS, or services running on nodes. For example, use `(name contains aws AND os contains ubuntu) OR services ==
|
||||
apache` to show only nodes that have `aws` in the hostname and are Ubuntu-based, or any nodes that have an Apache
|
||||
webserver running on them.
|
||||
|
||||
The time & date picker helps you visualize both small and large timeframes depending on your goals, whether that's
|
||||
establishing a baseline of infrastructure performance or targeted root cause analysis of a specific anomaly.
|
||||
|
||||
For example, use the **Quick Selector** options to pick the 12-hour option first thing in the morning to check your
|
||||
infrastructure for any odd behavior overnight. Use the 7-day option to observe trends between various days of the week.
|
||||
|
||||
See the [War Rooms](https://github.com/netdata/netdata/blob/master/docs/cloud/manage/organize-your-infrastrucutre-invite-your-team.md#netdata-cloud-war-rooms) docs for more details on both features.
|
||||
|
||||
### Configure composite charts to identify problems
|
||||
|
||||
Let's say you notice a sharp decrease in available RAM for applications, as seen in the example screenshot below. In
|
||||
this situation, you can see when the anomalous behavior began and that it affects the average available and committed
|
||||
RAM across your infrastructure. However, when _grouped by dimension_, composite charts cannot show whether an anomaly
|
||||
affects a single node, a subset of nodes, or an entire infrastructure.
|
||||
|
||||
|
||||
|
||||
Use [_group by node_](https://github.com/netdata/netdata/blob/master/docs/cloud/visualize/overview.md#group-by-dimension-or-node) to visualize
|
||||
a single metric across all contributing nodes. If the composite chart has 5 contributing nodes, there will be 5
|
||||
lines/areas, one for the most relevant dimension from each node.
|
||||
|
||||
|
||||
|
||||
After grouping by node, it's clear that the `Composite-Charts-01` node is experiencing anomalous behavior and should be
|
||||
investigated further by jumping to its [single-node dashboard](#drill-down-with-single-node-dashboards) in Netdata
|
||||
Cloud.
|
||||
|
||||
### Drill down with single-node dashboards
|
||||
|
||||
Click on **X Charts** of any composite chart's definition bar to display a dropdown of contributing contexts and nodes
|
||||
contributing. Click on the link icon <img class="img__inline img__inline--link"
|
||||

|
||||
given node to quickly _jump to the same chart in that node's single-node dashboard_ in Netdata Cloud.
|
||||

||||
You can use single-node dashboards in Netdata Cloud to drill down on specific issues, scrub backward in time to
|
||||
investigate historical data, and see like metrics presented meaningfully to help you troubleshoot performance problems.

||||

||||

|
||||
|
||||
## Nodes tab
|
||||
|
||||
You can also use the **Nodes tab** to monitor the health status and user-configurable key metrics from multiple nodes
|
||||
in a War Room. Read the [Nodes tab documentation](https://github.com/netdata/netdata/blob/master/docs/cloud/visualize/nodes.md) for details.
