Interact with dashboards and charts

You can find Netdata's dashboards in two places: locally served at http://NODE:19999 by the Netdata Agent, and in Netdata Cloud. While you access these dashboards differently, they have similar interfaces, identical charts and metrics, and you interact with both of them the same way.

If you're not sure which option is best for you, see our single-node and infrastructure quickstart guides.

Netdata dashboards are single, scrollable pages with many charts stacked on top of one another. As you scroll up or down, charts appearing in your browser's viewport automatically load and update every second.

The dashboard is broken up into multiple sections, such as System Overview, CPU, Disk, which are automatically generated based on which collectors begin collecting metrics when Netdata starts up. Sections also appear in the right-hand menu, along with submenus based on the contexts and families Netdata creates for your node.

Choose timeframes to visualize#

Both the local Agent dashboard and Netdata Cloud feature time & date pickers to help you visualize specific points in time. In Netdata Cloud, the picker appears in the Overview, Nodes view, new dashboards, and any single-node dashboards you visit.

Netdata Cloud:

Their behavior is identical. Use the Quick Selector to visualize generic timeframes, or use the calendar or inputs to select days, hours, minutes or seconds. Click Apply to re-render all visualizations with new metrics data, or Clear to restore the default timeframe.

See reference documentation for the local Agent dashboard and Netdata Cloud for additional context about how the time & date picker behaves in each environment.

Charts, dimensions, families, and contexts#

A chart is an interactive visualization of one or more collected/calculated metrics. You can see the name (also known as its unique ID) of a chart by looking at the top-left corner of a chart and finding the parenthesized text. On a Linux system, one of the first charts on the dashboard will be the system CPU chart, with the name system.cpu.

A dimension is any value that gets shown on a chart. The value can be raw data or calculated values, such as percentages, aggregates, and more. Most charts will have more than one dimension, in which case it will display each in a different color. You can disable or enable showing these dimensions by clicking on them.

A family is one instance of a monitored hardware or software resource that needs to be monitored and displayed separately from similar instances. For example, if your node has multiple partitions, Netdata will create different families for /, /boot, /home, and so on. Same goes for entire disks, network devices, and more.

A context groups several charts based on the types of metrics being collected and displayed. For example, the Disk section often has many contexts:, disk.ops, disk.backlog, disk.util, and so on. Netdata uses this context to create individual charts and then groups them by family. You can always see the context of any chart by looking at its name or hovering over the chart's date.

See our dashboard docs for more information about the above distinctions and how they're used across Netdata to meaningfully organize and present metrics.

Interact with charts#

Netdata's charts are fully interactive to help you find meaningful information about complex problems. You can pan through historical metrics, zoom in and out, select specific timeframes for further analysis, resize charts, and more. Whenever you use a chart in this way, Netdata synchronizes all the other charts to match it.

These interactions can also be triggered using the icons on the bottom-right corner of every chart. They are, respectively, Pan Left, Reset, Pan Right, Zoom In, and Zoom Out.

You can show and hide individual dimensions by clicking on their names. Use SHIFT + click to hide or show dimensions one at a time. Hiding dimensions simplifies the chart and can help you better discover exactly which aspect of your system is behaving strangely.

You can resize any chart by clicking-and-dragging the icon on the bottom-right corner of any chart. To restore the chart to its original height, double-click the same icon.

Composite charts in Netdata Cloud#

Netdata Cloud now supports composite charts in the Overview interface. Composite charts come with a few additional UI elements and varied interactions, such as the location of dimensions and a utility bar for configuring the state of individual composite charts. All of these details are covered in the Overview reference doc.

What's next?#

Netdata Cloud users can build new dashboards in just a few clicks. By aggregating relevant metrics from any number of nodes onto a single interface, you can respond faster to anomalies, perform more targeted troubleshooting, or keep tabs on a bird's eye view of your infrastructure.

If you're finished with dashboards for now, skip to Netdata's health watchdog for information on creating or configuring alarms, and send notifications to get informed when something goes wrong in your infrastructure.
