⚠️ This new version of charts is currently only available on Netdata Cloud. We didn't want to keep this valuable feature from you, so after we get this into your hands on the Cloud, we will collect and implement your feedback to make sure we are providing the best possible version of the feature on the Netdata Agent dashboard as quickly as possible.
Netdata excels in collecting, storing, and organizing metrics in out-of-the-box dashboards. To transform all this data into a visualization tool effective in making sense out of all the available metrics, we offer an enhanced version of Netdata charts. These charts provide a lot of useful information, and allow you to further explore your data.
Built on top of charts, that update every second with new metrics, we aimed to bring the following to you:
- Enjoy the high-resolution, granular metrics collected by Netdata
- Explore visualization with more options such as line, stacked and area types (other types like bar, pie and gauges are to be added shortly)
- Examine all the metrics where your cursor is with a tooltip
- Use intuitive tooling and shortcuts to pan, zoom or highlight your charts
- On highlight, ease access to Metric Correlations so you can see which other metrics have similar patterns
- Have the dimensions sorted based on name or value
- Full screen mode
- Useful information about the chart, its plugin, context, and type
- Get the chart status and possible errors. On top, reload functionality
Here, you can see the overall look and feel of the new charts for both with a composite chart from the Overview tab and a simple chart from the Single:
With a quick glance you have immediate information available at your disposal:
- Chart title and units
- Action bars
- Chart area
- Legend with dimensions
Your charts are controlled using the available Time controls. Besides these, when interacting with the chart you can also activate these controls by:
hovering over any chart to temporarily pause it - this momentarily switches time control to Pause, so that you can hover over a specific timeframe. When moving out of the chart time control will go back to Play (if it was it's previous state)
clicking on the chart to lock it - this enables the Pause option on the time controls, to the current timeframe. This is if you want to jump to a different chart to look for possible correlations.
double clicking to release a previously locked chart - move the time control back to Play
|Pause a chart||Temporarily Pause|
|Stop a chart||Pause|
|Reset a chart||Play|
When you start interacting with a chart, you'll notice valuable information on the top bar. You will see information from the chart title to a chart action bar.
The elements that you can find on this top bar are:
- Netdata icon: this indicates that data is continuously being updated, this happens if Time controls are in Play or Force Play mode
- Chart status icon: indicates the status of the chart. Possible values are: Loading, Timeout, Error or No data
- Chart title: on the chart title you can see the title together with the metric being displayed, as well as the unit of measurement
- Chart action bar: here you'll have access to chart info, change chart types, enables fullscreen mode, and the ability to add the chart to a custom dashboard
On this bar you have access to immediate actions over the chart, the available actions are:
- Chart info: you will be able to get more information relevant to the chart you are interacting with
- Chart type: change the chart type from line, stacked or area
- Enter fullscreen mode: allows you expand the current chart to the fullsize of your screen
- Add chart to dashboard: This allows you to add the chart to an existing custom dashboard or directly create a new one that includes the chart.
When exploring the chart you will see a second action bar. This action bar is there to support you on this task. The available actions that you can see are:
- Horizontal and Vertical zooms
- In-context zoom in and out
Drag your mouse/finger to the right to pan backward through time, or drag to the left to pan forward in time. Think of it like pushing the current timeframe off the screen to see what came before or after.
Selecting timeframes is useful when you see an interesting spike or change in a chart and want to investigate further, from looking at the same period of time on other charts/sections or triggering actions to help you troubleshoot with an in-context action bar to help you troubleshoot (currently only available on Single Node view). The available actions:
- run Metric Correlations
- zoom in on the selected timeframe
Metric Correlations will only be available if you respect the timeframe selection limitations. The selected duration pill together with the button state helps visualize this.
|Highlight a specific timeframe|
Zooming in helps you see metrics with maximum granularity, which is useful when you're trying to diagnose the root cause of an anomaly or outage. Zooming out lets you see metrics within the larger context, such as the last hour, day, or week, which is useful in understanding what "normal" looks like, or to identify long-term trends, like a slow creep in memory usage.
The actions above are normal vertical zoom actions. We also provide an horizontal zoom action that helps you focus on a specific Y-axis area to further investigate a spike or dive on your charts.
|Zoom in or out|
|Zoom to a specific timeframe|
|Horizontal Zoom a specific Y-axis area|
You also have two direct action buttons on the exploration action bar for in-context
Zoom in and
The bottom legend of the chart where you can see the dimensions of the chart can now be ordered by:
- Dimension name (Ascending or Descending)
- Dimension value (Ascending or Descending)
Hiding dimensions simplifies the chart and can help you better discover exactly which aspect of your system might be behaving strangely.
|Show one dimension and hide others|
|Toggle (show/hide) one dimension|
To resize the chart, click-and-drag the icon on the bottom-right corner of any chart. To restore the chart to its original height, double-click the same icon.
We recommend you read up on the differences between chart dimensions, contexts, and families to strengthen your understanding of how Netdata organizes its dashboards. Another valuable way to interact with charts is to use the date and time controls, which helps you visualize specific moments of historical metrics.
