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](/web/gui/README.md#time--date-picker) and [Netdata +Cloud](https://learn.netdata.cloud/docs/cloud/war-rooms#time--date-picker) 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.io`, `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](/web/README.md#charts-contexts-families) 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. + +| Change | Method #1 | Method #2 | Method #3 | +| ------------------------------------------------- | ----------------------------------- | --------------------------------------------------------- | ---------------------------------------------------------- | +| **Stop** a chart from updating | `click` | | | +| **Reset** charts to default auto-refreshing state | `double click` | `double tap` (touchpad/touchscreen) | | +| **Select** a certain timeframe | `ALT` + `mouse selection` | `⌘` + `mouse selection` (macOS) | | +| **Pan** forward or back in time | `click and drag` | `touch and drag` (touchpad/touchscreen) | | +| **Zoom** to a specific timeframe | `SHIFT` + `mouse selection` | | | +| **Zoom** in/out | `SHIFT`/`ALT` + `mouse scrollwheel` | `SHIFT`/`ALT` + `two-finger pinch` (touchpad/touchscreen) | `SHIFT`/`ALT` + `two-finger scroll` (touchpad/touchscreen) | + + + +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](https://learn.netdata.cloud/docs/cloud/visualize/overview) doc. + +## What's next? + +Netdata Cloud users can [build new dashboards](/docs/visualize/create-dashboards.md) 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](/docs/monitor/configure-alarms.md) alarms, and [send notifications](/docs/monitor/enable-notifications.md) +to get informed when something goes wrong in your infrastructure. + +### Related reference documentation + +- [Netdata Agent · Web dashboards overview](/web/README.md) +- [Netdata Cloud · War Rooms](https://learn.netdata.cloud/docs/cloud/war-rooms) +- [Netdata Cloud · Overview](https://learn.netdata.cloud/docs/cloud/visualize/overview) +- [Netdata Cloud · Nodes](https://learn.netdata.cloud/docs/cloud/visualize/nodes) +- [Netdata Cloud · Build new dashboards](https://learn.netdata.cloud/docs/cloud/visualize/dashboards) + +[](<>) diff --git a/docs/visualize/overview-infrastructure.md b/docs/visualize/overview-infrastructure.md new file mode 100644 index 00000000..675abd74 --- /dev/null +++ b/docs/visualize/overview-infrastructure.md @@ -0,0 +1,109 @@ +<!-- +title: "See an overview of your infrastructure" +description: "With Netdata Cloud's War Rooms, you can see real-time metrics, from any number of nodes in your infrastructure, in composite charts." +custom_edit_url: https://github.com/netdata/netdata/edit/master/docs/visualize/overview-infrastructure.md +--> + +# 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**, 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. + + + +## Using the Overview + +> ⚠️ In order for nodes to contribute to composite charts, and thus the Overview UI, they must run v1.26.0 or later of +> the Netdata Agent. See our [update docs](/packaging/installer/UPDATE.md) for the preferred update method based on how +> you installed the Agent. + +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://learn.netdata.cloud/docs/cloud/war-rooms#node-filter) and the [time & date +picker](https://learn.netdata.cloud/docs/cloud/war-rooms#time--date-picker), 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://learn.netdata.cloud/docs/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://learn.netdata.cloud/docs/cloud/visualize/overview#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.
