Real-time performance monitoring, done right!

# Netdata

Real-time performance monitoring, in the greatest possible detail

Drag charts to pan. Shift + wheel on them, to zoom in and out. Double-click on them, to reset. Hover on them too!

#### XSS Protection

This dashboard is about to render data from server:

``

To protect your privacy, the dashboard will check all data transferred for cross site scripting (XSS).
This is CPU intensive, so your browser might be a bit slower.

If you trust the remote server, you can disable XSS protection.
In this case, any remote dashboard decoration code (javascript) will also run.

If you don't trust the remote server, you should keep the protection on.
The dashboard will run slower and remote dashboard decoration code will not run, but better be safe than sorry...

#### Print this netdata dashboard

netdata dashboards cannot be captured, since we are lazy loading and hiding all but the visible charts.
To capture the whole page with all the charts rendered, a new browser window will pop-up that will render all the charts at once. The new browser window will maintain the current pan and zoom settings of the charts. So, align the charts before proceeding.

This process will put some CPU and memory pressure on your browser.
For the netdata server, we will sequencially download all the charts, to avoid congesting network and server resources.
Please, do not print netdata dashboards on paper!

#### Preparing dashboard for printing...

Please wait while we initialize and render all the charts on the dashboard.
The print dialog will appear as soon as we finish rendering the page.

#### Import a netdata snapshot

netdata can export and import dashboard snapshots. Any netdata can import the snapshot of any other netdata. The snapshots are not uploaded to a server. They are handled entirely by your web browser, on your computer.

Click here to select the netdata snapshot file to import

Browse for a snapshot file (or drag it and drop it here), then click Import to render it.

#### Export a snapshot

Please wait while we collect all the dashboard data...
Select the desired resolution of the snapshot. This is the seconds of data per point.
Filename
Comments
Select snaphost resolution. This controls the size the snapshot file.

The generated snapshot will include all charts of this dashboard, for the visible timeframe, so align, pan and zoom the charts as needed. The scroll position of the dashboard will also be saved. The snapshot will be downloaded as a file, to your computer, that can be imported back into any netdata dashboard (no need to import it back on this server).

Snapshot files include all the information of the dashboard, including the URL of the origin server, its netdata unique ID, etc. So, if you share the snapshot file with third parties, they will be able to access the origin server, if this server is exposed on the internet.
Snapshots are handled entirely by the web browser. The netdata servers are not aware of them.

#### Welcome to the world of netdata

if there is a metric for something, we want it visualised
and we want this visualisation to be real-time, efficient and awesome
netdata is a new way to monitor your systems and applications, to get real-time insights of what is really happening and what affects performance. It is carefully optimised to be a real-time system, without interfering in any way, to the core function of your systems.
netdata has been designed to monitor massive amounts of metrics, per server, per second. When installed, it might come up with 1k to 3k metrics, but we have been testing it with 100k metrics, all collected per second, and still the cpu utilisation remained negligible.
We have also tried to give each metric, a meaning, a context. We have grouped and categorized all metrics into meaningful charts, providing a better understanding of the underlying technologies and mechanisms.
netdata is free, open-source software. If you decide to use it, it is important to give netdata a star at GitHub.
Enjoy real-time performance monitoring!

#### Dashboard Help

#### Dygraphs (line, area and stacked area charts)

#### Mouse Over / Hover

Mouse over on a chart to show, at its legend, the values for the timestamp under the mouse (the chart will also highlight the point at the chart).
All the other visible charts will also show and highlight their values for the same timestamp.

#### Drag Chart Contents

Drag the contents of a chart, by pressing the left mouse button and moving the mouse, to pan it horizontally.
All the charts will follow soon after you let the chart alone (this little delay is by design: it speeds up your browser and lets you focus on what you are exploring).
Once a chart is panned, auto refreshing stops for all charts. To enable it again, double click a panned chart.

#### Double Click

Double Click a chart to reset all the charts to their default auto-refreshing state.

#### SHIFT + Drag

While pressing the `SHIFT` key, press the left mouse button on the contents of a chart and move the mouse to select an area, to zoom in. The other charts will follow too. Zooming is performed in two phases:

- The already loaded chart contents are zoomed (low resolution)
- New data are transferred from the netdata server, to refresh the chart with possibly more detail.

Once a chart is zoomed, auto refreshing stops for all charts. To enable it again, double click a zoomed chart.

#### Highlight Timeframe

While pressing the `ALT` key, press the left mouse button on the contents of a chart and move the mouse to select an area. The selected are will be highlighted on all charts.

#### SHIFT + Mouse Wheel

While pressing the `SHIFT` key and the mouse pointer is over the contents of a chart, scroll the mouse wheel to zoom in or out. This kind of zooming is aligned to center below the mouse pointer. The other charts will follow too.
Once a chart is zoomed, auto refreshing stops for all charts. To enable it again, double click a zoomed chart.

#### Legend Operations

Click on the label or value of a dimension, will select / un-select this dimension.
You can press any of the SHIFT or CONTROL keys and then click on legend labels or values, to select / un-select multiple dimensions.

#### Single Tap

Single Tap on the contents of a chart to show, at its legend, the values for the timestamp tapped (the chart will also highlight the point at the chart).
All the other visible charts will also show and highlight their values for the same timestamp.

#### Drag Chart Contents

Touch and Drag the contents of a chart to pan it horizontally.
All the charts will follow soon after you let the chart alone (this little delay is by design: it speeds up your browser and lets you focus on what you are exploring).
Once a chart is panned, auto refreshing stops for all charts. To enable it again, double tap a panned chart.

#### Double Tap

Double tap a chart to reset all the charts to their default auto-refreshing state.

#### Zoom (does not work on firefox and IE/Edge)

With two fingers, zoom in or out.
Once a chart is zoomed, auto refreshing stops for all charts. To enable it again, double click a zoomed chart.

#### Legend Operations

Tap on the label or value of a dimension, will select / un-select this dimension.

#### netdata dashboard options

These are browser settings. Each viewer has its own. They do not affect the operation of your netdata server.
Settings take effect immediately and are saved permanently to browser local storage (except the refresh on focus / always option).
To reset all options (including charts sizes) to their defaults, click here.

When to refresh the charts?
When set to On Focus, the charts will stop being updated if the page / tab does not have the focus of the user. When set to Always, the charts will always be refreshed. Set it to On Focus it to lower the CPU requirements of the browser (and extend the battery of laptops and tablets) when this page does not have your focus. Set to Always to work on another window (i.e. change the settings of something) and have the charts auto-refresh in this window.

Which dimensions to show?
When set to Non Zero, dimensions that have all their values (within the current view) set to zero will not be transferred from the netdata server (except if all dimensions of the chart are zero, in which case this setting does nothing - all dimensions are transferred and shown). When set to All, all dimensions will always be shown. Set it to Non Zero to lower the data transferred between netdata and your browser, lower the CPU requirements of your browser (fewer lines to draw) and increase the focus on the legends (fewer entries at the legends).

How to handle hidden charts?
When set to Destroy, charts that are not in the current viewport of the browser (are above, or below the visible area of the page), will be destroyed and re-created if and when they become visible again. When set to Hide, the not-visible charts will be just hidden, to simplify the DOM and speed up your browser. Set it to Destroy, to lower the memory requirements of your browser. Set it to Hide for faster restoration of charts on page scrolling.

| Page scroll handling? When set to Sync, charts will be examined for their visibility immediately after scrolling. On slow computers this may impact the smoothness of page scrolling. To update the page when scrolling ends, set it to Async. Set it to Sync for immediate chart updates when scrolling. Set it to Async for smoother page scrolling on slower computers.

| Which chart refresh policy to use? When set to parallel, visible charts are refreshed in parallel (all queries are sent to netdata server in parallel) and are rendered asynchronously. When set to sequential charts are refreshed one after another. Set it to parallel if your browser can cope with it (most modern browsers do), set it to sequential if you work on an older/slower computer.

Shall we re-sync chart refreshes?
When set to Resync, the dashboard will attempt to re-synchronize all the charts so that they are refreshed concurrently. When set to Best Effort, each chart may be refreshed with a little time difference to the others. Normally, the dashboard starts refreshing them in parallel, but depending on the speed of your computer and the network latencies, charts start having a slight time difference. Setting this to Resync will attempt to re-synchronize the charts on every update. Setting it to Best Effort may lower the pressure on your browser and the network.

Sync hover selection on all charts?
When enabled, a selection on one chart will automatically select the same time on all other visible charts and the legends of all visible charts will be updated to show the selected values. When disabled, only the chart getting the user's attention will be selected. Enable it to get better insights of the data. Disable it if you are on a very slow computer that cannot actually do it.

| Sync pan and zoom on all charts? When enabled, pan and zoom operations on a chart will be replicated to all charts (even the ones that are not currently visible - of course only when they will become visible). When disabled, pan and zoom operations will not be propagated to other charts.

| Which theme to use? Netdata comes with two themes: Dark (the default) and White. Switching this will reload the dashboard.
| Do you need help? Netdata can show some help in some areas to help you use the dashboard. If all these balloons bother you, disable them using this switch. Switching this will reload the dashboard.

Enable data padding when panning and zooming?
When set to Pad the charts will be padded with more data, both before and after the visible area, thus giving the impression the whole database is loaded. This padding will happen only after the first pan or zoom operation on the chart (initially all charts have only the visible data). When set to Don't Pad only the visible data will be transfered from the netdata server, even after the first pan and zoom operation.

| Enable Bézier lines on charts? When set to Smooth the charts libraries that support it, will plot smooth curves instead of simple straight lines to connect the points. Keep in mind dygraphs, the main charting library in netdata dashboards, can only smooth line charts. It cannot smooth area or stacked charts. When set to Rough, this setting can lower the CPU resources consumed by your browser.

These settings are applied gradually, as charts are updated. To force them, refresh the dashboard now.
| Enable auto-scaling of select units? When set to Scale Units the values shown will dynamically be scaled (e.g. 1000 kilobits will be shown as 1 megabit). Netdata can auto-scale these original units: `kilobits/s`, `kilobytes/s`, `KB/s`, `KB`, `MB`, and `GB`. When set to Fixed Units all the values will be rendered using the original units maintained by the netdata server.
| Which units to use for temperatures? Set the temperature units of the dashboard.
| Convert seconds to time? When set to Time, charts that present `seconds` will show `DDd:HH:MM:SS`. When set to Seconds, the raw number of seconds will be presented.

Show browser local time or server time?
When set to Your Time, the charts will use your browser local time. When set to Server Time the charts will use the server time.
Set it to Your Time to have a common time-reference, no matter where the server is and which time zone it uses (all your dashboards will report your local time). Set it to Server Time when you need to compare netdata charts with server log files.
Your browser time zone is: -.
The server reported timezone is: - (you can set this in netdata.conf `[global].timezone`).
The current time zone on the dashboard is: -.
