-# Single-node monitoring with Netdata
-
-Because it's free, open-source, and requires only 1% CPU utilization to collect thousands of metrics every second,
-Netdata is a superb single-node monitoring tool.
-
-In this quickstart guide, you'll learn how to access your single node's metrics through dashboards, configure your node
-to your liking, and make sure the Netdata Agent is collecting metrics from the applications or containers you're running
-on your node.
-
-## See your node's metrics
-
-To see your node's real-time metrics, you need to access its dashboard. You can either view the local dashboard, which
-runs on the node itself, or see the dashboard through Netdata Cloud. Both methods feature real-time, interactive, and
-synchronized charts, with the same metrics, and use the same UI.
-
-The primary difference is that Netdata Cloud also has a few extra features, like creating new dashboards using a
-drag-and-drop editor, that enhance your monitoring and troubleshooting experience.
-
-To see your node's local dashboard, open up your web browser of choice and navigate to `http://NODE:19999`, replacing
-`NODE` with the IP address or hostname of your Agent. Hit `Enter`. 
-
-![Animated GIF of navigating to the
-dashboard](https://user-images.githubusercontent.com/1153921/80825153-abaec600-8b94-11ea-8b17-1b770a2abaa9.gif)
-
-To see a node's dashboard in Netdata Cloud, [sign in](https://app.netdata.cloud). From the **Nodes** view in your
-**General** War Room, click on the hostname of your node to access its dashboard through Netdata Cloud.

-
-Once you've decided which dashboard you prefer, learn about [interacting with dashboards and
-charts](https://github.com/netdata/netdata/blob/master/docs/visualize/interact-dashboards-charts.md) to get the most from Netdata's real-time metrics.
-
-## Configure your node
-
-The Netdata Agent is highly configurable so that you can match its behavior to your node. You will find most
-configuration options in the `netdata.conf` file, which is typically at `/etc/netdata/netdata.conf`. The best way to
-edit this file is using the `edit-config` script, which ensures updates to the Netdata Agent do not overwrite your
-changes. For example:
-
-```bash
-cd /etc/netdata
-sudo ./edit-config netdata.conf
-```
-
-Our [configuration basics doc](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md) contains more information about `netdata.conf`, `edit-config`,
-along with simple examples to get you familiar with editing your node's configuration.
-
-After you've learned the basics, you should [secure your node](https://github.com/netdata/netdata/blob/master/docs/configure/secure-nodes.md) using one of our
-recommended methods. These security best practices ensure no untrusted parties gain access to your dashboard or its
-metrics.
-
-## Collect metrics from your system and applications
-
-Netdata has [300+ pre-installed collectors](https://github.com/netdata/netdata/blob/master/collectors/COLLECTORS.md) that gather thousands of metrics with zero
-configuration. Collectors search your node in default locations and ports to find running applications and gather as
-many metrics as possible without you having to configure them individually.
-
-These metrics enrich both the local and Netdata Cloud dashboards.
-
-Most collectors work without configuration, but you should read up on [how collectors
-work](https://github.com/netdata/netdata/blob/master/docs/collect/how-collectors-work.md) and [how to enable/configure](https://github.com/netdata/netdata/blob/master/docs/collect/enable-configure.md) them.
-
-In addition, find detailed information about which [system](https://github.com/netdata/netdata/blob/master/docs/collect/system-metrics.md),
-[container](https://github.com/netdata/netdata/blob/master/docs/collect/container-metrics.md), and [application](https://github.com/netdata/netdata/blob/master/docs/collect/application-metrics.md) metrics you can
-collect from across your infrastructure with Netdata.
-
-## What's next?
-
-Netdata has many features that help you monitor the health of your node and troubleshoot complex performance problems.
-Once you understand configuration, and are certain Netdata is collecting all the important metrics from your node, try
-out some of Netdata's other visualization and health monitoring features:
-
--   [Build new dashboards](https://github.com/netdata/netdata/blob/master/docs/visualize/create-dashboards.md) to put disparate but relevant metrics onto a single
-    interface.
--   [Create new alarms](https://github.com/netdata/netdata/blob/master/docs/monitor/configure-alarms.md), or tweak some of the pre-configured alarms, to stay on top
-    of anomalies.
--   [Enable notifications](https://github.com/netdata/netdata/blob/master/docs/monitor/enable-notifications.md) to Slack, PagerDuty, email, and 30+ other services.
--   [Change how long your node stores metrics](https://github.com/netdata/netdata/blob/master/docs/store/change-metrics-storage.md) based on how many metrics it
-    collects, your preferred retention period, and the resources you want to dedicate toward long-term metrics
-    retention.
--   [Export metrics](https://github.com/netdata/netdata/blob/master/docs/export/external-databases.md) to an external time-series database to use Netdata alongside
-    other monitoring and troubleshooting tools.
