Any number of nodes and every available metric." +custom_edit_url: https://github.com/netdata/netdata/edit/master/docs/quickstart/infrastructure.md +--> + +# Infrastructure monitoring with Netdata + +[Netdata Cloud](https://app.netdata.cloud) provides scalable infrastructure monitoring for any number of distributed +nodes running the Netdata Agent. A node is any system in your infrastructure that you want to monitor, whether it's a +physical or virtual machine (VM), container, cloud deployment, or edge/IoT device. + +The Netdata Agent uses zero-configuration collectors to gather metrics from every application and container instantly, +and uses Netdata's [distributed data architecture](/docs/store/distributed-data-architecture.md) to store metrics +locally. Without a slow and troublesome centralized data lake for your infrastructure's metrics, you reduce the +resources you need to invest in, and the complexity of, monitoring your infrastructure. + +Netdata Cloud unifies infrastructure monitoring by _centralizing the interface_ you use to query and visualize your +nodes' metrics, not the data. By streaming metrics values to your browser, with Netdata Cloud acting as the secure proxy +between them, you can monitor your infrastructure using customizable, interactive, and real-time visualizations from any +number of distributed nodes. + +In this quickstart guide, you'll learn the basics of using Netdata Cloud to monitor an infrastructure with dashboards, +composite charts, and alarm viewing. You'll then learn about the most critical ways to configure the Agent on each of +your nodes to maximize the value you get from Netdata. + +This quickstart assumes you've installed the Netdata Agent on more than one node in your infrastructure, and connected +those nodes to your Space in Netdata Cloud. If you haven't yet, see the [Netdata +Cloud](https://learn.netdata.cloud/docs/cloud) docs for details on signing up for Netdata Cloud, installation, and +connection process. + +> If you want to monitor a Kubernetes cluster with Netdata, see our [k8s installation +> doc](/packaging/installer/methods/kubernetes.md) for setup details, and then read our guide, [_Monitor a Kubernetes +> cluster with Netdata_](/docs/guides/monitor/kubernetes-k8s-netdata.md). + +## Set up your Netdata Cloud experience + +Start your infrastructure monitoring experience by setting up your Netdata Cloud account. + +### Organize Spaces and War Rooms + +Spaces are high-level containers to help you organize your team members and the nodes they can view in each War Room. +You already have at least one Space in your Netdata Cloud account. + +A single Space puts all your metrics in one easily-accessible place, while multiple Spaces creates logical division +between different users and different pieces of a large infrastructure. For example, a large organization might have one +SRE team for the user-facing SaaS application, and a second IT team for managing employees' hardware. Since these teams +don't monitor the same nodes, they can work in separate Spaces and then further organize their nodes into War Rooms. + +Next, set up War Rooms. Netdata Cloud creates dashboards and visualizations based on the nodes added to a given War +Room. You can [organize War Rooms](https://learn.netdata.cloud/docs/cloud/war-rooms#war-room-organization) in any way +you want, such as by the application type, for end-to-end application monitoring, or as an incident response tool. + +Learn more about [Spaces](https://learn.netdata.cloud/docs/cloud/spaces) and [War +Rooms](https://learn.netdata.cloud/docs/cloud/war-rooms), including how to manage each, in their respective reference +documentation. + +### Invite your team + +Netdata Cloud makes an infrastructure's real-time metrics available and actionable to all organization members. By +inviting others, you can better synchronize with your team or colleagues to understand your infrastructure's heartbeat. +When something goes wrong, you'll be ready to collaboratively troubleshoot complex performance problems from a single +pane of glass. + +To [invite new users](https://learn.netdata.cloud/docs/cloud/manage/invite-your-team), click on **Invite Users** in the +Space management Area. Choose which War Rooms to add this user to, then click **Send**. + +If your team members have trouble signing in, direct them to the [Netdata Cloud sign +in](https://learn.netdata.cloud/docs/cloud/manage/sign-in) doc. + +### See an overview of your infrastructure + +The default way to visualize the health and performance of an infrastructure with Netdata Cloud is the +[**Overview**](/docs/visualize/overview-infrastructure.md), which is the default interface of every War Room. The +Overview features composite charts, which display aggregated metrics from every node in a given War Room. These metrics +are streamed on-demand from individual nodes and composited onto a single, familiar dashboard. + + + +Read more about the Overview in the [infrastructure overview](/docs/visualize/overview-infrastructure.md) doc. + +Netdata Cloud also features the [**Nodes view**](https://learn.netdata.cloud/docs/cloud/visualize/nodes), which you can +use to configure and see a few key metrics from every node in the War Room, view health status, and more. + +### Drill down to specific nodes + +Both the Overview and Nodes view offer easy access to **single-node dashboards** for targeted analysis. You can use +single-node dashboards in Netdata Cloud to drill down on specific issues, scrub backward in time to investigate +historical data, and see like metrics presented meaningfully to help you troubleshoot performance problems. + +Read about the process in the [infrastructure +overview](/docs/visualize/overview-infrastructure.md#drill-down-with-single-node-dashboards) doc, then learn about [interacting with +dashboards and charts](/docs/visualize/interact-dashboards-charts.md) to get the most from all of Netdata's real-time +metrics. + +### Create new dashboards + +You can use Netdata Cloud to create new dashboards that match your infrastructure's topology or help you diagnose +complex issues by aggregating correlated charts from any number of nodes. For example, you could monitor the system CPU +from every node in your infrastructure on a single dashboard. + + + +Read more about [creating new dashboards](/docs/visualize/create-dashboards.md) for more details about the process and +additional tips on best leveraging the feature to help you troubleshoot complex performance problems. + +## Set up your nodes + +You get the most value out of Netdata Cloud's infrastructure monitoring capabilities if each node collects every +possible metric. For example, if a node in your infrastructure is responsible for serving a MySQL database, you should +ensure that the Netdata Agent on that node is properly collecting and streaming all MySQL-related metrics. + +In most cases, collectors autodetect their data source and require no configuration, but you may need to configure +certain behaviors based on your infrastructure. Or, you may want to enable/configure advanced functionality, such as +longer metrics retention or streaming. + +### Configure the Netdata Agent on your nodes + +You can configure any node in your infrastructure if you need to, although most users will find the default settings +work extremely well for monitoring their infrastructures. + +Each node has a configuration file called `netdata.conf`, 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](/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 infrastructure's nodes](/docs/configure/secure-nodes.md) using +one of our recommended methods. These security best practices ensure no untrusted parties gain access to the metrics +collected on any of your nodes. + +### Collect metrics from systems and applications + +Netdata has [300+ pre-installed collectors](/collectors/COLLECTORS.md) that gather thousands of metrics with zero +configuration. Collectors search each of your nodes in default locations and ports to find running applications and +gather as many metrics as they can without you having to configure them individually. + +Most collectors work without configuration, but you should read up on [how collectors +work](/docs/collect/how-collectors-work.md) and [how to enable/configure](/docs/collect/enable-configure.md) them so +that you can see metrics from those applications in Netdata Cloud. + +In addition, find detailed information about which [system](/docs/collect/system-metrics.md), +[container](/docs/collect/container-metrics.md), and [application](/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 nodes and troubleshoot complex performance problems. +Once you have a handle on configuration and are collecting all the right metrics, try out some of Netdata's other +infrastructure-focused features: + +- [See an overview of your infrastructure](/docs/visualize/overview-infrastructure.md) using Netdata Cloud's composite + charts and real-time visualizations. +- [Create new dashboards](/docs/visualize/create-dashboards.md) from any number of nodes and metrics in Netdata Cloud. + +To change how the Netdata Agent runs on each node, dig in to configuration files: + +- [Change how long nodes in your infrastructure retain metrics](/docs/store/change-metrics-storage.md) based on how + many metrics each node collects, your preferred retention period, and the resources you want to dedicate toward + long-term metrics retention. +- [Create new alarms](/docs/monitor/configure-alarms.md), or tweak some of the pre-configured alarms, to stay on top + of anomalies. +- [Enable notifications](/docs/monitor/enable-notifications.md) to Slack, PagerDuty, email, and 30+ other services. +- [Export metrics](/docs/export/external-databases.md) to an external time-series database to use Netdata alongside + other monitoring and troubleshooting tools. + +### Related reference documentation + +- [Netdata Cloud · Spaces](https://learn.netdata.cloud/docs/cloud/spaces) +- [Netdata Cloud · War Rooms](https://learn.netdata.cloud/docs/cloud/war-rooms) +- [Netdata Cloud · Invite your team](https://learn.netdata.cloud/docs/cloud/manage/invite-your-team) +- [Netdata Cloud · Sign in or sign up with email, Google, or + GitHub](https://learn.netdata.cloud/docs/cloud/manage/sign-in) +- [Netdata Cloud · Nodes view](https://learn.netdata.cloud/docs/cloud/visualize/nodes) + + diff --git a/docs/quickstart/single-node.md b/docs/quickstart/single-node.md new file mode 100644 index 0000000..7855a48 --- /dev/null +++ b/docs/quickstart/single-node.md @@ -0,0 +1,92 @@ +<!-- +title: "Single-node monitoring with Netdata" +sidebar_label: "Single-node monitoring" +description: "Learn dashboard basics, configuring your nodes, and collecting metrics from applications to create a powerful single-node monitoring tool." +custom_edit_url: https://github.com/netdata/netdata/edit/master/docs/quickstart/single-node.md +--> + +# 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.
