While you can use it as an +effective standalone tool, we also designed it to be open and interoperable with other tools you might already be using. + +Netdata helps you collect everything and scales to infrastructure of any size, but it doesn't lock-in data or force you +to use specific tools or methodologies. Each feature is extensible and interoperable so they can work in parallel with +other tools. For example, you can use Netdata to collect metrics, visualize metrics with a second open-source program, +and centralize your metrics in a cloud-based time-series database solution for long-term storage or further analysis. + +You can build a new monitoring stack, including Netdata, or integrate Netdata's metrics with your existing monitoring +stack. No matter which route you take, Netdata helps you monitor infrastructure of any size. + +Here are a few ways to enrich your existing monitoring and troubleshooting stack with Netdata: + +## Collect metrics from Prometheus endpoints + +Netdata automatically detects 600 popular endpoints and collects per-second metrics from them via the [generic +Prometheus collector](https://learn.netdata.cloud/docs/agent/collectors/go.d.plugin/modules/prometheus). This even +includes support for Windows 10 via [`windows_exporter`](https://github.com/prometheus-community/windows_exporter). + +This collector is installed and enabled on all Agent installations by default, so you don't need to waste time +configuring Netdata. Netdata will detect these Prometheus metrics endpoints and collect even more granular metrics than +your existing solutions. You can now use all of Netdata's meaningfully-visualized charts to diagnose issues and +troubleshoot anomalies. + +## Export metrics to external time-series databases + +Netdata can send its per-second metrics to external time-series databases, such as InfluxDB, Prometheus, Graphite, +TimescaleDB, ElasticSearch, AWS Kinesis Data Streams, Google Cloud Pub/Sub Service, and many others. + +To [export metrics to external time-series databases](/docs/export/external-databases.md), you configure an [exporting +_connector_](/docs/export/enable-connector.md). These connectors support filtering and resampling for granular control +over which metrics you export, and at what volume. You can export resampled metrics as collected, as averages, or the +sum of interpolated values based on your needs and other monitoring tools. + +Once you have Netdata's metrics in a secondary time-series database, you can use them however you'd like, such as +additional visualization/dashboarding tools or aggregation of data from multiple sources. + +## Visualize metrics with Grafana + +One popular monitoring stack is Netdata, Graphite, and Grafana. Netdata acts as the stack's metrics collection +powerhouse, Graphite the time-series database, and Grafana the visualization platform. With Netdata at the core, you can +be confident that your monitoring stack is powered by all possible metrics, from all possible sources, from every node +in your infrastructure. + +Of course, just because you export or visualize metrics elsewhere, it doesn't mean Netdata's equivalent features +disappear. You can always build new dashboards in Netdata Cloud, drill down into per-second metrics using Netdata's +charts, or use Netdata's health watchdog to send notifications whenever an anomaly strikes. + +## What's next? + +Whether you're using Netdata standalone or as part of a larger monitoring stack, the next step is the same: [**Get +Netdata**](/docs/get/README.md). + +[](<>) diff --git a/docs/overview/what-is-netdata.md b/docs/overview/what-is-netdata.md new file mode 100644 index 00000000..8ee0db41 --- /dev/null +++ b/docs/overview/what-is-netdata.md @@ -0,0 +1,76 @@ +<!-- +title: "What is Netdata?" +description: "Netdata is distributed, real-time performance and health monitoring for systems and applications on a single node or an entire infrastructure." +custom_edit_url: https://github.com/netdata/netdata/edit/master/docs/overview/what-is-netdata.md +--> + +# What is Netdata? + +Netdata helps sysadmins, SREs, DevOps engineers, and IT professionals collect all possible metrics from systems and +applications, visualize these metrics in real-time, and troubleshoot complex performance problems. + +Netdata's solution uses two components, the Netdata Agent and Netdata Cloud, to deliver real-time performance and health +monitoring for both single nodes and entire infrastructure. + +## Netdata Agent + +Netdata's distributed monitoring Agent collects thousands of metrics from systems, hardware, and applications with zero +configuration. It runs permanently on all your physical/virtual servers, containers, cloud deployments, and edge/IoT +devices. + +You can [install](/docs/get/README.md#install-the-netdata-agent) Netdata on most Linux distributions (Ubuntu, Debian, +CentOS, and more), container/microservice platforms (Kubernetes clusters, Docker), and many other operating systems +(FreeBSD, macOS), with no `sudo` required. + + + +## Netdata Cloud + +Netdata Cloud is a web application that gives you real-time visibility for your entire infrastructure. With Netdata +Cloud, you can view key metrics, insightful charts, and active alarms from all your nodes in a single web interface. +When an anomaly strikes, seamlessly navigate to any node to troubleshoot and discover the root cause with the familiar +Netdata dashboard. + +**[Netdata Cloud is +free](https://learn.netdata.cloud/docs/cloud/faq-glossary#how-much-does-netdata-cost-how-and-why-is-it-free)**! You can +add an entire infrastructure of nodes, invite all your colleagues, and visualize any number of metrics, charts, and +alarms entirely for free. + +While Netdata Cloud offers a centralized method of monitoring your Agents, your metrics data is not stored or +centralized in any way. Metrics data remains with your nodes and is only streamed to your browser, through Cloud, when +you're viewing the Netdata Cloud interface. + + + +## What you can do with Netdata + +Netdata is designed to be both simple to use and flexible for every monitoring, visualization, and troubleshooting use +case: + +- **Collect**: Netdata collects all available metrics from your system and applications with 300+ collectors, + Kubernetes service discovery, and in-depth container monitoring, all while using only 1% CPU and a few MB of RAM. It + even collects metrics from Windows machines. +- **Visualize**: The dashboard meaningfully presents charts to help you understand the relationships between your + hardware, operating system, running apps/services, and the rest of your infrastructure. Add nodes to Netdata Cloud + for a complete view of your infrastructure from a single pane of glass. +- **Monitor**: Netdata's health watchdog uses hundreds of preconfigured alarms to notify you via Slack, email, + PagerDuty and more when an anomaly strikes. Customize with dynamic thresholds, hysteresis, alarm templates, and + role-based notifications. +- **Troubleshoot**: 1s granularity helps you detect analyze anomalies other monitoring platforms might have missed. + Interactive visualizations reduce your reliance on the console, and historical metrics help you trace issues back to + their root cause. +- **Store**: Netdata's efficient database engine efficiently stores per-second metrics for days, weeks, or even + months. Every distributed node stores metrics locally, simplifying deployment, slashing costs, and enriching + Netdata's interactive dashboards. +- **Export**: Integrate per-second metrics with other time-series databases like Graphite, Prometheus, InfluxDB, + TimescaleDB, and more with Netdata's interoperable and extensible core. +- **Stream**: Aggregate metrics from any number of distributed nodes in one place for in-depth analysis, including + ephemeral nodes in a Kubernetes cluster. + +## What's next? + +Learn more about [why you should use Netdata](/docs/overview/why-netdata.md), or [how Netdata works with your existing +monitoring stack](/docs/overview/netdata-monitoring-stack.md). + +[](<>) diff --git a/docs/overview/why-netdata.md b/docs/overview/why-netdata.md new file mode 100644 index 00000000..27a30a4c --- /dev/null +++ b/docs/overview/why-netdata.md @@ -0,0 +1,63 @@ +<!-- +title: "Why use Netdata?" +description: "Netdata is simple to deploy, scalable, and optimized for troubleshooting.
