<!-- --- title: "Collecting metrics" custom_edit_url: https://github.com/netdata/netdata/edit/master/collectors/README.md --- --> # Collecting metrics Netdata can collect metrics from hundreds of different sources, be they internal data created by the system itself, or external data created by services or applications. To see _all_ of the sources Netdata collects from, view our [list of supported collectors](/collectors/COLLECTORS.md), and then view our [quickstart guide](/collectors/QUICKSTART.md) to get up-and-running. There are two essential points to understand about how collecting metrics works in Netdata: - All collectors are **installed by default** with every installation of Netdata. You do not need to install collectors manually to collect metrics from new sources. - Upon startup, Netdata will **auto-detect** any application or service that has a [collector](/collectors/COLLECTORS.md), as long as both the collector and the app/service are configured correctly. Most users will want to enable a new Netdata collector for their app/service. For those details, see our [quickstart guide](/collectors/QUICKSTART.md). ## Take your next steps with collectors [Collectors quickstart](/collectors/QUICKSTART.md) [Supported collectors list](/collectors/COLLECTORS.md) [Collectors configuration reference](/collectors/REFERENCE.md) ## Guides [Monitor Nginx or Apache web server log files with Netdata](/docs/guides/collect-apache-nginx-web-logs.md) [Monitor CockroadchDB metrics with Netdata](/docs/guides/monitor-cockroachdb.md) [Monitor Unbound DNS servers with Netdata](/docs/guides/collect-unbound-metrics.md) [Monitor a Hadoop cluster with Netdata](/docs/guides/monitor-hadoop-cluster.md) ## Related features **[Dashboards](/web/README.md)**: Vizualize your newly-collect metrics in real-time using Netdata's [built-in dashboard](/web/gui/README.md). **[Backends](/backends/README.md)**: Extend our built-in [database engine](/database/engine/README.md), which supports long-term metrics storage, by archiving metrics to like Graphite, Prometheus, MongoDB, TimescaleDB, and more. **[Exporting](/exporting/README.md)**: An experimental refactoring of our backends system with a modular system and support for exporting metrics to multiple systems simultaneously.
