+title: "Supported collectors list"
+description: "Netdata gathers real-time metrics from hundreds of data sources using collectors. Most require zero configuration and are pre-configured out of the box."

+
+# Supported collectors list
+
+Netdata uses collectors to help you gather metrics from your favorite applications and services and view them in
+real-time, interactive charts. The following list includes collectors for both external services/applications and
+internal system metrics.
+
+Learn more about [how collectors work](/docs/collect/how-collectors-work.md), and then learn how to [enable or
+configure](/docs/collect/enable-configure.md) any of the below collectors using the same process.
+
+Some collectors have both Go and Python versions as we continue our effort to migrate all collectors to Go. In these
+cases, _Netdata always prioritizes the Go version_, and we highly recommend you use the Go versions for the best
+experience.
+
+If you want to use a Python version of a collector, you need to explicitly [disable the Go
+version](/docs/collect/enable-configure.md), and enable the Python version. Netdata then skips the Go version and
+attempts to load the Python version and its accompanying configuration file.
+
+If you don't see the app/service you'd like to monitor in this list, check out our [GitHub
+issues](https://github.com/netdata/netdata/issues). Use the search bar to look for previous discussions about that
+collector—we may be looking for contributions from users such as yourself! If you don't see the collector there, make a
+[feature request](https://community.netdata.cloud/c/feature-requests/7/none) on our community forums.

+collectors are described only in code and associated charts in Netdata dashboards.
+

+ is connected to Netdata Cloud via the [ACLK](/aclk/README.md), the volume of queries, process times, and more.

+ <strong>Alarms</strong> menu with one line plot showing the alarm states of a Netdata Agent over time.

+ Python PyOD library to perform unsupervised anomaly detection on your Netdata charts and/or dimensions.

+ metrics on CPU utilization for the [exporting engine](/exporting/README.md), and specific metrics for each enabled

+
+## Orchestrators
+
+Plugin orchestrators organize and run many of the above collectors.
+
+If you're interested in developing a new collector that you'd like to contribute to Netdata, we highly recommend using
+the `go.d.plugin`.

+These collectors are developed and maintained by third parties and, unlike the other collectors, are not installed by
+default. To use a third-party collector, visit their GitHub/documentation page and follow their installation procedures.
