# 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.

## Netdata collectors

These collectors are recursive in nature, in that they monitor some function of the Netdata Agent itself. Some
collectors are described only in code and associated charts in Netdata dashboards.

-   [ACLK (code only)](https://github.com/netdata/netdata/blob/master/aclk/legacy/aclk_stats.c): View whether a Netdata
    Agent is connected to Netdata Cloud via the [ACLK](/aclk/README.md), the volume of queries, process times, and more.
-   [Alarms](https://learn.netdata.cloud/docs/agent/collectors/python.d.plugin/alarms): This collector creates an
    <strong>Alarms</strong> menu with one line plot showing the alarm states of a Netdata Agent over time.
-   [Anomalies](https://learn.netdata.cloud/docs/agent/collectors/python.d.plugin/anomalies): This collector uses the
    Python PyOD library to perform unsupervised anomaly detection on your Netdata charts and/or dimensions.
-   [Exporting (code only)](https://github.com/netdata/netdata/blob/master/exporting/send_internal_metrics.c): Gather
    metrics on CPU utilization for the [exporting engine](/exporting/README.md), and specific metrics for each enabled
    exporting connector.
-   [Global statistics (code only)](https://github.com/netdata/netdata/blob/master/daemon/global_statistics.c): See
    metrics on the CPU utilization, network traffic, volume of web clients, API responses, database engine usage, and
    more.

## Orchestrators

Plugin orchestrators organize and run many of the above collectors.

the `go.d.plugin`.

default. To use a third-party collector, visit their GitHub/documentation page and follow their installation procedures.
