Most require zero configuration and are pre-configured out of the box." +custom_edit_url: https://github.com/netdata/netdata/edit/master/collectors/COLLECTORS.md +--> + +# 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. + +- [Service and application collectors](#service-and-application-collectors) + - [APM (application performance monitoring)](#apm-application-performance-monitoring) + - [Containers and VMs](#containers-and-vms) + - [Data stores](#data-stores) + - [Distributed computing](#distributed-computing) + - [Email](#email) + - [Kubernetes](#kubernetes) + - [Logs](#logs) + - [Messaging](#messaging) + - [Network](#network) + - [Provisioning](#provisioning) + - [Remote devices](#remote-devices) + - [Search](#search) + - [Storage](#storage) + - [Web](#web) +- [System collectors](#system-collectors) + - [Applications](#applications) + - [Disks and filesystems](#disks-and-filesystems) + - [eBPF (extended Berkeley Packet Filter)](#ebpf) + - [Hardware](#hardware) + - [Memory](#memory) + - [Networks](#networks) + - [Processes](#processes) + - [Resources](#resources) + - [Users](#users) +- [Netdata collectors](#netdata-collectors) +- [Orchestrators](#orchestrators) +- [Third-party collectors](#third-party-collectors) +- [Etc](#etc) + +## Service and application collectors + +The Netdata Agent auto-detects and collects metrics from all of the services and applications below.
