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.
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, 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. 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 on our community forums.
