There is varying support for collectors on each operating system. The tables
below list all existing collectors and the supported systems.
Which collectors are used is controlled by the `--collectors.enabled` flag.
Collectors are enabled by providing a `--collector.<name>` flag.
Collectors that are enabled by default can be disabled by providing a `--no-collector.<name>` flag.
### Enabled by default
