For visibility on ChromeOS hosts, Fleet provides the fleetd Chrome extension which provides similar functionality as osquery on other operating systems.
> The fleetd Chrome browser extension is supported on ChromeOS operating systems that are managed using [Google Admin](https://admin.google.com). It is not intended for non-ChromeOS hosts with the Chrome browser installed.
By default, the hostname for a Chromebook host will be blank. The hostname can be customized in Google Admin under Devices > Chrome > Settings > Device > Device Settings > Other Settings > [Device network hostname template](https://support.google.com/chrome/a/answer/1375678#zippy=%2Cdevice-network-hostname-template%2Creport-device-os-information).
See our [fleetd Chrome extension testing docs](https://github.com/fleetdm/fleet/blob/main/docs/Contributing/getting-started/testing-and-local-development.md#fleetd-chrome-extension) for debugging instructions.
