update collector
October 17, 2025 ยท View on GitHub
The update collector exposes the Windows Update service metrics. Note that the Windows Update service (wuauserv) must be running, else metric collection will fail.
The Windows Update service is responsible for managing the installation of updates for the operating system and other Microsoft software. The service can be configured to automatically download and install updates, or to notify the user when updates are available.
