Information

During the development of version 0.30, the windows_exporter underwent significant modernization. We plan to deliver a stable release by mid-2025, with upcoming changes—including a newly designed Hyper-V collector—enhancing the value of the official 1.0 stable release.

✨ Breaking Changes

windows_exporter introduced another wave of breaking changes due to limited maintainer capacity to maintain backward compatibility. Please note that windows_exporter uses Semantic Versioning (semver), and backward compatibility is not guaranteed for versions below 1.0.

Windows Management Infrastructure (MI) as a Replacement for Windows Management Instrumentation (WMI)

As of version 0.30.0, windows_exporter no longer uses WMI directly. Instead, it leverages its successor, Windows Management Infrastructure (MI), available since Windows Server 2012. MI provides several advantages, such as the ability to run queries in parallel.

New Hyper-V collector

The Hyper-V collector got a full rewrite and now using Performance Data API instead WMI. This should result into a faster collect time. However, a lot metric names has been changed.

Performance Data Helpers

windows_exporter 0.30 uses Performance Data Helpers instead of parsing binary data directly from the registry. This update also introduces support for Process V2, which is enabled by default on Windows Server 2022. Due to known issues with the Process V1 collector, the registry-based collector remains in use.

Windows Server 2025

In version 0.30, windows_exporter adopts a new Docker base image: mcr.microsoft.com/oss/kubernetes/windows-host-process-containers-base-image. This new Docker image eliminates the need to build dedicated images for each version of Windows OS.

performancecounter Collector

windows_exporter now supports a generic performancecounter collector. This new collector allows users to extend monitoring capabilities independently. Please note that the performancecounter collector is still in an experimental state.
