Technical Preview

windows_exporter is undergoing a modernization. We plan to deliver a stable release by mid-2025, with upcoming changes—including a newly designed Hyper-V collector—adding value to the official 1.0 stable release.

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 utilizes its successor, Windows Management Infrastructure (MI), available since Windows Server 2012. MI offers several advantages, such as the ability to run queries in parallel.

Performance Data Helpers

When the environment variable WINDOWS_EXPORTER_PERF_COUNTERS_ENGINE=pdh or CLI flag --perfcounter.engine=pdh is set, windows_exporter uses Performance Data Helpers instead of the Registry. This change also introduces support for Process V2, which is enabled by default on Windows Server 2022.
