Workaround for the Event Log (Windows API) sensor issue

Event Log (Windows API) sensors might not work anymore after Windows updates of June 2021 because of security hardening changes for the Event Tracing for Windows (ETW) that relate to the security vulnerability issue CVE-2021-31958. For more information on this issue, see https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-31958.

We are aware of this issue and we are already working on a solution. As a workaround, please use the WMI Event Log sensor instead. This sensor should cover most of your needs until we can provide you with a solution.
