Windows Metrics
This page outlines the specific Windows guest metrics collected by DMC, along with the exact commands used during execution. In line with our commitment to transparency, every metric is listed here for your review.
DMC is designed to collect only the data necessary for cloud migration planning — no PII, no application-level data, and no unnecessary system details. All collected data can be reviewed locally before anything is uploaded, ensuring you retain full visibility and control.
