Linux Metrics

This page outlines the specific Linux 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.

Captured Data Overview

Category Details Captured
Performance Metrics CPU, memory, disk, and network stats from system tools
Operating System OS name, version, architecture, kernel version
Installed Software Application inventory from RPM, DPKG, and Snap packages
System Configuration Hostname, timezone, kernel, environment, logged-in users
SQL Server Instances Edition, version, install method (RPM/DPKG), and presence verification
Network Connections Active connections with local/remote IP, ports, and owning processes
Process Inventory Running processes and associated binaries
Package Source Info Package manager details: source, version, vendor
Error Diagnostics Timestamped logs related to failures in collection processes
