winwmi

Sample code to get WMI metrics from a Windows system using Go.

This is really just a simple layout on how it's done. It would need to be taylored to capture what's needed.

The metrics captured are helpful in system right-sizing for a cloud migration from on-prem to Azure or AWS (for example).

These are the basic metrics that are needed for clound migration.

Cloud Metrics

  • Currently Configured

    • Configured CPUs
    • Processor Speed
    • Configured RAM (GiB)
    • OS Type and Level

  • Trend Over Time (5-minute samples minimum)

    • CPU Used (%)
    • CPU Used (#)
    • CPU Demand (VMware)
    • Active memory
    • Consumed Memory
    • File cache memory
    • Storage Capacity Total
    • Storage Capacity Used
