Description
Reasoning
Being able to collect statistics on Windows containers would greatly benefit rAdvisor and allow it to become a universal tool for collecting container resource utilization statistics with fine granularity and low overhead.
Background
The current implementation of rAdvisor relies on the Linux kernel and its functionality in cgroups. Since first-party containerization functionality was added to Windows 10/Windows Server 2016, it is now possible to run and monitor Windows containers running on a Windows host.
While most of the code in the rAdvisor project is platform agnostic (such as timing, cli parsing, polling, logging, shell), the core cgroups resolution / collection code relies on the public interfaces of cgroups, and as such, won't work on Windows. docker stats seems to support Windows in its collecton (it has Windows-specific fields in its Stats schema).
There is a Rust binding library for Host Compute Services (HCS), the Windows kernel component used to support containerization:
