Fit assessment process

As explained in Google Anthos in Action

A fit assessment process is a structured procedure for discovering workload characteristics, evaluating migration suitability, and reporting results.

A fit assessment process determines whether a workload can migrate to a container. It uses mfit, a Linux CLI, plus Linux and Windows data-collection scripts to gather evidence and produce suitability scores and remediation recommendations. section 15.4.1

Run the assessment in three phases:

  • Discovery gathers VM inventory, configuration, operating-system details, services, processes, and installed packages into a local database under ~/.mfit. Inventory discovery through the vSphere API is optional; guest-level collection uses Bash for Linux or PowerShell for Windows. section 15.4.1
  • Assessment uses the collected data with mfit to evaluate migration suitability. section 15.4.1
  • Reporting generates results containing a fit score and recommendations for resolving migration obstacles. section 15.4.1

Typical CLI sequence

Discover vSphere inventory with ./mfit discover vsphere, collect guest data with the Linux or Windows script, import archives when necessary, run ./mfit assess, and export HTML or JSON using ./mfit report.

How Google Anthos in Action covers it

How deep it goes
Defines discovery, assessment, and reporting, then details collection paths and CLI outputs without explaining scoring internals.
Examples
Uses vSphere discovery, Linux and Windows collection scripts, archive imports, assessment commands, and HTML or JSON reports.
What it assumes
Assumes VM access and optionally vCenter access, while supplying collection methods for Linux and Windows guests.
What you can do after
Evaluate migration suitability and export actionable findings for resolving obstacles before container migration.
How it connects
Connects workload migration with virtual machines, containers, vSphere API, SSH, and guest operating systems.
