Mensurae

This project is a re-imagining of system measurement tools for open-source operating systems.

It is the successor to my PmcTools project for FreeBSD in 2005.  The PmcTools project (also known as ‘HWPMC’, from the name of its kernel module) offers a way for applications to use in-CPU hardware performance counters to measure system and application behavior.

About the Project Name

Mensurae is the nominative plural of the Latin noun mensura (‘measurement’), i.e., with the meaning ‘measurements’. Mensurae is also the future active participle form of the Latin verb metiri (‘to measure’), i.e., with the meaning ‘going to measure’.  Both these meanings fit the goals of the project.

Current Status

At this point I am:

• Collecting wishlists from PmcTools users and incorporating these in my planning; please see: ‘An Invitation To Collaborate’.

• Preparing the initial set of documents for the work ahead.

  I prefer a documentation-centric process for software development that I call ‘Documentation Driven Development’.

Documentation Groups

Note	This section is a work-in-progress.

• Usage Examples

  These examples explore how Mensurae’s tools and APIs would be used in practice.

  These use-cases inform the design of the data formats, tools and APIs.

• Design Goals

  High-level requirements and design goals for the framework.

• Reference Documentation

  To be written.

• User Documentation
