Scalpels

Scalpels is distributed tracing or digging system for OpenStack.

Background

OpenStack is made of multiple Python-based projects. Each project has similiar but different architecture. Scalpels gathers useful scripts or 3rd tools to help operator find what happen in your cloud.

Contribute

This project is prototype now and under development. If you have interests in this work, please contact @kun_huang, at #openstack-chinese channel.

Mission

Scalpels is kind of "debugfs" for OpenStack. It gathers data from number of tracers like proc or systemtap which could be used to quantize preformance under workloads.

Single Node Architecture

This type of deployment is used as POC in OpenStack community CI.

All-in-One deployment

Multiple Node Architecture

This is under Designing:

Multiple deployment

Agent-Tracer-Worker

The relationship is:

Ideas

Each project will have scripts working:

  • on python calls
  • on sql queries
  • on filesystem I/O
  • on RPC calls if need
  • on necessary system calls
  • on common system statistics
