Bluepill Design

Here are just some bullet points of the design. We'll add details later.

  • Each process monitors a single application, so you can have multiple bluepill processes on a system
  • Use rotational arrays for storing historical data for monitoring process conditions
  • Memo-ize output of ps per tick as an optimization for applications with many processes
  • Use socket files to communicate between CLI and daemon
  • DSL is a separate layer, the core of the monitoring just uses regular initializers, etc. DSL is simply for ease of use and should not interfere with business logic
  • Sequentially process user issued commands so no weird race cases occur
  • Triggers are notified by the state machine on any process state transitions
