• Cloud hosted applications are now composed of many microservices often deployed in containers. When things go wrong, are slow, or just not understood, where can we turn?

    Jaeger https://github.com/jaegertracing/jaeger is one such tool but requires instrumentation code to be placed in the source code prior to deployment.

    Using Linux bcc/BPF tracing tools https://github.com/iovisor/bcc and Salt, instrumentation code can be remotely injected anywhere in the cloud "on-the-fly" without requiring prior source code modification.

    Salt https://github.com/saltstack/salt is used in both the "tracer injection" and "tracer data collection" phases to facilitate Jaeger code flow tracing.

Slide Deck Presentation:


  • sluicegate --> sluicebox implemented as an actual salt returner
  • Jaeger “tag” support
  • regex style event filtering by sluice_gate for traces
  • Implement a direct python debugger (pdb) “sluice-style” tracer
  • Span, tag, reporting and collation by sluice_box
  • Optimize the salt client for passing sluicegate events to sluicebox
  • more, better, “jaeger friendly” BPF tracing tools
