I have no idea what I am talking about 😜

Why Distributed Tracing?

  • Distributed microservices
  • Hard to debug process flow in conventional tracing
  • context propagation

OpenTracing + OpenCensus

=

OpenTelemetry

Before we get started

  • It's okay to not know python for this talk. You can use the same prinsiples in other languages too
  • How many of you are comfortable with containers?
  • How many of you are comfortable with gRPC?
  • Have anyone use traefik before?

Specification 101

  • Span
  • Traces
  • SpanContext

OpenTelemetry Data Model

Causal relationships between Spans in a single Trace


        [Span A]  ←←←(the root span)
            |
     +------+------+
     |             |
 [Span B]      [Span C] ←←←(Span C is a `ChildOf` Span A)
     |             |
 [Span D]      +---+-------+
               |           |
           [Span E]    [Span F] >>> [Span G] >>> [Span H]
                                       ↑
                                       ↑
                                       ↑
                         (Span G `FollowsFrom` Span F)

Visualize Traces with a time axis

Temporal relationships between Spans in a single Trace


––|–––––––|–––––––|–––––––|–––––––|–––––––|–––––––|–> time

 [Span A············································]
   [Span B·······································]
      [Span D··································]
    [Span C·································]
         [Span E·······]  [Span F··] [Span G··] [Span H··]
