5 The presentation stage: displaying telemetry

 

This chapter covers

  • The function of the Presentation Stage
  • Aggregating and displaying metrics data
  • Features needed in centralized logging and security systems
  • How correlation drives observability and distributed tracing
Figure 5.1 The telemetry pipeline stages with the Presentation Stage last. The Presentation Stage consumes storage from the Shipping Stage, and presents it to people to support decisions. The Presentation Stage has access to all of the Shipping Stage storage, allowing it to enrich telemetry beyond what the previous two stages were able to provide

The Presentation Stage is the last stage of the telemetry pipeline and also is the stage most people in the technical organization (and outside of it) use to interact with telemetry. This chapter teaches how telemetry is presented in each of the five telemetry system styles covered in previous chapters:

  • Section 5.1 covers metrics systems and how charts and aggregations are produced.
  • Section 5.2 covers centralized logging systems and what features a good presentation system for centralized logging should have.
  • Section 5.3 covers security systems and their specialized presentation needs.
  • Section 5.4 covers both observability and distributed tracing systems and how correlation drives the value both systems provide.
