How deeply does Cloud Observability in Action cover burn rate?

Defines the metric and names Prometheus tooling, but stops short of detailed calculation or implementation.

Burn rate

As explained in Cloud Observability in Action

A burn rate is the rate at which a service consumes its error budget relative to the permitted rate.

Burn rate measures how quickly a service consumes its error budget relative to the permitted rate. Error budgets provide remaining tolerance against an SLO; burn rate shows the speed of its depletion. section 10.1.3

Operational use

Prometheus-based tools such as Pyrra and Sloth can generate SLO rules, metrics, and alerts that expose error-budget consumption and burn rates. Teams can then choose the tool that best fits their requirements rather than adopting every SLO feature. section 10.2.2 section 10.4

Burn rate belongs to the SLO workflow: SLIs measure service behavior, SLOs establish goals, and error budgets quantify permitted failure. It can support more accurate, trend-based alerts, but detailed terminology and implementation are deferred. section 10.1.3 section 10.4
