RED Method

A request-centric monitoring approach tracking Rate, Errors, and Duration for every service.

Definition

RED, proposed by Tom Wilkie, suits microservices: measure requests per second, the number of failing requests, and the distribution of request latency. It is a subset of the golden signals focused on services.

Example

A Grafana panel per microservice shows request rate, error rate, and p95 duration.

Exam tip

RED is for services; USE is for resources such as CPU, disks, and network interfaces.
