The USE method

The USE method was introduced by Brendan Gregg.

Utilization: disk,CPU usage …
Saturation: disk I/O, ...
Errors: network interface errors, ...

Great example when applied to resources like host CPU & Memory, or caches.

The RED method

The RED method was introduced by Tom Wilkie. It's a subset of “The Four Golden Signals” that’s focused on micro-service architectures and which includes these metrics:

Rate: the number of requests our service is serving per second;
Error: the number of failed requests per second;
Duration: the amount of time it takes to process a request;

The CASE method

The CASE method was introduced by Cory Watson.

Symptom based:

The seven golden signals

The seven golden signals was introduced by Baron Schwartz.

CELT + USE method aka the seven golden signals

Concurrency: number of simultaneous requests
Error rate: errors/sec
Latency: response time, queue/wait time
Throughput: query per seconds (QPS)
