RED & USE

If it’s a resource, like a queue, instrument it according to Brendan Gregg’s USE method: utilization, saturation, and error count (rate). If it’s something like an endpoint, instrument it according to Tom Wilkie’s RED method: request count (rate), error count (rate), and duration.

For every resource, check utilization, saturation, and errors.
