RED vs USE vs Golden Signals — which methodology?

medium

Answer

$RED (Requests / Errors / Duration): request-driven services (API, ML inference).$
$USE (Utilization / Saturation / Errors): resource-focused (CPU, disk, GPU).$
$Golden Signals (Google SRE): Latency / Traffic / Errors / Saturation — combines both perspectives.$
$Best practice: RED for services + USE for infrastructure + Golden Signals as top-level.$
$All three complement; not either/or.$

Check yourself — multiple choice

Same
RED: services (Req/Err/Dur); USE: resources (Util/Sat/Err); Golden Signals: combined SRE view; use all three complementary — RED for service + USE for infra + Golden for top-level
Random
Not real

RED (services) + USE (resources) + Golden (top-level) = complementary.
