Causal Modeling based Fault Localization in Cloud Systems using Golden Signals

In cloud-native applications, a large fraction of operational failures, known as outages, result in violations of Service Level Objectives (SLOs). SLOs are defined around specific measurable characteristics: availability, throughput, frequency, response time, and quality. Four metrics, latency, traffic, errors, and saturation, ensure coverage for most outages of an application. These are often cal...
