What does the USE method measure for infrastructure monitoring?

  • AUtilization, Saturation, and Errors — three signals that cover how busy a resource is, whether it has queued work, and whether it is failing
  • BUptime, Scalability, and Efficiency — three metrics that track system availability, growth capacity, and resource optimization overhead
  • CUsage, Stability, and Exceptions — three indicators that measure resource consumption, system reliability, and failure occurrences overall
  • DUtilization, Speed, and Errors — three dimensions that cover resource load, processing latency, and failure rates across all components

Why this is the answer

USE was designed by Brendan Gregg for infrastructure components like CPU, memory, and disks. Unlike RED which targets request-driven services, USE focuses on physical or logical resources and catches bottlenecks before they affect end users.
