Monitoring with SLOs and error budgets
WHAT IT TESTS: SRE reliability targets. OUTLINE: define SLIs from the user's view, set SLO targets, derive an error budget, and alert on burn rate rather than raw thresholds. RED FLAG: paging on every CPU blip with no link to user impact.
WHAT IT TESTS: whether you frame reliability around users and budgets, not noisy thresholds. ANSWER OUTLINE: pick Service Level Indicators reflecting user experience such as success rate and latency; set Service Level Objectives as targets over a window; the allowed unreliability is the error budget; alert on how fast you burn that budget so pages reflect real user impact. Benefits: less alert fatigue, a data-driven basis for trading features against reliability, and clearer prioritization. RED FLAG: alerting on raw resource metrics.
