How LLM Teams Can Cut Alert Fatigue Using Burn-Rate and Level-Triggered Rules

Most LLM monitoring setups rely on simple latency and error-rate thresholds that trigger too frequently, leading teams to mute alerts within days. A more effective approach uses level-triggered alerts, which fire only when a system has been in a bad state for a sustained period rather than on any single anomalous data point. Engineers are advised to page only for conditions actively harming users — such as outright failures, severe slowdowns, or unexpected cost spikes — while routing degraded-but-recovering signals to a ticket queue instead. The recommended framework borrows from Google's SRE practices, using multi-window burn-rate rules tied to an error budget to detect both fast outages and slow quality decay. Because all alert thresholds derive from a single SLO parameter, adjusting the reliability target automatically recalibrates every rule without manual re-tuning.
