On-call receives an alert storm from one root failure cascading across municipal microservices. What observability practice reduces duplicate pages from that single incident?
Select an answer to reveal the explanation.
Short Explanation
One snapped power line can make every house’s lights blink—and every detector scream. Correlation groups those screams so on-call sees one incident, not fifty clones. Without it, cascade failures bury the root cause under noise.
Full Explanation
Alert correlation and aggregation reduce duplicate notifications when one failure fans out across dependent services. Storms obscure root cause and exhaust responders. Designing observability with grouping, dependency awareness, or suppression of children under a parent incident improves operational response quality.
