Glovo, a subsidiary of Delivery Hero operating in 23 countries, uses Grafana's Traces Drilldown to improve their incident response and root cause analysis in distributed systems. Tracing provides a crucial visualization of request flows, highlighting bottlenecks and dependencies in complex microservice architectures. During a recent incident involving cascading failures, engineers at Glovo utilized Traces Drilldown to efficiently identify and resolve the issue, which stemmed from a rate-limited product catalog API affecting checkout processes. This tool enabled them to filter and analyze traces without complex queries, leading to a quick resolution and preventing further disruptions. Traces Drilldown has since become integral to their Site Reliability Engineering (SRE) workflows, allowing for more effective identification and troubleshooting of errors and latency issues.
