Case Study: Yext achieves 70% fewer SLO violations and near-real-time root-cause analysis with LightStep

Yext Moves to LightStep, Improving Application Performance

Yext, the digital knowledge management company, struggled with latency and limited visibility as its multi-language microservices and growing data volumes made production performance issues hard to diagnose. After trying other APM tools that sampled traces and gave only partial views, Yext selected LightStep’s always-on distributed tracing and observability platform to get end-to-end visibility, real-time SLO alerts, and faster root-cause analysis.

LightStep was deployed in days and provided account-specific performance omniscience, intelligent sampling, and SLO alerting integrated with Slack and PagerDuty. Using LightStep, Yext cut the percent of page views outside SLOs by 70%, reduced a top customer’s page loads outside target by 90%, saved roughly one week per month (about 12 weeks annually) in diagnostics, and now monitors top accounts with custom SLOs for faster remediation.
