Case Study: Leading Web Search Company achieves fast root cause identification with InsightFinder

Fast Root Cause Zone Identification through Cluster Outlier Detection

Leading Web Search Company, a global query service operator with 13 replication zones worldwide, suffered a major outage that took more than two days to diagnose because existing monitoring could not identify where the problem started. The company needed help localizing the root cause in its geo-redundant environment, especially after a network switch issue in one zone triggered cascading failures across all zones.

InsightFinder used its Metric File Replay agent and multivariate anomaly detection to analyze all zones together and quickly pinpoint the culprit zone showing high query errors and low network bandwidth before the outage. InsightFinder helped the customer identify the outlier zone much earlier than its existing tools, reducing troubleshooting from days to a much faster root-cause process and providing lead time to prevent a catastrophic service failure.
