CPU Saturation Incident
High latency in front-end service caused by CPU saturation on node3. Here's how Coroot identified the root cause and provided the fix.
Coroot's Root Cause Analysis
Root Cause: CPU saturation on node3 caused high latency in the front-end service, affecting catalog and db-main services.
The front-end service experienced significant latency increases due to CPU resource contention. The catalog service and db-main database were also impacted by the CPU starvation. An analytics-updater job running on node3 was consuming significant CPU resources, contributing to the resource bottleneck.
