Real-Time Database Monitoring: Solving Database Latency with Zero-Code eBPF Tracing

eBPF-based instrumentation (OBI by Coralogix) can eliminate the observability blind spot between application and database layers without any code changes or sidecars. By deploying as a Kubernetes DaemonSet, OBI intercepts database traffic at the Linux kernel/syscall boundary and decodes protocols like Couchbase's binary protocol and SQL++ (N1QL) in real time. It enriches telemetry with Kubernetes context, database targets, and operation metadata, then emits OpenTelemetry-compatible metrics and spans. The workflow covers a Database Catalog for RED metrics, trace deep-dives to isolate slow queries, and trace-to-log correlation to reduce MTTR.
