Overview
Prometheus-based metrics instrumentation for connector node components, covering source/sink connections, throughput, and resource usage.
Description
Connector Observability provides comprehensive metrics instrumentation for the Java connector node using Prometheus client libraries. It exposes counters, gauges, and histograms for connection tracking (active sources, active sinks, total connections), throughput measurement (rows received, rows written), resource usage (CPU, heap memory), and error tracking. These metrics are scraped by Prometheus and visualized in Grafana dashboards, enabling operators to monitor connector health, detect bottlenecks, and diagnose failures in production CDC and sink pipelines.
Usage
Apply this principle when adding new connector types that need monitoring, extending existing metrics, or building alerting rules for connector health.
