Monitor Kong Gateway performance and connection management. Track request processing, latency, and error rates.

Dashboards → + New dashboard → Import JSON
After import, the Total Requests and Active Connections panels should populate immediately if Kong is sending metrics to SigNoz.
Tracked Metrics
Metric panels require Kong Gateway Enterprise v3.13+. Traces are available with Kong Gateway 3.0+ and logs with 3.8+ (Enterprise or OSS).
- Request Traffic: Track incoming requests and request rates.
- Latency: Monitor request, upstream, and Kong internal latencies (p50, p90, p99) to find bottlenecks.
- Error Tracking: View 5xx error rates by service and 4xx errors by status code.
- Server Performance: Track active connections and database connectivity.
- Upstream Health: Monitor upstream target status.
- Resource Management: Check bandwidth usage by service and Lua shared dictionary memory utilization.
Dashboard Panels
Overview Metrics
- Total Requests: Complete count of requests.
- Request Rate (req/s): Incoming requests per second.
- Active Connections: Active network connections.
- DB Connected: Connection status of the configured database.
Request Metrics
- Request Rate by Service: Request rates for each configured service.
- Requests by HTTP Status Code: Requests grouped by HTTP status code.
Latency Metrics
- Request Latency (p50 / p90 / p99): End-to-end request latency distribution.
- Upstream Latency (p50 / p90 / p99): Latency distribution for upstream requests.
- Kong Internal Latency (p50 / p90 / p99): Latency introduced by Kong's internal processing.
Error Metrics
- 5xx Error Rate by Service: 5xx server-side errors across different services.
- 4xx Errors by Status Code: 4xx client-side errors by status code.
Traffic & Network
- Bandwidth by Service (bytes/s): Network throughput consumed by each service.
- Active Nginx Connections: Live NGINX connection counts.
Health & Resources
- Upstream Target Health: Upstream target status.
- Lua Shared Dict Memory: Memory utilization of Kong's Lua shared dictionaries.
Next Steps
- Set up alerts to notify you of high upstream latency or error rates.
