Monitor Kong Gateway performance and connection management. Track request processing, latency, and error rates.
To use this dashboard, configure Kong Gateway to send metrics to SigNoz using the OpenTelemetry plugin. Follow the Kong Gateway Integration guide to get started.

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.
- Use Query Builder to explore your Kong metrics in detail.
