This dashboard provides monitoring of Envoy Proxy performance using OpenTelemetry Stat Sink, giving you visibility into traffic patterns, connection handling, and internal server health.
✅ Info
To use this dashboard, you need to configure Envoy to send metrics to SigNoz. Follow the Envoy Metrics guide to get started.

Dashboard Variables
This dashboard includes pre-configured variables for filtering:
- namespace: Filter by Kubernetes namespace
- service.name: Filter by specific service name
- cluster: Filter by upstream cluster name
- deployment_environment: Filter by deployment environment (e.g., production, staging)
What This Dashboard Monitors
This dashboard provides comprehensive monitoring of Envoy Proxy performance, giving you visibility into:
- Request patterns and throughput: Track incoming requests, response times, and data transfer rates
- Connection health: Monitor active connections, connection lifecycle, and upstream cluster status
- Error tracking: Identify and analyze 4xx/5xx errors with detailed breakdowns
- Resource usage: Keep tabs on Envoy's memory consumption and heap size
- Upstream performance: Monitor backend cluster health, connection failures, and error rates
