This dashboard provides monitoring of Envoy Proxy performance using OpenTelemetry Stat Sink, giving you visibility into traffic patterns, connection handling, and internal server health.
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
