Envoy Monitoring
What Is Envoy?
Envoy is an open-source edge and service proxy, designed for cloud-native applications and microservices architectures. It plays a pivotal role in managing ingress and egress traffic between microservices, thus ensuring seamless communications within distributed systems. As a Layer 7 proxy, it provides advanced load balancing, traffic management, and observability features, crucial for high-availability applications.

Why Is Envoy Monitoring Important?
Monitoring Envoy is critical to ensure the reliability and performance of your service-mesh infrastructure. It allows you to:
- Detect and resolve bottlenecks.
- Optimize resource utilization.
- Maintain service quality by identifying connection issues.
- Achieve application resilience through proactive monitoring.
What Are The Benefits Of Using Envoy Monitoring Tools?
Utilizing tools for monitoring Envoy offers several advantages:
- Real-Time Monitoring: Gain immediate insights into traffic patterns and proxy performance.
- Comprehensive Metrics: Monitor server states, connection rates, and memory usage.
- Alerting: Receive notifications of critical issues to mitigate service disruptions.
- Scalability: Easily monitor multiple Envoy instances across a distributed environment.
Understanding Envoy Performance Metrics
Netdata collects a rich set of metrics from Envoy, enabling detailed monitoring of server, cluster, and listener performance:
Envoy Server Metrics
- envoy.server_state: Tracks the server’s current operational state.
- envoy.server_connections_count: Monitors the number of active connections.
- envoy.server_memory_allocated_size: Measures server memory allocation.
- envoy.server_uptime: Time duration for which the server has been running.
Envoy Cluster Metrics
- envoy.cluster_manager_cluster_count: Shows the number of active clusters.
- envoy.cluster_membership_endpoints_count: Monitors the status of cluster members based on health.
Envoy Listener Metrics
- envoy.listener_manager_listeners_count: Observes the total number of configured listeners.
- envoy.listener_downstream_cx_active_count: Current count of active downstream connections.
Table of Key Envoy Metrics
| Metric Name | Description |
|---|---|
| envoy.server_state | Current state of the Envoy server. |
| envoy.server_connections_count | Number of current active connections. |
| envoy.server_memory_allocated_size | Memory allocated by the server. |
| envoy.server_uptime | Uptime of the server in seconds. |
| envoy.cluster_manager_cluster_count | Active clusters managed by Envoy. |
| envoy.cluster_membership_endpoints_count | Number of cluster endpoints and their statuses. |
| envoy.listener_manager_listeners_count | Count of active listeners in the manager. |
| envoy.listener_downstream_cx_active_count | Active downstream connections. |
Advanced Envoy Performance Monitoring Techniques
Advanced monitoring involves integrating more sophisticated metrics analysis, such as rate of changes in listener and cluster configurations. By analyzing trends in connection failures or memory usage, DevOps teams can preemptively adjust configurations to avoid service outages.
Diagnose Root Causes Or Performance Issues Using Key Envoy Statistics & Metrics
Using Netdata’s in-depth metrics, it’s possible to quickly diagnose the root causes of bottlenecks and performance issues. For example, monitoring the increase in envoy.cluster_upstream_cx_connect_fail_rate can hint at connectivity problems, while a rising envoy.server_memory_heap_size might indicate a memory leak.
