Layer 7 Observability with Consul Service Mesh

The new L7 observability features in Consul Connect, introduced in Consul 1.5, provide deeper insight into the behavior and performance of services by enabling monitoring of protocol-specific error rates and response codes. This allows for better correlation of events and identification of failures in production. By configuring metrics collection through a centralized configuration file, users can collect L7 metrics from Envoy proxies in a consistent way, regardless of programming language or framework. The features also support distributed tracing and integration with tools like Grafana to provide a comprehensive view of system performance.
