How to monitor Linkerd the microservices proxy

The article explores the deployment and monitoring of Linkerd, an open-source service mesh proxy, within a Kubernetes cluster, addressing the complexities of microservices communication and traceability. Linkerd serves as a scalable solution to manage network logic such as retries, timeouts, and TLS tunneling, thereby simplifying microservices architecture by abstracting service discovery and enabling dynamic request routing. To effectively monitor Linkerd, the article highlights the integration of Sysdig Monitor, which facilitates comprehensive visibility into microservices communication through statsd teleport, capturing real-time metrics like request latency and service health. Linkerd's deployment options, including convoy mode and DaemonSet, are detailed alongside its capability to support distributed tracing systems like Zipkin, aiding in the observation of latency across different microservices. The importance of configuring alerts for service latency, connection failures, and retries budget is emphasized to ensure optimal performance and reliability in microservices environments.
