gRPC monitoring is crucial for managing high-performance, distributed systems. It involves collecting multiple types of data from diverse sources to identify and troubleshoot issues in microservices communication frameworks like gRPC. The framework works well with microservices that transfer a lot of data, supports real-time streaming, and has built-in security features. However, there are different approaches to monitoring gRPC, including code instrumentation using frameworks like OpenTelemetry, automatic instrumentation, and eBPF, which is a modern methodology for collecting monitoring data in an efficient and scalable way. To get the most out of gRPC monitoring, it's essential to choose the right tools and frameworks, optimize for performance and scalability, make the most of your data, keep things secure, and consider taking gRPC monitoring to the next level by using eBPF and APM tools.
