This blog post is aimed at GoLang developers who are looking to improve the observability of their services. It skips the basics and jumps straight to advanced topics, such as asynchronous structured logging, metrics with exemplars, tracing with TraceQL, aggregating pprof and continuous profiling, microbenchmarks and basic statistics with benchstat, blackbox performance tests, and basic PID controllers for determining a system's maximum load. We'll also briefly touch on current research in the observability space, including active casual profiling and passive critical section detection.
