Instrumentation is how you add metrics to source code and applications that you control. Instrumenting code with the metrics that are important to you allows them to be used in graphs and alerts within Prometheus.
This course looks at the philosophy and approach to take when instrumenting, and how to then instrument your code.
This is the seventh part of a multi-course series on Prometheus fundamentals.
