Implementing custom metrics

The metrics provided by value-added cloud services, such as Function-as-a-service, are a great starting point. Teams can put their cloud-native services into production with just these metrics with a reasonable level of confidence. However, more observability is almost always better. We need fine-grained details about the inner workings of our functions. This recipe demonstrates how to collect additional metrics, such as cold starts, memory, CPU utilization, and the latency of HTTP resources.
