I recently read "Cloud Native DevOps with Kubernetes" by O'reily and it mentions the RED and USE metrics which are a good starting point for gaining better observability into the system, however I'm having a hard time finding any information online about how to actually go about generating those metrics outside of re-inventing the wheel for each service.
Is there a set of libraries to actually generate RED and USE metrics within the application? Or do we have to create a set of utilities for each language and each service independently?
Also, are there known solutions for sending CrashLoopBack or Pending pod metrics to Prometheus or do these also need to be reinvented in house?
