Prometheus Questions

• metric names
  • Should the same metrics, e.g. requests_total be used across all http services or should one introduce a prefix for services?
  • What are the scaling considerations for an approach as the above
  • What if there's a load balancer and services where a request would be increase two counter, e.g. nginx_lb_requests_total and some_service_requests_total?
• Series churn
• When series churn happens and you have two time series, e.g. http_requests_total{code="200"} and http_requests_total{code="500"} are two new series created when the new prometheus container scrapes that target (not sure if same storage is mounted in k8s)?

openssl req -new -x509 -days 365 -key ca.key -out ca.crt
