Introduction to Node.js

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)?

Get rid of pushgateway
Saturation - Load testing to determine upper threshold (up 10 rq/sec)
Imminent
Should we use summeries
- Historical
- There might be situation where you don't care about aggregation
Historgrams
- Use up to 10 bukcets
- Some use cases if you don't know the
Aggregations, quantile, timewindow at query time

For excessively paranoid client authentication.
