Metrics on Kubernetes with Prometheus #5

Open talon-vonneudeck opened 7 years ago

talon-vonneudeck commented 7 years ago

This a nice overview. Thanks for making it.

Prometheus is not built-in as a running server, but service discovery and metrics are all exported by default. So when you start a Prometheus inside a Kubernetes cluster with a "this is a kubernetes cluster"-option, you will see that it will gather plenty of metrics by default. So it feels very smooth and almost as if it was completely built-in. That is definitely worth mentioning. It is also very easy to activate service discovery for the prometheus metrics of the software you deploy to the cluster. Just add a specific annotation to the pods, done.

Hi @talon-vonneudeck, do you have a source backing that? It does like a very interesting option considering what you mentioned. I'll try to add it over the weekend.

Here. The Kubernetes part starts at slide no. 26: https://www.slideshare.net/brianbrazil/monitoring-kubernetes-with-prometheus-kubernetes-ireland-2016
