Hi all,

I’ve started my journey into understanding how the whole Prometheus system work.  
The team I’m working with have setup a Prometheus Operator through kube-prometheus-stack and its doing a lot of magic behind the scenes that has gotten me slightly confused.

One of the thing I am interested and unable to find much is the affects of kuberentes annotations on Prometheus’s scraping logic.  
In the configuration file, we have this service discovery in the scrape config.

```auto
- job_name: kubernetes-pods
  honor_timestamps: true
  scrape_interval: 30s
  scrape_timeout: 10s
  metrics_path: /metrics
  scheme: http
  follow_redirects: ......

```

Now I understand that this is going to scrape everything at metrics path `/metrics`.  
However, it is also scraping Envoy metrics at path `/stats/prometheus` which I cannot comprehend.

After searching the whole config file, I see nothing that says to look into `/stats/prometheus` for the metrics. However, I found in the annotation of the pod that there is the annotation `prometheus.io/path: /stats/prometheus`.

I’m assuming that this has something to do with how Prometheus decides where it scrapes.  
Sadly, this is the only clue I have and I’m not sure where to find the docs that talks about this.

If anyone has any idea on how I can better clear myself of the whole system’s logic, I would very much appreciate it.  
Thanks y’all
