Setting up prometheus endpoint into prometheus portal/Grafana

[kisalay19]

This is a general query and not an issue but more of a help needed in understanding how to push results to prometheus.

Below is my setup in Startup.cs

app.UseHealthChecksPrometheusExporter("/prometheus");

On browsing this endpoint I can see the page in Prometheus text format. Now how do I visualize or link this data in the actual prometheus environment or Grafana.

1. I have a local environment of Prometheus running through docker in my system http://localhost:9090
2. I have a local environment of Grafana running through docker in my system http://localhost:3030

Below are the references I am using in my .NET Core API :

1. Microsoft.AspNetCore.Diagnostics.HealthChecks 2.2.0
2. Microsoft.Extensions.Diagnostics.HealthChecks 3.1.4
3. AspNetCore.HealthChecks.Prometheus.Metrics 3.1.3

@kisalay19 you need to configure prometheus to scrap the output, typically by providing a prometheus.yml

`global: scrape_interval: 15s evaluation_interval: 15s

A scrape configuration containing exactly one endpoint to scrape.

scrape_configs:

• job_name: 'serviceexporter' scrape_interval: 5s static_configs:
  • targets: ['someservice:9110']`

i added this:

metrics_path: '/health_metrics' 

if you use 

            app.UseHealthChecksPrometheusExporter("/health_metrics");

so because you use /prometheus

            app.UseHealthChecksPrometheusExporter("/prometheus");

you should add

metrics_path: '/prometheus' 

to your yaml file as prometheus configuration file

result something like this:

job_name: 'health_check_exporter'
    scrape_interval: 5s
    metrics_path: '/prometheus' 
    static_configs:
    targets: ['someservice:9110']`

i suggest use this for grafana dashboard :
