How do I set up Prometheus for monitoring my application?

To set up Prometheus, you'll need to install it and configure a YAML file to specify the targets you want to monitor.

What should I include in the configuration file?

In the configuration file, include the scrape_configs section, where you define the job name and the targets to scrape metrics from.

Can you give me an example of a scrape configuration?

Sure! Here's a simple example:

scrape_configs:
  - job_name: 'my_app'
    static_configs:
      - targets: ['localhost:8080']

How do I verify that Prometheus is collecting metrics?

You can verify it by accessing the Prometheus web UI at http://localhost:9090/targets and checking the status of your targets.
