How do I configure scraping in Prometheus?

To configure scraping in Prometheus, you need to edit the prometheus.yml file. You can define scrape jobs under the scrape_configs section.

What is a scrape job?

A scrape job is a configuration that tells Prometheus where to scrape metrics from, including the target endpoint and the frequency.

Can you give me an example of a scrape job configuration?

Sure! Here's a simple example:

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

This config scrapes metrics from a service running on localhost at port 8080.

How can I set the scrape interval?

You can set the scrape interval by adding the scrape_interval field to your scrape job configuration. For example:

scrape_configs:
  - job_name: 'my_service'
    scrape_interval: 15s
    static_configs:
      - targets: ['localhost:8080']
