Configure Prometheus Monitoring Targets

To configure monitoring targets in Prometheus, you need to edit the configuration file prometheus.yml. In this file, you can add the targets to monitor and their respective configuration information.

Here is an example of a Prometheus.yml configuration file:

global:
  scrape_interval: 15s

scrape_configs:
  - job_name: 'node_exporter'
    static_configs:
      - targets: ['localhost:9100']

  - job_name: 'my_app'
    static_configs:
      - targets: ['my_app_host:9101']

In this example, we have defined two monitoring targets, namely node_exporter and my_app. Each monitoring target has a job_name and a targets list, which includes the hosts and ports to be monitored.

Once the editing is complete, save and restart the Prometheus service to apply the changes. Prometheus will begin collecting metric data from the targets defined in the configuration file and storing it in a time series database for monitoring and analysis.
