Configure Prometheus server to scrape the exporter

Variables

When calling the role, configure these variables:

• inventory_hostname - this is Ansible built-in variable and will be used to specify host to scrape
• exporter_port - port used by the exporter which will be opened on the node
• prometheus_config - file where to add new target to scrape

In inventory file, you also need prometheus group with one server.

Example

- name: "Scrape Tower exporter"
  include_role:
    name: add-prometheus-target
  vars:
    prometheus_config: /root/prometheus/targets/tower.yml
    exporter_port: 443
