Role Variables

This role uses three variables all of them has default values, these variables are:

• prometheus_version: The version of prometheus to install default is 2.4.2

• prometheus_scrape_interval: The interval at which targets are scarped default is 15s

• prometheus_jobs: This variable is an array, it defines the jobs used by prometheus and their respective instances default value is:

  - name: prometheus
    targets:
      - localhost:9090
  

  This means that prometheus will only monitor it self, to add more jobs and instances use this syntax:

  - name: node
    targets:
      - "server1:9100"
      - "server2:9100"
  - name: mysql
    targets:
      - "dbserver1:9104"
      - "dbserver2:9104"
  

  Adding new jobs and instances is super easy just add them to prometheus_jobs and run the role again
