Target hostname not being set on scrape config

[bmgante]

Hi,

Any idea why when installing prometheus using this ansible role it sometimes sets target with the right hostname and sometimes sets localhost as per image below (in the same instance)?

prometheus_scrape_configs:
  - job_name: "prometheus"
    metrics_path: "{{ prometheus_metrics_path }}"
    static_configs:
      - targets:
          - "{{ ansible_fqdn | default(ansible_host) | default('localhost') }}:9090"
