Is there a Fact gathering module?

[lpereira1]

Im trying to write some automation around UCS vnics and some of the defaults are causing me issues. Is there a facts module somewhere I can use so I can verify information before I make a change via the playbook.

Specifically, I added some vlans into a vnic template and the mtu was changed because the default is 1500 and I run another value.

Hi @lpereira1,

You can use the ucs_query module to pull facts about a particular configuration or classid. It is very simple to use and provides a lot of detail that you will need to parse through. I use this module pretty heavily for auditing configuration. Here is an example of how I audit our ucs_vlans configuration (in our repo) against what is running on the actual system:

- hosts: all
  connection: local
  gather_facts: no
  vars:
  # vlan_list: []
    login_info: &login_info
      hostname: "{{ ucs_hostname }}"
      username: "{{ ucs_username }}"
      password: "{{ ucs_password }}"  
  
  tasks:
  - name: "COLLECT VLAN DETAILS FROM {{ ucs_hostname |upper }}"
    cisco.ucs.ucs_query:
      <<: *login_info
      class_ids: fabricVlan
    register: fabricVlan
  
  - set_fact:
      ucs_vlan_running_config: "{{ ucs_vlan_running_config | default({}) | combine ({ item.name : item.id }) }}"
    loop: "{{ fabricVlan.objects.fabricVlan }}"

  - set_fact:
      ucs_vlan_intended_config: "{{ ucs_vlan_intended_config | default({}) | combine ({ item.name : item.id }) }}"
    loop: "{{ ucs_vlans }}"
  
  - name: FIND VLAN DIFF (INTENDED VS RUNNING)
    set_fact:
      extra_vlans: "{{ (ucs_vlan_running_config | difference(ucs_vlan_intended_config)) }}"
      missing_vlans: "{{ (ucs_vlan_intended_config | difference(ucs_vlan_running_config)) }}"
    # no_log: true

  - name: "EXTRA VLANS"
    debug:
      msg: "{{ extra_vlans | ternary('VLANS TO DELETE/CHECK:', 'NO EXTRA VLANS') }}{{ extra_vlans|default(omit) }}"

  - name: "MISSING VLANS"
    debug:
      msg: "{{ missing_vlans | ternary('MISSING VLANS:', 'NO VLANS ARE MISSING') }}{{ missing_vlans|default(omit) }}"

For auditing vnics or vnic_template configuration, I think you'll need to use class_ids: vnicEther or class_ids: vnicLanConnTempl. I was planning on writing a query for something similar but I just haven't gotten around to it yet.

I hope this helps.
