Ansible bigip_device_facts - Filter Output

Hi, I'm new to ansible and have installed ansible version 2.7 and I'm trying to understand how I can filter the output from the new bigip_device_facts module as bigip_facts are depreciated. I ha...

    The result from bigip_device_facts contains a list of dictionaries. It can be processed in a number of ways depending on the output you want, but here's a simple example how to print the output with debug:

      - bigip_device_facts:
      provider: "{{ provider_vars }}"
      gather_subset:
        - vlans
    register: gathered_facts

  - name: "Debug vlans"
    debug:
      msg: "VLAN {{ item.name }} has tag {{ item.tag }}"
    with_items: "{{ gathered_facts.vlans }}"

Hi,

 

It was my fault. I was using as variable the 'ltm-pool' option from gather_subset instead of the 'ltm_pool' from the output of the registered facts. It works as expected.

 

Thanks!

Hi all, I am having another issue obtaining filtered information from this module. With the given example, I can use the item.* for referencing the subfields under 'vlans'.

"bigip_device_facts": {
    "changed": true, 
    "failed": false, 
    "vlans": [
        {
            "auto_lasthop": "default", 
            "cmp_hash_algorithm": "default", 
            "failsafe_action": "failover-restart-tm", 
            "failsafe_enabled": "no", 
            "failsafe_timeout": 90, 
            "full_path": "/Common/F5TEST", 
            "if_index": 96, 
            "learning_mode": "enable-forward", 
            "mtu": 1500, 
            "name": "F5TEST", 
            "sflow_poll_interval": 0, 
            "sflow_poll_interval_global": "yes", 
            "sflow_sampling_rate": 0, 
            "sflow_sampling_rate_global": "yes", 
            "source_check_enabled": "disabled", 
            "tag": 2015, 
            "true_mac_address": "00:11:22:33:44:55"

But, if I use the subset 'ltm-pools', there is another sublevel under members.

"bigip_device_facts": {
    "changed": true, 
    "failed": false, 
    "ltm_pools": [
        {
            "allow_nat": "yes", 
            "allow_snat": "yes", 
            "client_ip_tos": "pass-through", 
            "client_link_qos": "pass-through", 
            "full_path": "/Common/mypool", 
            "ignore_persisted_weight": "no", 
            "lb_method": "round-robin", 
            "members": [
                {
                    "address": "192.168.10.10", 
                    "connection_limit": 0, 
                    "dynamic_ratio": 1, 
                    "ephemeral": "no", 
                    "fqdn_autopopulate": "no", 
                    "full_path": "/Common/myhost:8080", 
                    "inherit_profile": "yes", 
                    "logging": "no", 
                    "monitors": [], 
                    "name": "myhost:8080", 
                    "partition": "Common", 
                    "priority_group": 0, 
                    "rate_limit": "no", 
                    "ratio": 1, 
                    "state": "disabled"
                },

I want to extract only 'name' and 'state', but it remains in the previous level.

- name: "LTM_POOLS OUTPUT"
  debug:
    msg: "{{ item.members }} has name {{ item.name }} and state {{ item.state }}"
  with_items: "{{ bigip_device_facts.ltm_pools }}"
  when: item.full_path  == "/Common/mypool"

This doesn't work. It remains at member level. How can I reference the sublevel of members? Thanks!
