I’m tasked with creating an ansible playbook that will generate an inventory our our VCenter. I need to be able to get the stats like available and used CPU, available and used memory, available and used disk as well as a count of active VMs in each of my clusters.
I’ve been able to create a playbook using the community.vmware.vmware_cluster_info module that gets CPU, Memory, and Disk information, and I see it can give me a list of the ESXI Hosts in the cluster, but where I’m running into a wall is getting a count of active vms in each cluster, the cluster information module doesn’t seem to provide that. I see that there are a number of vmware_vm_* modules but all of those appear to get information about an individual vm. Since my need is a count of vms something that provides that would be the best solution, but I could do my own count if I can get a list of powered on vms in a cluster, or even a list of all vms in a cluster provided the list also gives me that state of the vm.
On a related topic, I see that community.vmware.vmware_cluster_info module allows you to define the exact properties you want it to return, what baffles me is where do I find a list of the property names? When I call the module under resource_summary I can see that CPU info is provided by cpuCapacityMHz but that to call that in properties the examples shows summary.totalCpu as the property to call. I was able to get what resource_summary calls memCapacityMB with summary.totalMemory following the example of totalCpu, but guessing at the other ones doesn’t result in the same mapping. So, how do I find out what the properties are called? The basic stats are available in the verbose output but that provides more than I’m looking for so if I can tailor my playbook for just the stats I want would be preferred.
Thanks for the response, I create a playbook based on your recommendation:
- hosts: localhost
gather_facts: false
collections:
- community.vmare
pre_tasks:
- include_vars: vars.yml
tasks:
- name: collect a list of the datacenters
community.vmware.vmware_cluster_info:
hostname: "{{ vcenter_hostname }}"
username: "{{ generic_auth_username }}"
password: "{{ ansible_awx_user_pw }}"
validate_certs: no
cluster_name: Perf
show_tag: true
delegate_to: localhost
register: cluster_info
- name: print it out to terminal
ansible.builtin.debug:
var: cluster_info
The above is similar to a running playbook that I have which gets inventory, my variables match what’s in my var file. When I run it I get the following error which looks like I have a broken module, is that correct and if so how do I fix?
The full traceback is:

Sorry about the formatting, I’m no more familiar with the editor on this forum than I am with Ansible, I copied and pasted what was on the screen and the editor changed it, put dots where hyphens were and changed all the indenting.
