Next Steps

1. Test the role on a sample host:

   ansible-playbook playbooks/gather_system_info.yml -l localhost
   

2. Verify output files:

   ls -la ./stats/machines/$(hostname -f)/
   cat ./stats/machines/$(hostname -f)/summary.txt
   jq . ./stats/machines/$(hostname -f)/system_info.json
   

3. Run validation:

   ansible-playbook playbooks/gather_system_info.yml -t system_info,validate
   

4. Test selective gathering:

   ansible-playbook playbooks/gather_system_info.yml -t system_info,cpu,memory
   

5. Review and customize variables in defaults/main.yml if needed

6. Integrate with your inventory and run across infrastructure
