getting hardware information of all devices on the network

Question

I was wondering if i can get a full hardware information about each device on the network? (preferred linux commands) with the nmap command I found the devices in my net, but only name, ip addresses and MAC. is it possible to get full hardware info like CPU info, RAM info(size & freq of each card), PCIe cards are connected, Hard Disks, etc..

Answer 1

I would recommend you look at configuration management/provisioning tools such as ansible, puppet, chef.

Ansible is probably the easiest to configure in your environment in order to fulfill the data collection task you have.

Once configured, the setup module may cover what you need (http://docs.ansible.com/ansible/latest/setup_module.html):

# Display facts from all hosts and store them indexed by I(hostname) at C(/tmp/facts).
# ansible all -m setup --tree /tmp/facts
