Hardwarespec is an easy way to describe server hardware in yaml and test that your specs match.

##Required Software Hardwarespec requires Ansible to be installed, and uses standard Ansible conventions to describe your servers and run the tests.

##Describing a server Servers can be described either individually or in groups. Settings for individual servers override the settings from any group they're in.

###Automatic spec generation You can automatically generate a hardware spec of an existing server by running the command below. Assuming your hosts are in your inventory file and you have SSH keys setup, run the checks with this command:

ansible-playbook -i inventory generate_spec.yml -u <user>

This generates a yaml configuration file for each server and automatically puts it in the 'host_vars' folder.

###Collecting variable statistics Using the generation script now collects the following variable information about your fleet. This information is not verified by the 'check' script:

cpu_performance
Ping
Download
Upload
cpu_utilization
security_patches

Some of this information requires additional tools to be installed. Hardwarespec provides an installer script to setup your hosts:

ansible-playbook -i inventory install_tools.yml -u <user>

####Describing groups of servers: Add a new group to your inventory file with the following syntax:

[group_name]
host_fqdn.example.com

Then create a file in the group_vars directory called group_name.yml (the name of file must match the name of the group in the inventory file)

Using yaml syntax, you can describe any or all of the following values. All variables are optional.

cpu_model
cpu_count
cores_per_cpu
total_memory_mb
total_swap_mb
virtualization_type
ipv4_addresses
ipv6_addresses
system_architecture
linux_distribution
distribution_version
fqdn
selinux_status

##Running the tests The tests are run through ansible using the check_hardware playbook. Assuming your hosts are in your inventory file and you have SSH keys setup, run the checks with this command:

ansible-playbook -i inventory check_hardware.yml -u <user>

If you only want to check a specific group (like 'dev') you can add the -l flag

ansible-playbook -i inventory check_hardware.yml -l dev -u <user>
