# System Config Info

This tool is to collect the system information automatically on the tested GPU nodes including the following hardware categories:

- [System](#system)
- [Memory](#memory)
- [CPU](#cpu)
- [Disk](#disk)
- [Networking](#networking)
- [Accelerator](#accelerator)
- [PCIe](#pcie)

## Usage

### Usage on local machine

1. [Install SuperBench](../getting-started/installation.mdx) on the local machine using root privilege.

2. Start to collect the sys info using `sb node info --output-dir ${output-dir}` command using root privilege.

3. After the command finished, you can find the output system info json file `sys_info.json` of local node under \${output_dir}.

### Usage on multiple remote machines

1. [Install SuperBench](../getting-started/installation.mdx) on the local machine.

2. [Deploy SuperBench](../getting-started/run-superbench.md#deploy) onto the remote machines.

2. Prepare the host file of the tested GPU nodes using [Ansible Inventory](../getting-started/configuration.md#ansible-inventory) on the local machine.

3. After installing the Superbnech and the host file is ready, you can start to collect the sys info automatically using  `sb run --get-info` command. The detailed command can be found from [SuperBench CLI](../cli.md).

  ```
  sb run --get-info -f host.ini --output-dir ${output-dir} -C superbench.enable=none
  ```

4. After the command finished, you can find the output system info json file `sys_info.json` of each node under \${output_dir}/nodes/${node_name}.
