Issue/Introduction

If you need to get or find or check CPU information from the command line, this is how you can do it on a Security Analytics appliance.

Resolution

The command-line utility “lscpu” in Linux is used to get CPU information of the system. The “lscpu” command fetches the CPU architecture information from the “sysfs” and /proc/cpuinfo files and displays it in a terminal.

1. Login to SA command line with root credentials.
2. Enter command:  lscpu
