How do I configure IBM Power Linux SSH monitoring?

Supported devices

To create a monitoring user account

Configuration details to specify when adding the asset to Entuity

Entuity supports hardware monitoring on IBM Power Systems running Linux operating systems (OSes) through SSH commands. Entuity discovers the enclosure, SAS enclosures, power supplies and fans, processors, disk controllers, memory modules, network interfaces, ports, and physical disks of each system. To do so, the Entuity collector uses port 22 (which must be open bidirectionally between the Entuity server/agent and the IBM Power System) and a monitoring user account. 

Supported devices

• IBM Power Systems running the Linux OS

To create a monitoring user account:

Prerequisite: 

Sudo must be installed on the system before you can create a monitoring user account.

Note, the italicized text in the code examples of this procedure represent variables. Replace the variables in the examples with values that are applicable to your environment. 

1. As root, create a new user account on the system.
   Note, the start of the username and password can't include any special characters that are used by Linux commands, such as exclamation points.

   # useradd -m <username>
   
   

2. Create a password for the new user. 

   # passwd <username> 
   
   

3. Enter and confirm the password.
4. Ensure that the newly created user account has permissions to run SSH commands, such as lscfg, lsblk, and servicelog.
