Serial Number on Linux Server with ACC

[SK Chand Basha]

Hello Everyone!

The serial number is not being populated with agent client collector,  I’ve installed dmidecode using the following commands in amazon linux 2023

sudo yum install dmidecode

sudo dmidecode -s system-serial-number

Do we need to configure any permissions after the dmicode installation?

@SK Chand Basha: to retrieve the serial number on a Linux system, you need root or sudo privileges. ACC does use dmidecode to extract the serial number, so you need to add dmidecode to sudo for the user running the agent. See the ACC installation documentation for more details.

To retrive the serial number we have to add the servicenow user to sudoers file. 

Command : sudo visudo -f /etc/sudoers.d/servicenow

After run the above command file will be opened

Command : servicenow ALL=(ALL) NOPASSWD: /usr/sbin/dmidecode, /usr/sbin/ss

After entering the command, check the bottom to view the shortcuts.

First exit and it will ask to save the file Press Y and hit Enter

 . Log In as the User: After ensuring the user exists and is properly configured, you can switch to the user:

Command : sudo su - servicenow

Expected Result : Empty value

Command : sudo /usr/sbin/dmidecode

Here we can see Serial number

Restart the Mid server and ACC Service  

Command : systemctl list-unit-files --type service -all

Expected Result:

Shows List of services

Command : sudo systemctl restart (type_Servicename)
