Question

Network administration

Hello,
Can you please tell me the software solutions for managing a linux / unix server park to automate actions according to the example:
I want to get tail -10 /var/log/somelog or smartctl -d /dev/sda from all 100500 servers
Maybe someone there is experience and he can share it in the use of automation for the use of a fleet of servers.
