There are a lot of tools out there a dba needs, and dbatools makes it easy to deploy and update the most popular solutions across the entire estate:

Get-DbaRegisteredServer -SqlInstance cms | Install-DbaFirstResponderKit
Get-DbaRegisteredServer -SqlInstance cms | Install-DbaMaintenanceSolution
Get-DbaRegisteredServer -SqlInstance cms | Install-DbaWhoIsActive

These lines will retrieve all registered instances and update the most relevant dba diagnostics tools on each of them.

All these maintenance and diagnostic tools can also be executed from within dbatools, to allow for easy automation of these SQL-native toolkits.
