Hello! so I'm trying to do the following:

Retrieve Linux servers logs and filter them for specific events and then pass them to a SIEM solution.

Can I achieve that on the Log Stash level?  
And do I need all three layers of the stack? or can i just use Log Stash for this?

And my setup plan is as follows:

Have 3 nodes:  
Server 1: install Log Stash: 8 Core CPU, 64GB RAM, 140GB SSD  
Server 2: install Elastic Search: 8 Core CPU, 64GB RAM, 140GB SSD  
Server 3: install Kibana: 8 Core CPU, 8GB RAM, 140GB SSD

What do you think of the specs and architecture?  
All suggestions and pointers are appreciated.

Probably, but it depends on the details of how you obtain the logs and how you pass them to the SIEM system.

Without knowing anything about the volumes of logs you need to process?
