Centralize log collector [on hold]

I would like to build a centralize log collector for my project which enables me to collect logs from network, AD, web proxy and etc. After collecting I will send them to any SIEM for analysis.

For the log collector, how do I do that without installing too many agents in individual PC

The PC with windows and linux OS running and using SNMP devices

More information:

For example, I am putting this collector at my friend-A home and another one at friend-B home. So all their network log, AD log, and workstation log will be collected by this collector and then the collector will send all the logs to be for monitoring and analysis.

Is there such a way to build a collector that can do the above requirement?

Thank you :)
