Hi Konstantinos,
WinCollect itself is an agent that you can download from IBM Fix Central or directly from here:
https://www.ibm.com/support/fixcentral/swg/selectFixes?parent=IBM%20Security&product=ibm/Other+software/IBM+Security+QRadar+SIEM&release=7.5.0&platform=Linux&function=textSearch&text=wincollect#WINCOLLECT
After downloading, you can install on Windows Server or PC to collect the Local Win Logs of that Server or PC
Another way is to use it to do remote collection of Win Logs from other Servers or PCs
You can choose between the Standalone flavour (Wincollect v7 or v10) or the Managed flavour (Wincollect v7 only)
Both support XPath to send advanced logs like Sysmon
BR,
