Hi @Srinivasu Jogi ,
As per my knowldege, we cannot filter the SharePoint logs in Azure Activity log as Activity log only provides insight into subscription-level events. If you want to trace user activity in SharePoint Online, you need to Search the audit log in the compliance center. As to the the SIEM tool, we don't provide support for 3rd party software on Micorosft Q&A currently, I would suggest you contact 3rd party support.
