Is mongoreplay included in the toolset with mongodb 4.0 community version for windows?
mongoreplay is currently not included in the Windows installation packages (as at MongoDB 4.0). This tool uses the libpcap packet capture library which is available on most UNIX/Linux platforms but is not standard on Windows.

There's a relevant feature request to watch/upvote in the MongoDB Jira issue tracker: TOOLS-1730: Release  mongoreplay for windows.

I also raised DOCS-12355 as this should be more clearly noted in the documentation.
