If Activity Monitor app (network, disk) and top don't get you where you 
want here, then iostat and fs_usage might be useful analogs. See man 
for details.
Other potential add-on options for monitoring macOS and some other 
platforms are Glances (https://github.com/nicolargo/glances) and htop.
Xcode Instruments is built atop DTrace framework, if you wanted to go 
that way. With Xcode installed, launch Instruments and select Activity 
Monitor, or such.
