UsageMonitor vs Process

[nikko]

are there any (dis)advantages between UsageMonitor plugin and new internal Process measure when used for processes?

I think you entirely mixed up what Process and UsageMonitor do.
Anyways it depends on your use really, if you wanna retrieve how much a certain .exe is using, just use UsageMonitor, if you only want to retrieve if a process is running or not, use Process. Really depends what you use it for.
Obviously Process seems more lightweight, so if you wanna know if an .exe is running or not, just use that.
