I have an application that uses enough memory (Gigabytes) that it sometimes slows way down because of swapping. I'd like to be able to tell the user when that happens, so the user will not give up in disgust. My application is threaded, and the swapping generally takes place in one particular thread, so I could in principle have another thread monitor and report. But I am not familiar enough with low-level Unix memory-management stuff to know whether there is any way to track what is going on, or even where to start to look.

Can anyone offer advice or suggestions?

See the man page for getrusage. There are very likely ways that you can reduce swapping in your application. You should look into that first.
