swapusage
About
This little utility for Linux shows the amount of swapped memory for running processes.
Contrary to popular belief this is actually not that easy, and tools like
top either don't do this at all, or completely wrong; see
this discussion on StackOverflow for some background.
After finding some of the proposed scripts unacceptably inefficient, I decided to write my own in C++.
Requirements
- Compiler with C++14 support
- Linux :)
Installation
- Type "make" & copy the executable wherever you want.
- If you encounter any problems then please fix them and send a pull request. :)
Gentoo users can find an ebuild in my overlay.
Usage
$./swapusage -h

More information
While swapusage is a good first step towards analyzing a swap (and memory) situation, you might find that you need much more detailed analysis capabilities. In that case you could look at smem.
