Check SWAP in htop

#dev #til #tech

I struggle with maxxing swap on all my machines, I am sure it's a neovim config that I've propagated everywhere and I'm too lazy to figure it out. Instead I just swapoff and swapon kind of often... but this morning I had to know how to see what's using all that swap....

The way to see SWAP usage by process in htop is:

  1. open htop
  2. Slam F2 (f if you're just in old school top)
  3. see the screenshot, find M_SWAP
  4. move M_SWAP to Active Columns
