Monitor disk I/O with Cockpit


Log into Cockpit.

How to test

  1. Navigate to "Storage" for your machine.
  2. Copy some big files around on your machine, preferably from one disk to another. Maybe tar -cf /var/tmp/usr.tar /usr. (You might want to use the Cockpit Terminal for to execute commands like this.)
  3. Observe the graphs and the "Reading" and "Writing" numbers.
  4. Hover with your mouse over the graphs.

Expected Results

The page should show the ongoing data transfer. Hovering over a graph should highlight the corresponding disk.
