About iotop-c
iotop-c is a C implementation of iotop. Where iostat can tell you which disk is slow, iotop-c shows which processes are reading and writing, so you can find the cause of high I/O wait on a slow or heavily loaded machine.
It runs in the terminal with a top-style display and suits Linux server administrators and desktop users tracking down disk activity.
Strengths
- Shows disk I/O per process rather than per device
- Familiar top-style terminal display
- Packaging files included for Debian and Fedora
Limitations
- Linux only
- Usually needs root privileges to see all processes
