GKrellM is a GTK and Imlib-based stacked monitor program that charts SMP CPUs, disks, loads, active net interfaces and Internet connections.
Other monitors include:
- Memory and swap
- File system with a mount/umount feature
- Mailbox check
- A clock and a calendar
- APM laptop battery
- CPU temperatures and uptime
The program also has LEDs for the net monitors, and an on/off button and online timer for PPP.
There is a GUI pop-up for configuration, and GKrellM is themeable.
