] [-c] [-v] [-h]
is a curses-based tool for viewing the system statistics available
through libstatgrab. Statistics include CPU, processes, load, memory, swap,
network I/O, disk I/O, and file system information.
The following options are supported.
- -d DELAY
- Wait DELAY seconds between updates (default 3)
- Enables coloured output
- Prints the version number
- Display help and exits

reverse video effects are used to emphasis fields where necessary.

that 1) different to each other. This purely shows that a change in the load
When CPU usage goes over 60% it will be displayed in bold. At 90% the field is
displayed using reverse video. Likewise for memory, swap and disk usage at 75%
and 90%. Zombie processes are also highlighted.
Other values (paging, disk I/O and network I/O) are not highlighted due to the
nature of the values; it's not easy to determine what thresholds are
