saidar [-d delay] [-c] [-v] [-h]
saidar 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
When the -c option is used saidar uses colours to display the data. Each area has a different colour to distinguish it from the nearby fields. Bold and reverse video effects are used to emphasis fields where necessary.
The load average figures are displayed in bold when they're notably (greater that 1) different to each other. This purely shows that a change in the load is occurring.
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 significant.
