| 40 |
system information. |

<title>Coloured Output</title> |
| 87 |
<para> |
| 88 |
When the <option>-c</option> option is used saidar uses colours |
| 89 |
to display the data. Each area has a different colour to |
| 90 |
distinguish it from the nearby fields. Bold and reverse video |
| 91 |
effects are used to emphasis fields where necessary. |
| 92 |
</para> |
| 93 |
<para> |
| 94 |
The load average figures are displayed in bold when they're |
| 95 |
notably (greater that 1) different to each other. This purely |
| 96 |
shows that a change in the load is occuring. |
| 97 |
</para> |
| 98 |
<para> |
| 99 |
When CPU usage goes over 60% it will be displayed in bold. |
| 100 |
At 90% the field is displayed using reverse video. Likewise |
| 101 |
for memory, swap and disk usage at 75% and 90%. Zombie |
| 102 |
processes are also highlighted. |
| 103 |
</para> |
| 104 |
<para> |
| 105 |
Other values (paging, disk I/O and network I/O) are not |
| 106 |
highlighted due to the nature of the values; it's not easy |
| 107 |
to determine what thresholds are significant. |
