# Керівництво по Системному монітору

## Вступ

### Системний монітор

Shows System Monitor. Displays a graph for system CPU load.

The System Monitor displays system load information in graphical format in a panel. You can configure System Monitor to display the following information for your system:

- Usage of CPU (central processing unit) time

- Використання пам'яті

- Мережевий трафік

- Використання простору swap

- Average system load

- Disk load

### Щоб додати Системний монітор до панелі

Щоб додати Системний монітор до панелі, виконайте такі кроки:

1. Клацніть правою кнопкою миші на панелі.

2. Виберіть Додати до панелі.

3. Гортайте вниз перелік документів у діялоґовому вікні Додати до панелі й виберіть Системний монітор.

4. Натисніть Додати.

The layout of the System Monitor varies depending on the size and type of panel in which the applet resides.

## Viewing Graphs

### Displaying Additional Graphs

To configure the System Monitor applet, right-click on the applet, then choose Preferences. Under Monitored Resources you can choose which graphics you want to display:

- Процесор

  Select this option to display the graph for CPU usage.

- Пам'ять

  Select this option to display the graph for memory usage.

- Мережа

  Select this option to display the graph for network traffic.

- Swap Space

  Select this option to display the graph for swap-space usage.

- Load

  Select this option to display the graph for average system load.

- Жорсткий диск

  Select this option to display the graph for disk usage.

### To Display the Current Usage of a System Resource

To display the current usage of a system resource, position the mouse pointer over the corresponding graph in the applet. A tooltip displays the current usage as a percentage.

### To Display Additional System Monitor Information

To display additional system monitor information, right-click on the applet, then choose Open System Monitor to start the System Monitor application.

The System Monitor application enables you to monitor system processes and usage of system resources. You can use the System Monitor application to modify the behavior of your system.

## Customizing Appearance

### Діялоґове вікно параметрів

Preferences Dialog

### To Change the Width

In the right-click menu, go to Preferences. Under Options, use the System monitor width spin box to specify the width of each System Monitor graph in pixels.

### To Update at Regular Intervals

In the right-click menu, go to Preferences. Under Options, use the System monitor update interval spin box to specify the interval at which you want to update the graphs in milliseconds.

### Changing the Colors in a Graph

To change the colors in a graph, perform the following steps:

1. Right-click on the applet, then choose Preferences.

2. Select the relevant tab in the Colors area of the System Monitor Preferences dialog.

3. Click on the relevant color selector button in the selected tabbed section.

4. On the Pick a Color dialog, use the color wheel or spin boxes to choose the line color for the selected parameter.

5. Натисніть Так.

The tabbed section for each resource provides color selection buttons that you can use to change the color of the parameters for each resource.

  Idle | Unused processor capacity

- Пам'ять

  Select this tab to display the color buttons for the following parameters:

  Parameter | Опис

  Select this tab to display the color buttons for the following parameters:

  Parameter | Опис
  Used | Swap space being used by the system
  Free | Swap space that is free to be used

- Load

  Select this tab to display the color buttons for the following parameters:

  Parameter | Опис

  Тло | Idle disk time

### Межі швидкости мережі

Thresholds together with indicator allow network graph to scale and better represent actual workload. If combined network traffic (in + out + loopback) is below threshold1, no indicator is shown, y-axis on network graph go from 0 to threshold1. When traffic is more than threshold1, one indicator will be shown and y-axis now go from 0 to threshold2. When threshold2 is reached, two indicators will be shown and y-axis go from 0 to threshold3. When threshold3 is reached, three indicators are shown and y-axis go form 0 to whatever is current maximum in graph.

Gridlines are hard to explain, just observe, and they are obvious.
