# Manual do Monitor do Sistema

## Introdução

### Monitor do sistema

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

- Uso de memória

- Tráfego da rede

- Uso do swap

- Average system load

- Disk load

### To Add System Monitor to a Panel

To add System Monitor to a panel, perform the following steps:

1. Clique com o botão direito no painel.

2. Escolha Adicionar ao Painel.

3. Scroll down the list of items in the Add to Panel dialog, then select System Monitor.

4. Click Adicionar.

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:

- Processor

  Selecione esta opção para exibir o gráfico do uso da CPU.

- Memoria

  Selecione essa opção para exibir o gráfico de uso da memória.

- Network

  Selecione esta opção para exibir o gráfico do tráfego de rede.

- Swap Space

  Selecione esta opção para exibir o gráfico do uso do swap.

- Load

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

- Harddisk

  Selecione esta opção para exibir o gráfico do uso do disco.

### 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

### Preferências

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.

### Alterando as cores em um gráfico

Para alterar as cores em um gráfico, execute as seguintes etapas:

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. Clique OK.

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

### Limiares de velocidade da rede

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 from 0 to whatever is current maximum in graph.

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