Visão geral de triggers
A imagem a seguir apresenta exemplo da visão geral das triggers. São apresentados os estados das triggers (representado por suas cores) em cada host ao qual elas estão associadas:
Observe que as triggers que tiveram modificações recentes (nos últimos 30 minutos) serão apresentadas como blocos piscantes.
Setas para cima e para baixo indicam que a trigger tem dependências, ao passar com o mouse por cima delas as dependências são apresentadas.
Ao clicar em um bloco de trigger é apresentado o menu flutuante de triggers com links relacionados.
Visão geral de dados
A imagem a seguir apresenta exemplo da visão geral de dados. São apresentados os dados de Performance (observe o filtro) de dois hosts.
Apenas dados obtidos nas últimas 24 horas são apresentados por padrão, este limite foi introduzido para evitar problemas de performance ao buscar dados muito antigos. É possível modificar esta limitação ao modificar a constante ZBX_HISTORY_PERIOD no arquivo include/defines.inc.php.
Clicando em um dado será apresentado um menu flutuante com links para gráficos pré-definidos ou dados recentes.
Overview
The Monitoring → Overview section offers an overview of trigger states or a comparison of data for various hosts at once.
The following display options are available:
- select all hosts or specific host groups in the Group dropdown
- choose what type of information to display (triggers or data) in the Type dropdown
- select horizontal or vertical display of information in the Hosts location dropdown
Overview of triggers
In the next screenshot Triggers are selected in the Type dropdown. As a result, trigger states of two local hosts are displayed as coloured blocks (the color of problem triggers depends on the problem severity color, which can be adjusted in the problem update screen):
Note that recent trigger changes (within the last 2 minutes) will be displayed as blinking blocks.
Blue up and down arrows indicate triggers that have dependencies. On mouseover, dependency details are revealed.
A checkbox icon indicates acknowledged problems. All problems or resolved problems of the trigger must be acknowledged for this icon to be displayed. (Before 4.0.14 it was enough for the last problem to be acknowledged.)
Clicking on a trigger block provides context-dependent links to problem events of the trigger, the problem acknowledgment screen, trigger configuration, trigger URL or a simple graph/latest values list.
Buttons
Buttons to the right offer the following options:
 |
Display page in fullscreen mode. |
 |
Display page in kiosk mode. In this mode only page content displayed. The kiosk mode button appears when the fullscreen mode is activated. To exit kiosk mode, move the mouse cursor until the  exit button appears and click on it. Note that you will be taken back to normal mode (not fullscreen mode). |
 |
Additional information on the page content is displayed if you roll the mouse over this button. |

You can use the filter to display only the problems you are interested in. The filter is located above the table.
| Parameter | Description |
|---|---|
| Show | Filter by problem status: Recent problems - unresolved and recently resolved problems are displayed (default) Problems - unresolved problems are displayed Any - history of all events is displayed |
| Acknowledge status | Filter by acknowledgment status: Any - acknowledged and unacknowledged problems are displayed (default) With unacknowledged events - problems with unacknowledged events are displayed With last event unacknowledged - problems with last event unacknowledged are displayed |

Overview of data
In the next screenshot Data is selected in the Type dropdown. As a result, performance item data of two local hosts are displayed.
The color of problem items is based on the problem severity color, which can be adjusted in the problem update screen.
Only values that fall within the last 24 hours are displayed by default. This limit has been introduced with the aim of improving initial loading times for large pages of latest data. It is also possible to change this limitation by changing the value of ZBX_HISTORY_PERIOD constant in include/defines.inc.php.
Clicking on a piece of data offers links to some predefined graphs or latest values.
