3 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 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.

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/

Clicking on a piece of data offers links to some predefined graphs or latest values.
