Deze sectie geeft details weer van parameters die gemeenschappelijk zijn voor dashboard widgets.
De volgende parameters zijn gemeenschappelijk voor elke widget:
Naam | Voer een widgetnaam in. |
Vernieuwingsinterval | Configureer het standaard vernieuwingsinterval. Standaard vernieuwingsintervallen voor widgets variëren van Geen vernieuwing tot 15 minuten, afhankelijk van het type widget. Bijvoorbeeld: Geen vernieuwing voor URL-widget, 1 minuut voor actielog-widget, 15 minuten voor klok-widget. |
Toon koptekst | Markeer het selectievakje om de koptekst permanent weer te geven. Als het niet is aangevinkt, wordt de koptekst verborgen om ruimte te besparen en wordt deze alleen zichtbaar als de muis zich boven de widget bevindt, zowel in de weergave- als bewerkingsmodus. Het is ook gedeeltelijk zichtbaar bij het slepen van een widget naar een nieuwe positie. |
Vernieuwingsintervallen voor een widget kunnen worden ingesteld op een standaardwaarde voor alle overeenkomstige gebruikers, en elke gebruiker kan ook zijn eigen vernieuwingsinterval instellen:
Een uniek vernieuwingsinterval ingesteld door een gebruiker heeft prioriteit boven de widgetinstelling en zodra het is ingesteld, wordt het altijd behouden wanneer de instelling van de widget wordt gewijzigd.
Om specifieke parameters voor elke widget te zien, ga naar individuele widgetpagina's voor:
Multiple widgets have parameters that enable them to share configuration data between other widgets or the dashboard.
The Host groups, Hosts, Item, and Item list parameters allow selecting either the respective entities or a data source containing either host groups, hosts or items for which the widget can display data.
For Host groups, Item, and Item list parameters, the data source can be a compatible widget from the same dashboard.
For Hosts parameter, the data source can be a compatible widget from the same dashboard or the dashboard itself.
The Map widget can also broadcast host group and host data to compatible widgets. For more information, see Widget behavior.
The Override host parameter allows selecting a data source containing a host for which the widget can display data. The data source can be a compatible widget from the same dashboard or the dashboard itself.
To specify a compatible widget, enter its name and select it. Alternatively, click the Select button (or the dropdown button, then "Widget") to open a pop-up of available widgets.
To specify a dashboard, click the dropdown button, then "Dashboard". After saving the dashboard, the Host field (for selecting hosts) will appear at the top of the dashboard.
The Time period parameter allows selecting a data source containing a time period for which the widget can display data. The data source can be a compatible widget from the same dashboard, the dashboard itself, or the time period configured on the widget itself.
To specify a compatible widget, set Time period to "Widget", enter its name and select it. Alternatively, click the Select button to open a pop-up of available widgets.
To specify a dashboard, set Time period to "Dashboard". After saving the dashboard, the Time period selector will appear at the top of the dashboard.
To configure the time period on the widget itself, set Time period to "Custom" and enter or select the start and end of the time period.
Regardless of the widget's Time period configuration, compatible widgets can use it as a data source for the time period.
Some widgets can broadcast configuration data to other widgets, some can listen for data, and some can do both. For example:
The following table outlines the broadcasting and listening capabilities of each widget.

Widgets differ in how they broadcast data to other widgets.
All widgets capable of broadcasting data begin doing so automatically upon creation. For example, the Graph widget immediately broadcasts time period data to listening widgets.
Widgets supporting entity selection (e.g., Item navigator) automatically broadcast data for the first available entity. For example, the Item navigator widget broadcasts data for the first item in its item list. When a different item is selected, it broadcasts data for that item. On mouseover, the item is highlighted in light blue color; on selection, it is highlighted in yellow color.
The Map widget also automatically broadcasts data for the first available element (e.g., host), which is closest to the top-left corner of the widget's viewport (for Geomap widget, closest to the center of the widget's viewport). When a different element is selected, it broadcasts data for that element. On mouseover, the element is highlighted in light blue color; on selection, it is highlighted in dark blue color.
Widgets also have specific behaviors when listening for data from other widgets:
