15 Item card
Overview
The Item card widget provides comprehensive and customizable information about a single item.
The item can be set directly in the widget configuration or selected from a compatible widget on the dashboard.
The widget can display multiple sections, each showing different type of information (item description, latest data, etc.). Section layout automatically adjusts based on widget width. When expanded horizontally, sections are rearranged into multiple columns, ordered left to right across each row.
Configuration
To configure, select Item card as type:
In addition to the parameters that are common for all widgets, you may set the following specific options:
| Item | Select the item. Alternatively, select a compatible widget as the data source for items. Matching suggestions appear as you type. The top section of the widget always displays the item name (clicking it opens the item menu): - If the item is disabled, a red Disabled label is displayed next to the item name. - In case of errors, a square icon with the letter "i" is displayed. In case of problems, a square icon with the problem count is displayed for each problem severity. Hovering over an icon opens a pop-up with details. - On a template dashboard, the technical name (instead of visible name) of the item is displayed. The top section of the widget also displays the item path—its host and, if applicable, template, low-level discovery (LLD) rule, or master item (clicking an entity opens its configuration). Item path is displayed only to users with permissions to the respective entities. |
