3 Data overview
This widget is deprecated and will be removed in the upcoming major release. Consider using the Top hosts widget instead.
Overview
In the data overview widget, you can display the latest data for a group of hosts.
The color of problem items is based on the problem severity color, which can be adjusted in the problem update screen.
By default, only values that fall within the last 24 hours are displayed. This limit has been introduced with the aim of improving initial loading times for large pages of latest data. This limit is configurable in Administration → General → GUI, using the Max history display period option.
Clicking on a piece of data offers links to some predefined graphs or latest values.
Note that 50 records are displayed by default (configurable in Administration → General → GUI, using the Max number of columns and rows in overview tables option). If more records exist than are configured to display, a message is displayed at the bottom of the table, asking to provide more specific filtering criteria. There is no pagination. Note that this limit is applied first, before any further filtering of data, for example, by tags.
Configuration
To configure, select Data overview as type:
In addition to the parameters that are common for all widgets, you may set the following specific options:
| Host groups | Select host groups. Alternatively, select a compatible widget as the data source for host groups. This field is auto-complete so starting to type the name of a group will offer a dropdown of matching groups. This parameter is not available when configuring the widget on a template dashboard. |
| Hosts | Select hosts. Alternatively, select a compatible widget or the dashboard as the data source for hosts. This field is auto-complete so starting to type the name of a host will offer a dropdown of matching hosts. This parameter is not available when configuring the widget on a template dashboard. |
| Item tags | Specify tags to limit the number of item data displayed in the widget. It is possible to include as well as exclude specific tags and tag values. Several conditions can be set. Tag name matching is always case-sensitive. There are several operators available for each condition: Exists - include the specified tag names; Equals - include the specified tag names and values (case-sensitive); Contains - include the specified tag names where the tag values contain the entered string (substring match, case-insensitive); Does not exist - exclude the specified tag names; Does not equal - exclude the specified tag names and values (case-sensitive); Does not contain - exclude the specified tag names where the tag values contain the entered string (substring match, case-insensitive). There are two calculation types for conditions: And/Or - all conditions must be met, conditions having the same tag name will be grouped by the Or condition; Or - enough if one condition is met. |
| Show suppressed problems | Mark the checkbox to display problems that would otherwise be suppressed (not shown) because of host maintenance. |
| Hosts location | Select hosts location - left or top. This parameter is labeled Host location when configuring the widget on a template dashboard. |
