In the trigger overview widget, you can display the trigger states for a group of hosts.
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.
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.
To configure, select Trigger overview as type:
In addition to the parameters that are common for all widgets, you may set the following specific options:
|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
|Host groups||Select the host group(s). This field is auto-complete so starting to type the name of a group will offer a dropdown of matching groups.|
|Hosts||Select hosts. This field is auto-complete so starting to type the name of a host will offer a dropdown of matching hosts. Scroll down to select. Click on 'x' to remove the selected.|
|Tags||Specify tags to limit the number of item and trigger 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 host location - left or top.|
