Creating event groups
Best practice
- To mitigate performance impact, observe the following guidelines:
- Do not create more than five levels in an event group hierarchy.
- At any hierarchical level, create a maximum of 25 event groups.
- Ensure that the total number of event groups is equal to or less than 50.
- When creating an event group, avoid complex pattern-matching conditions on slot contents and use narrowly-defined classes rather than complex Where clauses.
To create an event group
The following video (3:16) explains how to create an event group.

Perform the following actions to create an event group:
- Log on to the TrueSight console.
- In the navigation pane, expand Monitoring and select Events.
- In the Events page, click the View event groups icon .
- In the Event Groups page, click the main action menu and select Create Event Group.
- Specify a name for the event group.
- Select a parent for the event group. By default, Event Groups is the root or topmost level of event group.
Click Select Parent Group.
Navigate through the hierarchy of event groups and select the event group that you want to set as parent and click OK.
Select the Table View if you want to associate the table view with this event group. By default, the Basic Information table view is associated.
Note
User defined table views cannot be associated with the event groups.
- Specify the filtering criteria for the event group:
- From the Class list, select the type of event.
- Select the event attributes and comparison operators that are listed in Slots.
Note
Filtering criteria that are associated with the parent event group are already applied to the child event group. The inherited criteria is displayed in gray color.
Note
For some event attributes, the internal names are displayed. For example,
error_message, error_val
.If you want to view the display name for an event attribute, you need to add the attribute to the en.json file:
1. Open the en.json file from the <installationDirectory>\TrueSightPServer\truesightpserver\modules\tomcat\webapps\infraApp\WEB-INF\classes folder.
2. Go to the end of the file and add a comma after the last line of code and press ENTER.
3. Add information for the event attribute in the following format:
eventView.slot.<CLASS_NAME>.<SLOT_NAME>=<SLOT_DISPLAY_NAME>
where,CLASS_NAME =
Event class name of your event attribute (slot)SLOT_NAME =
Internal name of the event attribute that is currently displayedSLOT_DISPLAY_NAME =
Name of the event attribute that you want to replace the internal name with4. Repeat the earlier step for all the event attributes that you want to add.
5. Restart the Presentation Server.
For more information about event classes and slots, see How event classes are structured . Click OK.
If you select the topmost level of the event groups, Event Groups, as a parent, it is displayed as [None] in the event group's tile.
