Setting up and managing event groups from the TrueSight console

To create an event group

1. Log on to the TrueSight console.
2. In the navigation pane, expand Monitoring and select Events. 
3. In the Events page, click the View event groups icon . 
4. In the Event Groups page, click the main action menu and select Create Event Group.
   
5. Specify a name for the event group.
6. Select a parent for the event group:
   1. Click Select Parent Group.  

   2. Navigate through the hierarchy of event groups and select the event group that you want to set as parent and click OK.

      Note

      By default, Event Groups is the root or topmost level of event group.

7. Specify the filtering criteria for the event group:

   1. From the Class list, select the type of event.
   2. 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.

   

   NoteFor 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.

   Comparison operators

   Operator	Description	Slot types
   ==	Events are listed only if the slot value matches the comparison value.	Enum, String, Number, List of String
   !=	Events are listed only if the slot value does not match the comparison value.	Enum, String, Number, List of String
   >	Events are listed only if the slot value is greater than the comparison value.	Enum, String, Number
   <	Events are listed only if the slot value is less than the comparison value.	Enum, String, Number
   >=	Events are listed only if the slot value is greater than or equal to the comparison value.	Enum, String, Number
   <=	Events are listed only if the slot value is less than or equal to the comparison value.	Enum, String, Number
   Has prefix	Events are listed only if the slot value starts with the comparison value.	String, Number
   Has suffix	Events are listed only if the slot value ends with the comparison value.	String, Number
   Contains	Events are listed only if the slot value contains the comparison value.	String, Number, List of String
   Within	Events are listed only if the slot value is an exact match with one of the comma-separated list of comparison values.	String, Number
   Contains one of	Events are listed only if the slot value is an exact match with one of the comma-separated list of comparison values.	String, Number
   Outside	Events are listed only if the slot value does not match with any of the comma-separated list of comparison values.	String, Number
   Matches	Events are listed only if the slot value contains the comparison value. You can provide the following parameters in addition to the comparison value: %d - decimal integer number %f - floating point real number %c - single character %s - string value Consider the following example values in the message slot of eight events: Event 1 Memory Consumption - 10 MB – on machine clm-dev-008700 Event 2 CPU utilization 85.35% – on machine clm-dev-007890 Event 3 Memory Consumption - 5 MB – on machine clm-dev-108781 Event 4 CPU utilization 75.95% – on machine clm-dev-087654 Event 5 Memory Consumption – 894  MB – on machine clm-dev-54657 Event 6 CPU utilization 68.45% – on machine clm-dev-37878 Event 7 Consumption of storage space is high on vm-dev-45 machine Event 8 Utilization taking higher trend When you use the matches operator for the message slot: Message matches Consumption – %d Events 1, 3, and 5 are displayed, as the following criteria matches: Consumption as a constant and an integer variable listed after Consumption. Message matches machine %s Events 1, 2, 3, 4, 5, and 6 are displayed as the following criteria matches: machine as a constant and a string variable listed after machine.	String, List of String
   Subclass of	Events are listed only if they are a subclass or child class of the provided class.	Class
   Superclass of	Events are listed only if they are a super-class or parent class of the provided class.	Class

   Note

   • The search is not case sensitive, except for the List of String slot type. For example, an event with slot value "London" is listed when you specify "london" or "London" for an "==" operator.
   • For operations on strings like ">" or "<", the ASCII values of strings are used for comparison.
     For example, if you use the operator ">" when the Message slot has “cell started” and the comparison string is “b”, this event is listed. If the comparison string is “d”, this event is not listed.
   • The slot type number includes integers, floating point, and real numbers.

8. 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.
