Objective
To define an indication for the resource model and the aggregation settings
that determine when a sequence of indications produce an event.
Background information
When you define an event, you must specify the attributes that qualify
it. In particular, you must select the most significant attribute for the
aggregation process.
While defining an event, you can also indicate if you want the system to
notify the Tivoli Enterprise Console server and Tivoli Business Systems Manager that an event was generated. The IBM Tivoli Monitoring operator
can change these selections when the resource model is included in an IBM Tivoli Monitoring profile.
You can also define the degree of severity and the message that specifies
the notification of the event.
Before you begin
None
When you finish
Check the Tasks view to verify that you do not have any errors in your
resource model. If the Tasks view displays errors, correct the errors before
running the resource model. The Tasks view displays in the bottom pane of
the IBM Tivoli Monitoring Resource Model Builder.
Procedure
- Open the resource model.
- Select the Events page.
- Edit an existing event or click Add Event to add
a new event to the resource model.
Additional Information: Customize the following event options:
- Internal Name
- The internal name of an event must be unique within the entire set of
resource models installed on a specific IBM Tivoli Monitoring server. If two or more resource
models specify events with identical names, then you cannot install those
resource models on the same IBM Tivoli Monitoring server. Follow naming conventions and best
practices as described in Designing a resource model.
- Descriptive name
- The descriptive name of this event that is informative and recognizable
for logging and reporting information.
- Message
- The message the event sends to the Tivoli Enterprise Console server or Tivoli Business Systems Manager. When typing
the message, specify event attributes that are variables between "@" symbols.
For example: "This process @ProcessName@, @ProcessID@ is consuming too much CPU."
- Send to TBSM
- To send the event notification to the Tivoli Business Systems Manager server as a default.
- Send to TEC
- To send the event notification to the Tivoli Enterprise Console server as a default. When
you select Send to TEC the Default
Event Hierarchy check box displays.
- Default Event Hierarchy
- Clear this box to create event hierarchy in Tivoli Enterprise Console by specifying a parent
for this event in the Event Parent text box. By default,
this box is selected and the event parent is set to TMW_EVENT.
- Event Parent
- The parent of this event in the Tivoli Enterprise Console hierarchy. This enables you to
organize events into hierarchies that are understood by the Tivoli Enterprise Console. When the
resource model is saved, the parent is saved to the workspace XML file. By
default, the event parent is set to TMW_EVENT.
- Severity
- The degree of severity for notification to the Tivoli Enterprise Console server or Tivoli Business Systems Manager.
Make a selection from the drop-down list.
- Description
- The descriptive text that is displayed on the IBM Tivoli Monitoring windows and that
provides information for the operator running the resource model.
- Attributes
- Add or remove attributes from the event. Attributes detail an event
by enabling you to get as much information as you need from the event. For
example, an event might indicate that your disk subsystem has problems, but
by associating attributes such as, bytes per second, disk name, or available
disk space you can more easily identify the problem.
Do the following to
add an attribute:
- Click Add or right-click inside the table.
- Enter the name of the attribute in the Name column.
Note:
If you are going to enable logging for this resource model, use
the same names for attributes here and in the logging definitions when specifying
the same metric.
- Select the Type column and select the type from
the drop-down list.
- Select the Is Key column to make this the key attribute.
When selected, a check mark displays in this column. Key attributes are the
most meaningful and play a fundamental role in the event aggregation process.
Use the up and down arrow buttons to specify the order of the
attributes.
Click Remove to remove the selected
attribute from the event.
- Aggregation Settings
- The conditions under which this indication becomes an aggregated event.
Only aggregated events trigger actions, notify you of a problem, and send
notification to the Tivoli Enterprise Console and Tivoli Business Systems Manager.
- Clearing Event
- Select Clearing Event if you want the system to
send a clearing event when the circumstances that generated the event are
resolved.
The Tivoli Enterprise Console server and Tivoli Business Systems Manager use the clearing event to close the
corresponding error event.
For example, if the resource being monitored
is a service, the event is sent when the service is not available. The event
might have an action associated with it to restart the service (or the restart
might be done manually). When the engine detects that the service is available
again, a clearing event can be sent to close the original event.
- Number of occurrences
- The number of indications that must occur before an event generates.
The number of occurrences must be greater than zero. This is the default value
for this resource model. You can change this value at runtime in the IBM Tivoli Monitoring application.
- Number of holes
- The maximum number of monitoring cycles allowed with no indications
for an event to be generated. The number of holes must be greater than or
equal to zero. This is the default value for this resource model. The user
can change this value at runtime in the IBM Tivoli Monitoring application.
- (Optional) Click Action to
associate a recovery action with the event, as described in Adding Actions.
- Save the changes and close the resource model, or go to another editing
page.
