Objective
To specify when you want an event to generate and whether you want it sent
to the Tivoli Enterprise Console server or Tivoli Business Systems Manager.
Background information
Only events can notify that there is a problem in the resource state, trigger
an action and, if enabled, send a notification to the Tivoli Enterprise Console server or to the Tivoli Business Systems Manager.
Before you begin
Select one or more properties from the monitored properties and specify
the conditions that must be satisfied to generate an event. For more information
about events, see Events and indications.
When you finish
After creating a trigger condition, the datasource displays the triggers
below it. You can remove a trigger by right-clicking on it. Double-clicking
opens the trigger for editing. Right-clicking on the selected datasource allows
that datasource to be deleted along with all triggers created with it.
You have the option to select properties to log, as described in Selecting the properties to log. You can also add another CIM, monitoring collection,
or custom script datasource. Then, specify the resource model cycle time as
described in Entering a cycle time.
Procedure
- Double-click a property to open the Event Triggering Condition window.
- Select one of the following logical operators from the drop-down list:
Numeric property options:
- >
- Records the value of the selected property, compares it to the value
you specify in the text box, and triggers an event if the current value is
greater than the specified value.
- <
- Records the value of the selected property, compares it to the value
you specify in the text box, and triggers an event if the current value is
less than the specified value.
- =
- Records the value of the selected property, compares it to the value
you specify in the text box, and triggers an event if the current value is
equal to the specified value.
- <>
- Records the value of the selected property, compares it to the value
you specify in the text box, and triggers if the current value is not equal
to the specified value.
- >=
- Records the value of the selected property, compares it to the value
you specify in the text box and triggers an event if the current value is
larger than or equal to the specified value.
- <=
- Records the value of the selected property, compares it to the value
you specify in the text box and triggers an event if the current value is
smaller than or equal to the specified value.
- Increases at least by
- Checks the current value of the selected property against the previous
value and triggers an event if the current value is greater than the previous
one by a value equal to or greater than the value you specify in the text
box.
- % increases at least by
- Checks the current value of the selected property as a percentage of
the previous value and triggers an event if current value is greater than
the previous one by a value equal to or greater than the value you specify
in the text box.
- Decreases at least by
- Checks the current value of the selected property against the previous
value and triggers an event if the current value is smaller than the previous
one by a value equal to or greater than the value you specify in the text
box.
- % decreases at least by
- Checks the current value of the selected property as a percentage of
the previous value and triggers an event if current value is smaller than
the previous one by a value equal to or greater than the value you specify
in the text box.
- Changes by
- Compares the previous and current values of the selected property and
triggers an event if between these two values there is a difference equal
to the value you specify in the text box.
- Changes at least by
- Compares the previous and current values of the selected property and
triggers an event if between these two values there is a difference equal
to or greater than the value you specify in the text box.
- Is out of the range
- Compares the current value of the selected property against the defined
range limits, and triggers an event if the current value falls outside the
specified range.
String property options:
- Is equal to
- Records the value of the selected property, compares it to the value
you specify in the text box, and triggers an event if the current value is
equal to the specified value.
- Is not equal to
- Records the value of the selected property, compares it to the value
you specify in the text box, and triggers an event if the current value is
different from the specified value.
- Contains
- Records the value of the selected property, compares it to the value
you specify in the text box, and triggers an event if the current value contains
the specified value.
- Enter a string or numeric value in the text box next to the drop-down
list.
Additional Information: Specifying the logical
operator and value builds the logical expression.
- Enter the number of occurrences of the specified condition that must be
detected before the resource model generates an event.
Note:
The
number of occurrences must be greater than zero.
- Enter the number of holes allowed before the resource model generates
an event.
Note:
The number of holes must be greater than, or equal
to, zero.
- Select the Event severity from the drop-down list.
- (Optional) Select the first check box if you want
an event to generate when the conditions that had previously caused an event
get resolved.
- (Optional) Select the remaining two check boxes
if you want to send this event to the Tivoli Enterprise Console server or Tivoli Business Systems Manager.
- Click OK to return to Specify the Event Triggering
Conditions window.
- (Optional) Repeat this procedure for each event
you want to generate.
- Click Next to proceed with the wizard.
