Resource Properties Notebook: Aggregation Page
The Aggregation page displays the total number of real resources contained in the selected aggregate, as well as the current aggregation threshold values for the resource. For example, the number of resources in the aggregate that have to be in an exception state, such as unsatisfactory, before the aggregate becomes degraded could be displayed.
Note: This page is available only when the selected resource is an aggregate.
The Aggregation page displays the following information:
- Degraded
- The number, or
percentage,
of real resources in the aggregate that must be reporting an exception state to cause the status of this aggregate to become degraded. This number is expressed as either a count of resources or a percentage of resources as specified by the
Express as percentage box.
- minimum..maximum display
- The first set of numbers following the Degraded threshold field represents the current minimum and maximum values to which the Degraded threshold field can be set. These values can be either actual counts of resources or percentages of resources if the Express as percentage box is checked. If they are percentages, the values will be followed by a % (percent sign).
**
- [initial, default] display
- The second set of numbers following the Degraded threshold field represents:
- initial
- the value of the degraded threshold when the resource properties were initially retrieved.
- default
- the default value of the threshold from the resource type object in RODM. (This default value applies only to resources defined in RODM.)
These values can be either actual counts of resources or percentages of resources if the Express as percentage box was checked. If they are percentages, the values will be followed by a % (percent sign).
- Express as percentage check box
- If selected, the numbers in the Degraded threshold field, the minimum..maximum, and the [initial, default] are
percentages of resources, not counts of resources.
You can change the degraded threshold as follows:
- Specify a number less than or equal to the current maximum displayed to the right of the Degraded threshold field.
- Specify 0 to indicate that the aggregate resource always has a degraded status unless the severely degraded or unsatisfactory thresholds have been reached.
- Specify -1 to indicate that this resource never reports a degraded status unless the aggregation priority of a child resource causes the aggregate to display a degraded status.
- Specify -2 to indicate that the resource uses the resource type default threshold value of default displayed to the right of the Degraded threshold field. This setting is available only for resources defined in RODM.
- Severely Degraded
- The number, or
percentage, of real resources that must be reporting an exception state to cause the status of this aggregate to become severely degraded. This number is expressed as either a count of resources or a percentage of resources, as specified by the
Express as percentage box.
- minimum..maximum display
- The first set of numbers following the Severely degraded threshold field represents the current minimum and maximum values to which the Severely degraded threshold field can be set. These values can be either actual counts of resources or percentages of resources if the Express as percentage box is checked. If they are percentages, the values will be followed by a % (percent sign).
**
- [initial, default] display
- The second set of numbers following the Severely degraded threshold field represents:
- initial
- the value of the (severely degraded) threshold when the resource properties were initially retrieved.
- default
- the default value of the threshold from the resource type object in RODM. (This default value applies only to resources defined in RODM.)
These values can be either actual counts of resources or percentages of resources if the Express as percentage box was checked. If they are percentages, the values will be followed by a % (percent sign).
- Express as percentage check box
- If selected, the numbers in the Severely degraded threshold field, the minimum..maximum, and the [initial, default] are
percentages of resources, not counts of resources.
You can change the severely degraded threshold as follows:
- Specify a number less than or equal to the current maximum displayed to the right of the Severely degraded threshold field.
- Specify 0 to indicate that the aggregate resource always has a degraded status unless the unsatisfactory threshold has been reached.
- Specify -1 to indicate that this resource never reports a degraded status.
- Specify -2 to indicate that the resource uses the resource type default threshold value of default displayed to the right of the Severely degraded threshold field. This setting is available only for resources defined in RODM.
- Unsatisfactory
- The number, or
percentage, of real resources that must be reporting an exception state to cause the status of this aggregate to become unsatisfactory. This number is expressed as either a count of resources or a percentage of resources, as specified by the
Express as percentage box.
- minimum..maximum display
- The first set of numbers following the Unsatisfactory threshold field represents the current minimum and maximum values to which the Unsatisfactory threshold field can be set. These values can be either actual counts of resources or percentages of resources if the Express as percentage box is checked. If they are percentages, the values will be followed by a % (percent sign).
**
- [initial, default] display
- The second set of numbers following the Unsatisfactory threshold field represents:
- initial
- the value of the (unsatisfactory) threshold when the resource properties were initially retrieved.
- default
- the default value of the threshold from the resource type object in RODM. (This default value applies only to resources defined in RODM.)
These values can be either actual counts of resources or percentages of resources if the Express as percentage box was checked. If they are percentages, the values will be followed by a % (percent sign).
- Express as percentage check box
- If selected, the numbers in the Unsatisfactory threshold field, the minimum..maximum, and the [initial, default] are
percentages of resources, not counts of resources.
You can change the unsatisfactory threshold as follows:
- Specify a number less than or equal to the current maximum displayed to the right of the Unsatisfactory threshold field.
- Specify 0 to indicate that the aggregate resource always has an unsatisfactory status.
- Specify -1 to indicate that this resource never reports an unsatisfactory status.
- Specify -2 to indicate that the resource uses the resource
type default threshold value of default displayed to the right of the Unsatisfactory threshold field. This setting is available only for resources defined in RODM.
To set all values on the Aggregation page to the system default values, click the first Default button.
To reset all values on the Aggregation page to the initial values when you opened the window, click the first Reset button.
If a percentage is used for a threshold, the calculated count of resources (that results from applying the percentage to the total number of resources currently under the aggregate) is rounded up or down to the nearest integer number. If the calculated count is 1.5, for example, it will be rounded up to 2. If the actual count is less than 1.5, it will be rounded down to 1.
If a non-zero percentage is used for a threshold, the calculated count of resources (that results from applying the percentage to the total number of resources currently under the aggregate) will never be set to 0. All calculated counts that are less than 1 will be rounded up to 1.
**Note: If the value for minimum is set to -2 or -1, this can not be shown as a percentage.
