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:

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:

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:

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.

Using a Percentage

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.
