The Tier Load Balancing report structure consists of the following sections:
- About the Tier Load Balancing report - opening page
- About OS Summary graphs
- About OS Overtime graphs
- About Tier Overtime graphs
- About Tier Consumption Summary graphs
| Anchor | ||||
|---|---|---|---|---|
|
The opening page of the Tier Load Balancing reports is similar to all the pre-defined reports except that the summary section provides information related to the specific report as follows:
- Number of servers that are overloaded and number of servers whose load is significantly under the average load (the number of servers that have one of the OS counters significantly above or under the average value).
- For each OS counter, the number of servers overloaded and underloaded related to the counter’s average value.

|---|---|---|---|---|
|
Report Manager generates an OS Summary graph for each balanced OS counter, such as CPU Usage and CPU Load and Paging. This graph displays the Counter Summarized Value versus the Average Load, for each reported machine.

Report Manager generates an OS Overtime graph for each balanced OS counter, such as CPU Usage, CPU Load and Paging. This graph displays an Overtime Behavior graph of the Top n and Bottom m Servers compared to the Counter Average Value.
| Anchor | ||||
|---|---|---|---|---|
|
This graph displays a Summary of the Overtime Behavior of the reported Tier. It displays the Actual Values of the counters for the Top n and Bottom m Servers.
Report Manager generates a Tier Overtime graph for each of the following counters:
- Total Time
- Average Time
- Volume

This graph displays a Summary of the Counter Values for each installed Tier on the Top n and Bottom m Servers. Report Manager generates a Tier Consumption Summary graph for each of the following counters:
- Total Time
- Average Time
- Volume
About Load Balancing report properties
The Properties dialog box of the Load Balancing report contains three tabs in which you can set the properties:
- Setting Load Balancing report properties - general tab
- Setting Load Balancing report properties - time frame tab
- Setting Load Balancing report properties - filters tab
In addition to these three tabs, there is a Description tab which displays a textual description of the report structure and contents.
| Anchor | ||||

The General tab contains the following properties:
- Report an exception when a counter exceeds average by more than n
...
- percent. This property determines the threshold percentage that Report Manager considers the server consumption as overloaded.
- Report an exception when a counter falls below the average by more than n
...
- percent. This property determines the threshold percentage that Report Manager considers the server consumption as under the average consumption. This property is optional. If you disable this property, Report Manager does not report on server whose consumption is less than the average
- Report top n
...
- servers. This property determines the number of servers that are most overloaded.
- Report bottom m
...
- servers. This property determines the number of servers that are most underutilized.
To set Load Balancing report properties - general tab
- Type the desired percent number threshold that Report Manager will use to report servers whose consumption is overloaded.
- If desired, check the option and type a percent number if you want Report Manager to report on servers whose consumption is less than the average.
- Type the desired number of servers to report that are most overloaded.
- Type the desired number of servers to report that are most underutilized.
- Click OK to approve.

The Time Frame tab contains the following properties:
- Detailed Overtime graph will show Specifies show. Specifies the period for the Overtime graphs. (This property is not available for the Cross-Tiers report.)
- Detect exceptions Specifies exceptions. Specifies the period by which Report Manager detects exceptions. Set this period to the same or as part of the period specified in the Detailed overtime graph will show property.
- Summary graphs depict This depict. This property determines the period, which is used for a Summary graph calculation. This period should be included within detailed Overtime graph period. This property is not presented in Cross-Tiers report.
- Analyze the following hour groups only Specifies only. Specifies the hour groups (for example, All, Night, Day, and Weekend) to include in the report.
...
- Select the time period for Overtime graphs.
- Select the time period by which Report Manager detects exceptions.

The Filters tab contains the following properties:
- Analyze only the following instances Formatinstances. Format: wildcard1,wildcard2,... where a wildcard is a string that may contain asterisks. (This property is not available for the Cross-Tiers report.)
- Analyze only the following servers The servers. The format is the same as in the first property.

When Report Manager generates a Capacity Planning report, it checks if the expected increase in a forecasted counter exceeds the baseline by more than the increase threshold. In this case, it sends an alert to Alerts. Likewise, when working in Alerts, you can drill down to the relevant Capacity Planning report from the Alerts user interface. For more information, see the Precise Alerts User 's Guide.
About the Capacity Planning report structure
A Capacity Planning report structure consists of the following sections:
- About the Capacity Planning report - opening page
- About the Capacity Planning report - heat matrix
- About Behavior and Forecast overtime graphs
| Anchor | ||||
|---|---|---|---|---|
|
The opening page of the Tier Capacity Planning reports is similar to all the pre-defined reports except that the summary section provides information related to the specific report as follows:
- For each forecasted counter, the average increase of the counter consumption at the end of the forecast period.
| Anchor | ||||
|---|---|---|---|---|
|
The Heat Matrix page indicates, in a tabular format, the most significant consumption increase of the forecasted counters. Each row in the Heat Matrix represents a different instance. Each column represents a different forecasted counter. The cell color indicates the increase level of the counter related to its increase thresholds. You can set the increase thresholds through the Capacity planning report - general tab of the report Properties dialog box. The instance name is a link to the instance’s Overtime Behavior graphs.

|
Report Manager generates - for each instance - a Behavior and Forecast Overtime graph for each predicted counter. Each Overtime graph presents the past behavior, baseline, and forecast of the counter.
The Behavior and Forecast Overtime graphs page contain a launching link to the related Precise or Insight product. You can click the launching link for further investigation in context of the displayed instance.
About Capacity Planning report properties
The Properties dialog box of the Capacity Planning report contains three tabs in which you can set the properties:
- Setting Capacity Planning report properties - general tab

The General tab contains the following properties:
- Forecast the following counters This counters. This property includes an option box for each counter of the instance. Select the counters, by which Report Manager calculates the forecast.
- Escalate the increase when current consumption is exceeded by more than n percent This percent. This property determines the threshold percentage that Report Manager considers as the first level increase in instance’s instance's consumption (appears yellow in the Heat Matrix Table).
- Then, escalate increase when the current consumption is exceeded by more than n percent This percent. This property determines the threshold percentage that Report Manager considers as the second level increase in instance’s instance's consumption (appears orange in the Heat Matrix Table). This property is optional. If you do not select it and specify the percentage, only one color will be presented in the Heat Matrix Table.
- Then, escalate increase when the current consumption is exceeded by more than n percent This percent. This property determines the threshold percentage that Report Manager considers as the third level increase in instance’s instance's consumption (appears red in the Heat Matrix Table). This property is optional. If you do not select it and specify the percentage, only two colors will be presented in the Heat Matrix Table.
...
- Check the desired number of counters by which Report Manager will calculate the forecast.
- Type the threshold percent number that Report Manager will consider as the first level increase in instance consumption.
