The availability percentage calculation takes into account planned down time, which can be configured through Precise AdminPoint. For more information, see the Precise Administration Guide.
When Report Manager generates an Availability report, it checks if an instance availability falls below its availability threshold, unless there is no information (regarding availability) for the Tier. For example, a newly installed Tier may not have data currently available regarding availability; in this case a bar labeled Unknown appears on the graph. If an instance availability falls below its availability threshold, Report Manager sends an alert to Alerts. Likewise, when working in Alerts, you can drill down to the relevant Availability report from the Alerts user interface. For more information, see the Alerts User's Guide.
About the Instance-level Availability report structure
The Instance-level Availability report structure consists of the following sections:
- About the Instance-level Availability report - opening page
- About the Tier Availability table
- About the Instance-level Availability Overtime graphs
| Anchor | ||||
|---|---|---|---|---|
|
The opening page of the Instance-level Availability report is similar to all the pre-defined reports except that the summary section provides information related to the specific report as follows:
- Number of reported instances, and their average and minimal availability within the report period.
| Anchor | ||||
|---|---|---|---|---|
|
The Tier Availability Table displays the availability details of each instance of the Tier. These details include the Average and Minimal Availability Percentage, and the Availability Threshold. The Availability Threshold can be configured through Precise AdminPoint. If the Instance Availability is below the threshold, Report Manager indicates its data in red. If there is no data currently available regarding availability, Report Manager indicates no data as Unknown and in blue.
By default, Report Manager generates Overtime graphs only for instances whose availability is below their threshold. Therefore, only for these instances, the names in the Instance column of the table are links, while the others are not links. You can change this default setting so that all the names will be links. See Setting Availability report properties - filters tab on page 46.

Report Manager provides two types of Load Balancing reports:
- Cross-Tiers Load Balancing
...
- Report. This report type compares all the servers installed in the application, and displays a high level balancing view of the entire application.
- Tier Load Balancing
...
- Report. This report type assists you only to balance the machines in which instances of the Tier are currently running.
Report Manager compares the servers' load using the operating system counters. Therefore, these reports are only available when Insight's OS Tier is installed.
For more information, see the Precise Installation Guide. The operating system counters include:• CPU
- CPU usage (%)
...
- CPU load - average number of processes waiting for CPU
...
- Paging
Report Manager compares the servers also by the Tier's Total Time, Volume, and Average Time. To overcome the differences among the servers' power (such as, CPU and memory), the different servers are assigned with weights. By default, a UNIX server is weighted 7 and a PC is weighted 4. The Total and Average Times are multiplied by the weight. The weights of the servers are stored in the Performance Management Database and can be updated using appropriate SQL UPDATE statements.
...
Report Manager generates the Tier Load Balancing report for all the servers that run instances of the specified Tier (Report Manager does not generate the Tier Load Balancing report for Tiers that contain a single server).
