Precise for SAP offers a wide range of data presentations that provide IT professionals with the information necessary to manage SAP client/server systems. Precise for SAP analyzes SAP system performance and applications and helps you to effectively direct resources and enhance system use.
...
The Precise user interface makes the data available as a series of views accessible from a standard web browser. Information is organized according to your company's business structure, geographic locations, and SAP system characteristics. It can provide the views that show information according to your enterprise's departments or business organizations. In addition, it can show information by location or according to application server performance or the service provided to users of a specific application. Basic information about your business organization, departments, and the key network locations to be monitored must be provided to the Precise for SAP application. This ensures that it generates appropriate views and provides optimum analysis.
Improved performance management
IT staff frequently search for answers to questions like Why did the user experience poor response time yesterday? or Where is the transaction spending the most time?
...
Precise for SAP also enables you to focus on and drill down to individual transactions, users, organizations, locations, application server, or applications in your system that are responsible for heavy consumption of system resources. This lets you find the definitive root cause of performance degradation.
Integrating with other Precise products
Precise for SAP has been integrated with Precise Insight, Alerts, Report Manager, Precise Custom Portal, Precise for SQL Server, and Precise for Oracle in addition to the PMDB.
...
The Precise Custom Portal is a lightweight, configurable portal application that provides access to various types of data from different applications. The Precise Custom Portal features a Web-based view. It is highly customizable and extensible, allowing you to build a dashboard for each user or each function within your organization. For example, you can build a dashboard for all the information that a system administrator or director of IT operations would need to constantly follow up on. This component is automatically installed as part of the Precise framework installation. For more information, see the the Precise Custom Portal User 's Guide.
Precise for SQL Server allows you to go into the detailed transaction information that is contained in the SQL database while maintaining the context you have specified while working in Precise for SAP. For more information, see the Precise for SQL Server User's Guide or Online Help.
The PMDB is the repository of the Precise for SAP suite, which stores application performance data for long-term analysis and trending reports. The data collected by the Precise product suite. For more information, see the the Precise Administration Guide or AdminPoint Online Help.

About Precise for SAP Collectors
Precise for SAP Collectors are implemented as NT services (no support is provided for UNIX Collectors). The Collectors can only reside on a Windows OS machine (they do not need to be installed on an SAP application server). See Precise Installation Requirements in the Precise Installation GuideSee Precise minimum requirements for installation.
One Collector can collect data from many remote SAP systems. The Collector stores the data it collects into cache files in the LOG folder.
The following table describes the various Collectors.

| Availability | The Availability Collector supplies the availability data of each and every application server in all monitored SAP systems. The Collector calls an RFC Ping method to check for application server availability. This data is then written to the cache files and aggregated in the FocalPoint before being loaded into the PMDB. The application server availability data is computed along with the locale availability data to produce overall system availability data. |
...
| Locale | The Locale Collector supplies network information. When a locale is configured, destination machines are configured for that locale. The Locale Collector pings these destination machines using the TCP/IP method and returns information about the availability of these destinations. This data is then written into the cache files and aggregated by the FocalPoint before loading it into the PMDB. The aggregated data is used as the locale availability information for Precise for SAP. It is also computed together with the application server availability to produce overall system availability data. |
About the Precise for SAP FocalPoint Manager
The FocalPoint Manager handles several unrelated tasks:
- Answering data requests from GUI or other Precise products.
- Performing infrastructure tasks (installation and agent manager tasks).
About the Precise for SAP Data loader
The Data loader loads the collected data, processes the data, and prepares it for loading into the PMDB. Prior to the statistics load process the Data loader is in charge of processing the data collected.
...
- Summarizes data by time slices.
- Manages the dimension tables (substituting identifiers by keys and adding new dimension records if they don't exist).
- Transforms the union dialog steps into business transactions.
- Calculates SLA values for business transactions.
- Determines the planned downtime status for each availability time slice.
- Converts the time to FocalPoint GMT time.

Precise for SAP stores a complete history of your SAP system activity in the PMDB. This provides you with a performance tracking tool. It gives you the ability to assess SAP system performance trends and analyze changes in SAP system activities over long periods of time. This data is vital for identifying patterns in resource consumption and predicting future resource consumption in your SAP system.
...
The Precise for SAP Collector agents run from a remote dedicated server. This server connects to your systems application servers using a low overhead, accurate, and comprehensive sampling technology (no software components are installed on your application server machines). The server collects performance and availability data from your SAP system. It is then analyzed and summarized. You can later access this data using the user interface to perform long-term evaluations of performance.
