Preface

■ What you can do with Performance Management

The IT system is now an indispensable element in any business. Uninterrupted operation of the IT system provides around-the-clock support for conducting the business. While the costs of running such systems are trending downwards, it is also becoming more and more challenging to make changes in the system environment. Coping with such a situation makes it important to have the capability to quickly grasp your system's current status and to be able to respond proactively to the need to make changes.

Performance Management helps you to detect current problems in a timely manner and to obtain the information you will need to resolve problems. By checking the system's status regularly, you can also perform capacity planning for your system.

Performance Management provides a variety of windows that support your capability to monitor the applications running in your business system.

■ What is explained in this manual

This manual describes the basic procedures for configuring and running Performance Management. Its purpose is to help the reader understand the concepts and principal functions of Performance Management.

This manual is intended for the following users:

• Users who will be evaluating the installation of Performance Management

• Users who want to understand the concepts of Performance Management and to obtain in a short time an overview from configuration to operation

This manual assumes that the system configuration shown below is used. For details about operation with any other configuration, see the manuals listed in E.1 Related publications.

Monitoring manager

Performs central management of the monitoring agents. PFM - Manager is installed on the host that will be used as the monitoring manager.

Monitoring console server

Displays performance data collected from monitoring targets by the monitoring agents and Performance Management's configuration windows on the monitoring console. PFM - Web Console is installed on the host that will be used as the monitoring console server. In this manual, it is assumed that PFM - Web Console is installed on the host that is also configured as the monitoring manager.

Monitoring console

Checks the performance data collected from monitoring targets by the monitoring agents and changes Performance Management settings. The monitoring console can be displayed by connecting to the monitoring console server from a Web browser.

Monitoring agents

Collect performance data from monitoring targets. PFM - Base (the monitoring base program) and agent products for the monitoring targets are installed on the hosts that will be used as monitoring agents. In this manual, it is assumed that PFM - Agent Option for Platform is used as the agent products.

Note

• You can also install PFM - Manager and PFM - Web Console on separate hosts, thus configuring one host as the monitoring manager and the other host as the monitoring console server.

• You can install an agent product on the host on which PFM - Manager is installed to use this host also as a monitoring agent. In this case, there is no need to install PFM - Base.
