10.3 System Management and monitoring using Tivoli products

In order to provide an overview of how to implement performance, availability, configuration and operation management, core IBM Tivoli products will be listed and described at a high level. It is not the objective of this redbook to discuss these system management products in detail.

IBM Tivoli Enterprise Console (TEC)

The IBM Tivoli Enterprise Console product is a powerful, rules-based event management application that integrates network, systems, database, and application management. It offers a centralized, global view of your computing enterprise while ensuring the high availability of your application and computing resources. It collects, processes, and automatically responds to common management events, such as a database server that is not responding, a lost network connection, or a successfully completed batch processing job. It acts as a central collection point for alarms and events from a variety of sources, including those from other Tivoli software applications, custom applications, network management platforms, and relational database systems.

IBM Tivoli Monitoring

IBM Tivoli Monitoring provides monitoring for essential system resources such as performance, including disks, CPU and applications, to detect bottlenecks and potential problems, and to automatically recover from critical situations.

IBM Tivoli Monitoring for Web Infrastructure

IBM Tivoli Monitoring for Web Infrastructure is a critical tool to help ensure the optimal performance and availability of both application servers and the associated Web servers that feed them. It provides a single point of control to enable IT organizations to understand the health of a Web-based environment's key elements. It allows administrators to quickly identify problems, alert appropriate personnel as required, and offer a means for automated problem correction.

IBM Tivoli Monitoring for Databases

The IBM Tivoli Monitoring for Databases ensures the availability and optimal performance of DB2, Oracle, and Informix database servers.

IBM Tivoli Monitoring for Messaging and Collaboration

IBM Tivoli Monitoring for Messaging and Collaboration monitors the status of Domino servers, identifies server and system problems in real time, notifies administrators and takes automated actions to resolve Domino server problems. The product also collects monitoring data to help you analyze performance and trends, and helps you address problems before they affect end users.

IBM Tivoli Netview

IBM Tivoli NetView discovers TCP/IP networks, displays network topologies, correlates and manages events and SNMP traps, monitors network health, and gathers performance data. Tivoli NetView meets the needs of managers of large networks by providing the scalability and flexibility to manage mission-critical environments.

IBM Tivoli Storage Manager

IBM Tivoli Storage Manager protects data from hardware failures, errors, and unforeseen disasters by storing back-up and archive copies in offline and offsite storage. It is responsible for implementing the data contingency (back-up/restore) policy.

10.3.1 Integrating System Management in the Pervasive Portal solution

Figure 10-6 on page 232 shows an example of how to integrate the system management infrastructure in a Pervasive Portal solution using the Tivoli products. In order to understand the security layer for Data Contingency and System Management, refer to 10.1, "System management activities" on page 220.

Figure 10-6: System Management and Data Contingency represented in the operational model

The system management solution in this example is composed of the Tivoli Netview that manages the network infrastructure, the Tivoli Monitoring that manages operational systems, hardware resources such as memory and disk and specific applications like WebSphere and DB2, and Tivoli Enterprise Console, which consolidates all the events created by Tivoli Netview and Monitoring and generates alarms. To manage the specific applications, you will require Tivoli Monitoring as the server and the Tivoli agents (Tivoli Monitoring for Web Infrastructure, for Databases, for Messaging and Collaboration) running with each specific application.

The data contingency is provided by the Tivoli Storage Manager that backs up data using the Storage Area Network for the equipment connected to it, using a LAN ( dotted line) for the other equipment that also needs backing up. This sample diagram does not take care which components need back-up and includes all of them in the back-up LAN or SAN. Usually, databases have a lot of data to back up and it is recommended, in terms of performance and security, to use a SAN. So as not interfere in the data access performance and integrity of the databases while performing a back-up, some components can be used that allow the online back-up, such as the Tivoli Storage Manager for Databases.

Note	Because of the extensive details of the previous diagram, it is difficult to read some parts on a printout. If you like to read the details, please use the original PDF document and magnify the area you want to see.
