Performance diagnostics using Itcam for WebSphere

Background information

As the application of Java EE multi-tier architecture is widely deployed at the enterprise level, the performance problem from this kind of architecture is getting more and more attention. The multi-layer nature of the architecture makes performance problems occur, it takes a lot of time and effort to gradually troubleshoot, in order to locate performance bottlenecks, which is often a thankless process, more importantly, in the face of critical business systems, performance issues on the impact of business operations is direct and obvious.

Was is one of the most widely used application servers in the industry, providing foundation support for key business systems in the financial, telecommunication and manufacturing industries, and Tivoli is an outstanding IT infrastructure and application management software, how to effectively apply IT management software to the infrastructure software, Improve the effectiveness and accuracy of day-to-day management, ITCAM for WebSphere may be able to give some answers.

ITCAM Simple Introduction

ITCAM, IBM Tivoli Composite Application Management, is an integral part of Tivoli in the five IBM brand software series, focusing on the management of applications under multi-tier architectures, the term composite, that is, synthetic, meaning Applications are synthesized in layers.

The ITCAM itself consists of a range of products, ITCAM for SOA management, and ITCAM for Java for other Java application Server management, while ITCAM for WebSphere exists as a separate product family.

ITCAM for WebSphere provides a functional set of advanced features such as performance analysis, thread deadlock analysis, and memory leak analysis, which enables advanced diagnostics of enterprise-wide is by using a single management console.

ITCAM's own architecture is divided into two tiers: the data collection layer and the Management Service layer, as shown in Figure 1:
