14.11 Application management
The tooling supplied with the IBM WAS products provides facilities to monitor the applications you deploy on it, but they provide no cross-platform or cross-enterprise view of all your deployed applications. This is where application management tools come into play. They provide a transactional view over multiple servers and platforms throughout the enterprise.

As depicted in Figure 14-23 the problem and resolution process can be split into the following steps:
| 1. | Identify and prioritize |
| 2. | Isolate and assign |
| 3. | Diagnose |
| 4. | Fix |
These steps are supported by two Tivoli products that deliver application management functionality to a specific group of users:
| - | Tivoli Monitoring for Transaction Performance (TMTP) |
Used by 1st level support, operations, and application helpdesks to isolate and identify performance problems through many technologies and across multiple servers.
| - | WebSphere Studio Application Monitor (WSAM) |
Used by SMEs (Subject Matter Experts) to drill down into J2EE applications to find the source of an application performance problem.
The application management products WebSphere Studio Application Monitor and TMTP have the following unique capabilities:
| - | No manual instrumentation or application reengineering required |
| - | Real-time problem determination with extensive drilldown capabilities |
| - | Instance-level data capture correlates specific transactions with an end user experience |
| - | Pinpoint problems that are masked with only aggregated data |
