Successfully Implementing ITCAM for Transactions

Once a company recognizes that they need to monitor composite applications, their goals are normally too lofty for their own good, and this often leads to failure. You can avoid this by following a simple and straightforward implementation path, described here.
1. Start with one or two simple synthetic (robotic) transactions. Just get some transactions running so you'll know how the user experience is performing. Start with simple transactions that don't require many verification points or different variables. Rational Performance Tester is a very capable product, but learning how to use even a few of its features takes some time. You don't want to have your entire implementation stalled because of the time it takes to learn RPT. So start with some simple transactions to get some quick wins under your belt in the beginning. This will help foster goodwill for and confidence in the product.
2. SLOWLY work on adding additional agents to give you additional information. The easiest component to add in many cases is the Web Response Time agent, since it runs standalone (as opposed to, say, the J2EE Data Collector, which runs in the context of the JVM). However, your individual circumstance may alter the difficulty of implementation, so you may need to pick a different component. For example, your WebSphere group may be more willing to work with you than your infrastructure team, so the WAS Data Collector may be easier to implement than the WRT agent. Whatever the case may be, you want to try to have as much success as possible while ruffling the smallest number of feathers as possible. Identify the components that you can install most easily, and work with those.
3. Once you've gathered data in addition to the synthetic transaction information, you can use that success to get more support for moving forward with the implementation. Continue to find the next component that's easiest to deploy, and leverage that success to allow you to move on to the next comp
