Predictive analysis

Troubleshooting means not only identifying the cause of a problem, but also a recommendation on how to fix it. ApplicationVantage provides a predictive analysis feature that allows users to see the impact of various performance adjustments on a transaction’s response time. In this way, the user can validate that performance will be improved, and by how much. Users can see the effects of varying the following metrics:

• Network: modifying bandwidth, latency and load
• Server: increasing/decreasing the power of a server
• Application: changing application turns for individual “thread” components, varying TCP window size

By adjusting these parameters one at a time, users can determine if the overall response time of the transaction is affected significantly. If it is, they can recommend a corrective course of action that will resolve the problem.

Predictive Analysis (Network Bandwidth) Vantage's Predictive Troubleshooting let's you see the effects of changing network, node, and application parameters to help validate corrective action to performance problems. This example shows the effects of changing bandwidth.

Predictive Analysis (Server Node) In this example, we can see the effects of increasing the computing power (Responsiveness) of one of the servers on the transaction response time.

Predictive Analysis (Application Thread) As shown in this example, reducing the number of application turns for a specific Microsoft SQL "Exec" command can significantly reduce transaction response times.

An easier path for troubleshooting

When you combine the thorough end-user experience monitoring of ClientVantage with the powerful performance analysis features of ApplicationVantage, it's easy to capture transaction paths as they execute and identify when service degrades—giving you a clear, definitive path to the problem. The result: You move from a reactive, firefighting mode into proactive, pre-emptive performance management. Having this type of data at your fingertips allows you to perform automatic, intelligent handoffs of problems to the most appropriate staff—applications, networks, servers or databases—without second-guessing or fingerpointing. Not only do you save the business time and money, but you also increase IT credibility with end users.
