Modern Application Performance Management (APM) solutions can be tremendously helpful in delivering end-to-end visibility into the application delivery chain: across all tiers and network sections, all the way to the end user. In previous blog posts we showed how to narrow down to various root causes of the problems that the end users might experience. Those issues ranged from infrastructure through application and network, and through the end-user client application or inefficient use of the software. When the problem comes from the end user application, e.g., a Web 2.0 Web site, user experience management (UEM) solutions can offer broad analysis of possible root causes. Similarly, when an APM fault domain algorithm points to the application, the DevOps team can go deep into the actually executed code and database queries to identify the root cause of the problem. ...

What It Takes to Deliver User Experience Management

User experience can boost or kill your revenue. Unhappy users are likely to abandon a service they struggle with and go to your competitors. To effectively manage the experience of your users, you need to efficiently monitor and understand their transactions in your mobile, web and enterprise applications. More important and often overlooked, the practice of User Experience Management (UEM) does not end in the client application. Common user experience tools fail to ensure holistic UEM the same way many think performance management is only based on analyzing server logs. Neither ... (more)

Application Performance Problems? When to Blame the Untrained End User

In my previous posts I wrote about how important it is to have end-to-end visibility into SAP in order to avoid serious problems in our delivery chain or to discover that application performance degradation was caused by malfunctioning hardware. One of our New Zealand customers, Fonterra, who is the world's largest exporter of dairy products, uses SAP to support its delivery chain of dairy products made from 22 billion liters of milk collected each year. In this article we show how Fonterra uses a new generation of APM tools that provide both user and transactional insight, as we... (more)

How Workstation Hardware Problems Can Affect SAP Performance Perception

Introducing SAP is a cost that makes everyone very cautious about the return on this investment. Performance problems with SAP delivery can quickly propagate to seriously affect business operations and lead to tedious war room scenarios. End-user complaints will usually point towards the SAP team, the SAP team will blame the network, and IT operations team will fight back. But what if the root cause of the problem is something altogether different. The inability to quickly determine the root cause of the performance problem often leads to war room scenarios, especially when the mo... (more)

Can You See the Storm Coming?

As much as we try to avoid performance problems, they do happen. It is inevitable. But it is possible to learn to react fast, and in some occasions fast enough that the impact on the end users is negligible. Despite operators' best efforts, 73% of performance issues are reported by users, according to "APM: Getting IT on the C-Level's agenda" report by Aberdeen Group. This number is quite large considering that less than 5% of all users typically bother to complain at all. User Experience has a significant impact on business success. According to the Aberdeen report, poor perform... (more)
