Introduction

As IT infrastructures evolve into being business-critical, high availability and peak performance of the IT infrastructure is becoming as critical as reliability is to a telephone network. In such infrastructures, it is imperative to determine in real-time when service failures or slowdown problems occur, and to accurately pin-point which step(s) in the service access are impacting the end-user experience. Speedy problem detection and accurate diagnosis can reduce service downtime and the consequent business impact of critical IT services.

eG's client emulation and monitoring capability goes well beyond basic protocol-level up/down testing. IT administrators can record typical user accesses to mission-critical infrastructure services, and later have eG agents periodically playback the recorded accesses using the exact same client applications that users employ to access a service. The eG client emulator effectively simulates multi-step user interactions with a service (e.g., login, browse, submit data, fill-in forms, etc.).

By collecting availability and response time statistics for the complete service interaction and comparing the metrics with time-of-day, auto-generated or administrator-defined fixed thresholds, the eG client emulator immediately alerts administrators during potential service outages or slowdowns.

By comparing the response times across each of the steps of a multi-step service access, administrators can detect the exact step(s) that could be causing user-visible slowdowns. Furthermore, using its patented auto-triage capability, the eG Enterprise suite is able to correlate the end-to-end service performance indicators provided by the eG client emulator with critical indicators of network, system, and application availability, performance, and usage to pin-point where the root-cause of a slow-down lies. Customers can use the integrated solution to improve the quality of their service offerings, thereby enhancing their competitive positioning, lowering their operations costs, and optimizing the usage of their infrastructure.

Since it is capable of supporting web-based or native client applications, the eG Enterprise suite can handle web-based as well as proprietary/native client applications (and even thin-client/Citrix applications) equally well.
