ASE Probes
Analysis Service Element Probes are data collection and network performance monitoring hardware devices placed on a wide area network (WAN) or Local Area Network (LAN) as part of the Visual Performance Management system. Data gathered by ASEs is stored in the Visual Performance Manager server and displayed and analyzed from the Web portal interface. As a service level management tool, ASEs indicate when services are being met, provide warnings when services start to degrade, and send alerts when services are not met.

Visual Performance Manager provides the ability to view individual interaction between client and server for any application.

• Complete response time analysis for streaming and non-streaming TCP and UDP applications.
• Monitor VoIP, video convergence and other multimedia applications that use UDP for transport
• Watch DNS & DHCP server performance and correlate to other applications that are dependant
• Aggregate statistics are kept for both TCP and UDP such as volume, data rate, data transfer time and application response time
• Performance statistics and transactions for custom TCP and UDP applications

VPM and APA in conjunction can provide detailed data around client-server transactions, allowing troubleshooting to focus on exactly what requests were sent to an application server at the time of a performance issue. The details of which client(s) were responsible for those transactions, and the content of those transactions (such as the specific HTTP GET request) which may shed more light on the issue at hand.

The GLS advantage

Using a series of in-house management processes in conjunction with the Fluke Networks tool set, GLS tracks all performance metrics on the client's Application Delivery Infrastructure and provides a detailed look at performance from the Data Center to the desktop. Reports of performance are based on real-world metric values which illustrate the network's actual performance.

As a part of ongoing management, GLS will perform an impact review on the customer's network to help analyze the potential effect of deploying a new Application on the network, facilitating change and growth of the client's infrastructure.
