With baselining completed, on going 24/7/365 Performance Threshold Notification and Performance Management begins, which provides the client with the information needed to properly track Application Delivery Infrastructure performance, and to make changes when needed to correct existing issues, or to prevent potential problems from arising.

Using advanced performance diagnostics, problem isolation support is performed on a continual basis to ensure that the client's infrastructure is operating at peak efficiency and that issues are resolved in the least amount of time possible. The pro-active monitoring systems and personnel in the GLS NOC provide an experienced layer of monitoring and performance management support to any client's network.

In addition to managing the customer's Application Performance monitoring tools, GLS provides clients with direct access to the Fluke Networks VPM interface, providing the client with all the raw data used by the GLS NOC for client internal support staff to have real-time access to the same information as needed, improving efficiency when working to remediate an issue, or to validate performance improvement after changes have been made to increase performance.

The tools in the Fluke Networks VPM suite provide very powerful features from high-level overview summaries to packet-level transaction details. The Visual Performance Manager itself acts as a centralized interface for the three main Fluke Networks performance management products: ASE network Probes, NetFlow Tracker, and the powerful Application Performance Appliance.

Each of these tools works in conjunction to provide deeper levels of insight into the client's network application performance, and to aid in isolation and troubleshooting of problems.

The Fluke Networks VPM interface displays statistical performance data in a number of ways, including detailed numerical tables and at-a-glance graphical charts with specific metric overlays for comparison and correlation analysis. These dynamic methods of viewing data increase efficiency in understanding both the real world effect of a performance issue, as well as in tracking down the source of the problem and addressing it.

Components of Visual Performance Manager

APA
The application performance appliance is a proprietary hardware/software component that feeds application performance data to the Visual Performance Manager server. The application performance appliance is a passive device that is deployed in the data centers where the server farms reside. It collects data via tap or span port of the switches which interconnect Web servers, application servers, database servers, streaming media servers, and DNS/ DHCP servers. Through this connection, the application performance appliance is privy to all client traffic to the Web servers, requests to the application servers, and subsequent queries to the database servers - no software agents are required at the remote client-side.

NetFlow Tracker
NetFlow Tracker expands the breadth, depth and coverage of Visual Performance Manager by providing visibility into network flows for in-depth LAN/WAN and application trouble shooting, trend analysis and capacity planning.
