The Visualization Performance and Fault Manager is an integral part of the Avaya Unified Communications Management (UCM) solution. This solution leads the industry in offering comprehensive, integrated management capabilities across data and voice over both wired and wireless networks.
The VPFM can discover every device on your network, even if you deploy equipment from numerous vendors. The application transforms complex network topology into simple-to-use, hierarchy-based maps, giving you clear, end-to-end views that help you quickly determine if network issues are physical or logical in nature.
With insight into how devices are connected and performing, you can zero in on aspects of the network and reduce your meantime to repair. Personnel can be dispatched quickly, which can result in less downtime, greater productivity, higher user satisfaction and a proactive rather than reactive network management environment.
The VPFM offers heterogeneous rather than domain-based network discovery with support for standards-, proprietary-, application- and OS-based discovery. Therefore, if a device is IP or SNMP-based, the VPFM can discover it. Discovery applies to servers, end nodes and operating systems.
Once devices are identified through discovery, VPFM takes complex network topologies - consisting of multiple geographic locations, multiple devices, hundreds or even thousands of devices connected to the network - and transforms them into simple hierarchy-based topology views. It shows degrees of device connectivity based on device function and where it is located in the network. The visualization function also includes VoIP service-based views that provide you with insight into the application. Having service-based views enables you to differentiate between physical connectivity and logical or application connectivity issues.
Once the issue(s) have been identified through network visualization, you can use the VPFM to monitor the network for faults. Using information collected from the network and the devices themselves, the VPFM performs status monitoring and sends the information that you need to do event correlation and route-cause analysis (RCA). The VPFM determines what the most likely cause of the network outage is by correlating all network events and determining the primary and secondary devices affected.
Through the VPFM, you can use performance management for two key activities: capacity planning and change monitoring within the network. In the latter case, the VPFM enables you to monitor modifications to the network - such as the addition of a switch - and observe how the device performs in the short term.
Diagnostic management allows the network operator to run and collect diagnostic data from network devices. The VPFM provides Layer 2 and 3 diagnostic information in an end-to-end connectivity rather than a hierarchical view. Through this capability, you can also print and export the data in graphical format.
The VPFM includes scope or device classification, a capability that provides a logical grouping of devices based on device type. By default, all devices are classified based on their discovered attributes, such as servers, routers and switches. You can also define the scope on a more granular basis that has relevance to your operations. Once grouped, you can treat the devices as a single unit for the purpose of collecting performance information, conducting events handling, status propagation, etc. For example, if a link fails for any of the devices within the defined logical unit, you can configure the VPFM to perform event handling on that classification.
