Fast Problem Resolution Requires Fast Answers to These Questions:
- Where on the network was the problem introduced?
- Was the DSCP value changed, and if so, where?
- Why wasn’t the traffic prioritized correctly?
- Was any of the traffic dynamically re-routed across the network?
Scrutinizer can monitor traffic by device, user, and application and then visualize the data in easily customizable reports. A single report can show response times across the entire network, network segments, and the servers themselves to quickly dig in and isolate the source of the trouble.
Integration with Cisco Application Visibility and Control (AVC) and Performance Monitoring
Plixer was the first Cisco NetFlow Partner to become certified for Cisco Medianet performance monitoring reports. This is a Flexible NetFlow technology that exports details on round trip time, jitter, packet loss, and other VoIP metrics. In addition, Scrutinizer now also collects NetFlow and metadata from Cisco Application Visibility and Control (AVC).
“Scrutinizer provides detailed reports including the medianet performance monitoring statistics (round trip time, jitter, packet loss, bit/byte and packets, MAC Addresses, IP Addresses, VLANs, Domains, application recognition) to help you monitor and troubleshoot video, voice and data applications. These reports can help the network operator perform fault isolation of network issues affecting rich media applications, as well as track historical performance of various parts of the network.“- Patricia Costa – Product Manager, Cisco Systems
NetCaller ID and Codec
New developments in NetFlow and IPFIX have led to some hardware vendors exporting VoIP details on Caller ID and Codec. Not only can Scrutinizer tell you the phone numbers dialed, it can report on the length of each call, as well as where the packet loss or jitter was introduced. End-to-end, hop-by-hop visibility shortens the troubleshooting process and restores normal operations faster.
Performance Routing NetFlow
Cisco Performance Routing (PfR) can export IP SLA details using Flexible NetFlow. When a router determines that a connection is congested, it will evaluate existing flows and reroute traffic over different connections, ensuring priority to time-sensitive traffic. By using PfR and Cisco Performance Monitoring together with Plixer’s Flow Hopper, administrators gain end-to-end network visibility on a link-by-link, hop-by-hop basis—all with NetFlow.line-break
How to Monitor VoIP Traffic
We get questions almost daily, asking, “How can we use NetFlow to troubleshoot call quality issues?” Customers are usually shocked when we show them how easy it is to do.
Measuring Application Response Time Using IPFIX (NetFlow)
Isolating the source of an application’s slowness has long been a study of both traffic congestion and round trip time. This document explains how to pinpoint
the source of latency within a connection by reporting on flows.
