Drill-down is supported down to individual network connection (flow) level visualizing the traffic distribution by time. NetFlow analysis delivers ad-hoc reports about top talking applications, servers, workstations for a given time period. This enables detailed post mortem analysis of slowdowns and increased response times and pinpointing the application or workstation that caused it. NetFlow analysisĭetailed traffic data – down to individual session information – is kept for days in the system. PVSR with its native NetFlow support delivers detailed monitoring data about network traffic by visualizing it grouped by application, QoS class or site. Without proper insight into traffic it is very difficult – and sometimes impossible – to find the cause of slowdowns and increased response times. Network performance is responsible for a large part of end user experience when remote sites or users connect to the datacenter through VPN or dedicated WAN links. NetFlow analysis is indispensable tool for network operations staff by identifying network performance bottlenecks and source of service quality problems.
