FLOWSENSOR Product Details

The StealthWatch FlowSensor appliance delivers flow-based Response Time Management (RTM) that provides comprehensive visibility of network and server performance metrics. StealthWatch FlowSensor AE The StealthWatch FlowSensor extends the StealthWatch System's visibility into areas of the network that lack flow data or where traditional Ethernet sensor technology is cost prohibitive. The appliance translates Ethernet communications into lightweight "flow records" which are sent to StealthWatch Flow Collectors for detailed analysis. By delivering flow-by-flow visibility, StealthWatch provides network and server performance metrics, including connection information such as Round Trip Time (RTT), Server Response Time (SRT) and Retransmission Ratio (RT%).

In today's complex business environments, organizations demand continuous access to and fast performance from the IT systems they use. When these fail or slow down, network security and operations teams must be able to isolate the root cause and restore performance quickly and efficiently. Visibility into all areas of the network is critical to answering questions such as:

Does the problem relate to a misconfigured application or a virus on the user's workstation? Has a router interface gone bad? Is a particular server overloaded with traffic? Has a virtual machine in a sensitive area of the system been compromised?

More and more, organizations are recognizing the importance of NetFlowTM to provide the kinds of detail they need to ensure continuous, satisfactory and secure network performance. However, the monitoring solution they require must be scalable and cost-effective, using as few resources as possible. The StealthWatch FlowSensor from Lancope, the leader in NetFlow collection and analysis, provides the all-encompassing visibility needed anywhere from branch offices to 10G data centers at a fraction of the cost of traditional probe-based devices.

The StealthWatch FlowSensor is available either as a lightweight 1U appliance as a virtual image that generates NetFlow for areas that are not NetFlow-enabled, or where operators need deeper visibility into packet data.

"Through 2012, more than 80% of application performance and availability failures will be blamed on network problems, but the network will represent less than 20% of the root cause." � Gartner*

Simply direct the FlowSensor toward any NetFlow v9capable flow collector to derive the valuable detailed traffic statistics that only NetFlow can deliver. When combined with the StealthWatch Xe for NetFlow Collector, the FlowSensor also provides deep insight into performance metrics and behavioral indicators.

Visibility + Contextual Intelligence = Quick Problem Identification + Isolation of Root Cause

The inability to diagnose performance complaints or pinpoint security-related incidents can cause costly troubleshooting delays and exacerbate user experience. Working with the StealthWatch system, the FlowSensor delivers contextual flow-based server and network Response Time Management (RTM) information. This data helps operators quickly determine if the root cause of latency lies with the user's workstation, the network or the application server. If the cause lies at the host, StealthWatch can even identify the user involved. Using StealthWatch's unique drill-down features, operators can go from issue to root cause within seconds, thereby reducing Mean Time to Know (MTTK), enhancing operational efficiency and reducing costs.

The StealthWatch FlowSensor delivers traffic statistics to any NetFlow v9-capable collector. When combined with other StealthWatch components, IT personnel can see key performance metrics via user-friendly graphs that help operators quickly identify the root cause of issues.

Low-Cost, Scalable Solution from Branch Offices to 10G Data Centers

The FlowSensor is available in a variety of models starting with the FlowSensor 250, which offers a throughput of 100 Mbps for lower bandwidth areas of the network, up to the FlowSensor 3000, for monitoring 10G networks. Lancope also offers a virtual edition, the FlowSensor VE. Having very little impact on system resources, the FlowSensor VE monitors traffic traveling into and out of VMware vSphere/ESXi hosts and between the virtual machines within those hosts, effectively eliminating the communications blind spot often associated with virtualized environments. With the FlowSensor VE, operators can see the same detailed traffic statistics for their virtual networks as they can see for their physical networks.

Achieve comprehensive visibility into areas of the network that lack flow data or where traditional Ethernet sensor technology is too costly to deploy. Manage network communications down to the individual flow by capturing, storing and reporting communications across the network, delivering unmatched visibility into the nature of the organization's network traffic. Pinpoint security-related network problems by generating NetFlow data that the StealthWatch Xe for NetFlow Collector analyzes to identify and prioritize suspicious network communications, including botnets, worms, policy violations and misconfigured network devices. Troubleshoot network latency and application performance issues through quick diagnosis and resolution of end-user performance complaints.

The StealthWatch FlowSensor appliance easily connects into existing infrastructure via a SPAN, mirror port, or Ethernet TAP. The FlowSensor is a lightweight image that simply installs inside each vSphere/ESXi host and connects promiscuously to the virtual switches. Once installed, the FlowSensor passively captures Ethernet frames from the traffic it observes and creates NetFlow records containing valuable session statistics that pertain to conversational pairs, bit rates and packet rates. The FlowSensor then sends these records to any flow collector that supports NetFlow v9.

As the FlowSensor observes network traffic, it also calculates various performance metrics for each flow and exports them as NetFlow v9 records using Lancope's flow template. Because the FlowSensor has packetlevel visibility, it can calculate round-trip time (RTT), server response time (SRT) and packet loss for TCP sessions. It includes all of these additional fields in the NetFlow records that it sends to the StealthWatch Xe for NetFlow Collector. These flow performance indicators provide insight into the latency introduced by the network, as well as the server-side application.
