PerformanceVision monitors network traffic by collecting network usage, performance, end-user experience and application transactions exchanged on physical, virtual, cloud or software-defined networks. PerformanceVision solutions are entirely agentless and have no impact on production networks. There is nothing to install, on neither server nor client side.
Deployment is quite straightforward as it requires no agent and no network architecture change. No outage is generated during its integration as no single point of failure (SPOF) is created on the network. We keep your IT safe!
PerformanceVision supports both flow and packet-based traffic analysis.
Most of the time PerformanceVision will rely on two mechanisms to capture network traffic:
- Port-mirroring (commonly called SPAN, with RSPAN and ERSPAN variations)
- Terminal access point (TAP) and Network Packet Brokers
The port mirroring is the most commonly used method to capture traffic. It is inexpensive, flexible in terms of how much traffic can be captured at once, and remotely configurable.
TAPs on the other hand are non-obtrusive, undetectable on the network, can deal with full-duplex and non-shared networks. They can monitor all packets (including hardware errors – MAC and media) and provide full visibility, including congestion situations. Usually, traffic will pass through even if the tap stops working or loses power, which minimizes traffic interruptions. For more on SPAN vs TAP, please read this blog post : How to capture traffic? (SPAN vs TAP)
For environments like small remote sites where traffic capture through port mirroring or TAPs is not possible, PerformanceVision also supports flow based performance analysis.
Data collection can be easily handled in hardware, virtual, mixed or hybrid environments, providing a full 360° view on performances for any kind of IT infrastructures.
