The vSTREAM virtual appliance complements existing Adaptive Session Intelligence (ASI)-based instrumentation to provide the same level of visibility within virtualized and cloud infrastructures that is already possible in physical environments. The vSTREAM virtual appliance is ideal for monitoring service-critical traffic running within virtualized or cloud infrastructures, either locally on a host or as an aggregation point for multiple hosts. With complete visibility across physical, virtual and cloud networks, the vSTREAM virtual appliance presents real-time views of end-to-end call trace data and network-wide KPIs, to protect the reliability and availability of networks and application services.
PRTG Network Monitor runs on a Windows machine within your network, collecting various statistics from the machines, software, and devices which you designate. PRTG comes with an easy-to-use web interface with point-and-click configuration. You can easily share data from it with non-technical colleagues and customers, including via live graphs and custom reports. This will let you plan for network expansion, see what applications are using most of your connection, and make sure that no one is hogging the entire network just to torrent videos.
To monitor a large IT environment, it's important to be able to scale PRTG up. Paessler PRTG Enterprise Monitor includes all the proven capabilities of PRTG Network Monitor, which are enhanced by exclusive ITOps Board for a service-oriented, central overview of multiple PRTG servers.
