I just saw a press release by ExtraHop where they say that they have made a:
… Cloud Play with Industry-First Microsoft Hyper-V APM Solution and New Analysis-as-a-Service … The First Agentless APM Solution for Microsoft Hyper-V
It seems that this application performance monitoring solution uses a virtual switch extension to get at data as it passes through the virtual networking of virtual machines.
… a Hyper-V virtual appliance taking advantage of the new Hyper-V Virtual Switch capability … cross-tier operational visibility in a Hyper-V environment, correlating metrics across the application, network, web, database, and storage tiers
By working at the virtual switch layer they see all guest OSs and application traffic, and can monitor based on client/user/service interaction rather than on logs/events/monitors. There’s no agent, just an extension that sends data … to a virtual appliance monitoring station (I think). It’s different and interesting.
