Bottlenecks and performance issues in the PVS servers might cause long boot times and the inaccessibility of desktops and applications. Monitoring of PVS servers and their performance is therefore essential. The keys to proactively identifying PVS problems are in-depth visibility of key performance indicators of the server operating system (MEM, IOPS), the infrastructure (PVS services, PVS streaming errors), and the underlying component layers (PVS sites, vDisks, target devices, etc.).
