You can’t rely on traditional performance monitoring tools for monitoring a virtual infrastructure. Using the same tools that you would in a physical environment often results in inaccurate and incomplete metrics.
For the most accurate method, you need to know which performance monitoring tools to use and what to monitor in your infrastructure.
Physical performance monitoring tools: Why not?
Performance monitoring tools that are designed for a physical infrastructure use an operating system to measure and monitor the performance statistics of servers’ physical hardware. In a virtual infrastructure, the guest OS can’t see the physical hardware, only the virtual hardware that has been emulated by the hypervisor. Because an OS can’t directly access most of the host server’s physical hardware, traditional performance monitoring tools won’t function properly in a virtual infrastructure.
