A VM with 100% CPU usage is fine if the host has capacity. A VM with 10% CPU usage but high CPU Ready Time is a problem. Ready Time measures contention. If this is high, you need to migrate VMs to another host or add physical CPUs.
XenServer (now known as ) is a leading server virtualization platform based on the Xen Project hypervisor. Like any critical infrastructure layer, ensuring its health and performance is vital. Effective monitoring moves beyond simple "up/down" status checks; it provides visibility into resource contention, capacity planning, and the root causes of performance degradation. xenserver monitoring
