VMware ESX server hosts multiple server instances on a single host machine. Each instance functions as an individual server component and can host applications. The server instances on the VMware ESX can have different OS and each instance is monitored by OpManager for availability and performance. Using OpManager, you can monitor the entire VMware ESX server unit and also each instance within for clear visibility into its performance, the monitored versions being ESX version 3 or higher.
Availability & Performance: Besides monitoring the availability of the VMware and its individual intances, you can also closely monitor the performance of the resources on each instance like the CPU, Memory, and if the allocated resource for each instance is utilized optimally. Intuitive dashboard graphs for the server farm helps you quickly identify if the resources are over-utilized or under-utilized.

OpManager aids you in optimizing productivity by monitoring the availability of resources on the host. It is also that your server's capacity is very much under-utilized. A snapshot view of the VMware in OpManager, helps in quick decision making and levering the resources optimally.
