Performance metrics of VMware ESX servers
The VMware ESX servers are monitored based on the parameters or the attributes listed below. These attributes provide detailed information about the functioning of the monitors of VMware ESX server. Thresholds can be configured based on these monitoring data.
A sample screenshot is also given below the table.
