ManageEngine® Applications Manager Chapter 6.5.1 VMware ESX/ESXi Servers |
||
Supported Versions: ESX Server 3.5 and 4; ESX Server 3i
VMware ESX servers are monitored based on the parameters or the attributes listed
below. These attributes provide information about the functioning of the monitors
of VMware ESX server. You can also configure thresholds to the numerical attributes
monitored by the server based on these details.
The Availability tab shows the Availability history of the ESX server for the past 24 hours or 30 days. The Performance tab shows some key performance indicators of the ESX server such as CPU Utilization, Memory Utilization, Disk Usage and Network Usage along with heat charts for these attributes. This tab also shows the health status and events for the past 24 hours or 30 days.
The List view displays all the VMware ESX/ESXi servers along with an overall idea of their availability and health status. The list view also enables you to perform bulk admin configurations. Click on the individual servers listed to view detailed performance metrics.
The Top ESX/ESXi tab shows graphs for the top CPU consumers, top memory consumers, top disk I/O consumers and top network consumers of the ESX/ESXi server.
The Infrastructure View tab displays all the virtual machines discovered under each ESX/ESXi server. This view provides an overall idea of the availability, health, CPU (%), Memory (%), Disk I/O and Network traffic of all the virtual machines. Click on the individual virtual machines listed to view detailed VM metrics.
Click on the monitor listed in the Availability tab to view detailed performance metrics of the ESX/ESXi server. These metrics are categorized into 7 different tabs for easy understanding. Below is an explanation of the metrics shown in these tabs:
