ManageEngine® Applications Manager VMware ESX/ESXi Servers | ||
Supported Versions: ESX 3.5 and above; ESXi 3 and above.
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.

8) Storage
Applications Manager automatically maps VMware vSphere servers and their VMs to their underlying physical storage arrays. To perform VM-to-storage mapping, you must first integrate Applications Manager with Opstor.
You can track the vSphere servers and their VMs to the datastores, to the host bus adapters and the actual physical storage. This tab displays:
A storage map combining Applications Manager's application and VM performance data with OpStor's storage performance data.
A storage mapping table displaying Virtual Machine, Datastore, Storage Array and corresponding LUN statistics.

| Fan | Sensor Reading will be monitored in percentage |
| Temperature | Sensor Reading will be monitored in Degree Celsius |
| Processors | Health status of the sensor will be monitored. |
| Memory | Health status of the sensor will be monitored. |
If a component is functioning normally, the status indicator is green.
The status indicator changes to orange or red if a system component violates a performance threshold or is not functioning properly. Generally, an orange indicator signifies degraded performance.
A red indicator signifies that a component stopped operating or exceeded the highest threshold.
If the status is blank, then the health monitoring service cannot determine the status of the component.
The Reading column displays the current values for the sensors. For instance, the column displays watts consumed for System Board and degrees Celsius for temperature.
