ManageEngine® Applications Manager Virtual Machines | ||
The virtual machines(VMs) present in a VMware ESX/ESXi server are monitored based on the parameters or the attributes listed below. These attributes provide information about the functioning of the VMs. You can also configure thresholds to the numerical attributes of the VMs based on these details.
The Availability tab lists all the virtual machines present in the VSX/VSXi servers and their availability status. You can also view Availability history of the virtual machines for the past 24 hours or 30 days. The Performance tab shows some key performance indicators of the virtual machine including CPU Utilization, Memory Utilization, Disk I/O Utilization and Network Utilization 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 virtual machines discovered under each VSX/VSXi server. This view provides an overall idea of the availability and health of all the virtual machines. The list view also enables you to perform bulk admin configurations. Click on the individual virtual machines listed to view detailed VM metrics.
The Top Virtual Machines tab shows graphs for the top CPU consumers, top memory consumers, top disk I/O consumers, and top network consumers of the VSX/VSXi server. This section enables you to find out which virtual machines are consuming your server resources and take action accordingly.
Click on the individual monitors listed in the Availability tab to view detailed performance metrics of the corresponding virtual machine. These metrics are categorized into 6 separate tabs for easy understanding. Below is an explanation of the metrics shown in these tabs:
1) Overview
This tab provides a high-level overview of the virtual machine as well as its resource utilization.
| Parameter | Description |
|---|---|
| Monitor Information | |
Name |
The name of the virtual machine |
Type |
Denotes the type you are monitoring. |
Health |
Denotes the health (Clear, Warning, Critical) status of the VM. |
Last Polled at |
Specifies the time at which the last poll was performed. |
Next Poll at |
Specifies the time at which the next poll is scheduled. |
| Availability | Shows the current status of the VM - available or not available. |
| CPU & Memory Utilization | |
| CPU Utilization | The CPU Usage of the VM as percentage |
CPU Usage |
The CPU usage in Mega Hertz |
Memory Utilization |
The memory utilization of theVM in percentage |
| CPU Ready |
The percentage of time that the virtual machine was ready, but could not be scheduled to run on the physical CPU (ms) |
| CPU Wait | Total CPU time spent in wait state (ms) |
| Disk & Network Usage | |
Disk I/O Utilization |
The disk input/output utilization of the VM(kbps) |
| Network Utilization | The network usage of the VM in kbps |
2) Memory
This tab shows metrics about the memory utilization of the virtual machine
| Parameter | Description |
|---|---|

Amount of memory that is actively used, measured as recently touched pages(MB) |
Overhead Memory |
Amount of additional host memory allocated to the virtual machine. |
| Swapped Memory | Amount of memory that is swapped. |
| Shared Memory | Amount of memory that is shared between virtual machines. |
| Ballooned Memory | Amount of memory held by memory control for ballooning. |
| Granted Memory | Amount of physical memory granted. For hosts this can be represented as regions of memory for each virtual machine. |
3) Datastore
| Parameter | Description |
|---|---|
Datastore |
Name of the datastore |
Type |

| Used GB | The used space of this datastore in giga bytes |
| Free GB | The free space of this datastore in giga bytes |
| Utilization % | Percentage of used space in this datastore |
| Free Space % | Percentage of free space in this datastore |
| Health | Overall health of the datastore |
| Read Rate | Rate of reading data from the datastore (kbps) |
| Write Rate | Rate of writing data to the datastore (kbps) |
| Read Latency | The average time a read from the datastore takes (ms) |
| Write Latency | The average time a write to the datastore takes (ms) |
4) Network
The metrics in this category contain the VM network status details.
| Parameter | Description |
|---|---|
Network Interface |
|
Name |
Name of the Network Interface Card (NIC) |
| IP Address | The ip address of the NIC |
| Mac Address | The Mac address of the NIC |
| Network | The name of the network |
| Health | Indicates the health of the Network Interface Card |
| Network Interface Utilization | |
| Name | Name of the network inteface card(NIC) of the host |
| Data Receive Rate | The rate at which this NIC receives data(KBps) |
| Data Transmit Rate | The rate at which this NIC transfers data (KBps) |
| Packets Received | Number of network packets received by this NIC |
| Packets Transmitted | Number of network packets transmitted by this NIC |
| Health | Overall health of this NIC |
5) Disk
This tab shows detailed disk stats of the virtual machine
| Parameter | Description |
|---|---|
LUN |
Logical unit number associated with the physical disk |
Disk Read Rate |
Disk read rate of this LUN(KBps) |
| Disk Write Rate | Disk write rate of this LUN(KBps) |
| Disk Reads | Number of reads to this LUN during the defined interval |
| Disk Writes | Number of writes to this LUN during the defined interval |
| Health | Overall health of this LUN |
| Commands Aborted |
