Foglight for VMware Horizon View 5.6.16 - User and Reference Guide

The VMware Explorer’s Memory tab displays the combined memory utilization for an ESX host, showing the amount memory used by each virtual machine that is running on that host. This includes the amount of active and shared memory in GB, all during a selected time period.

Description of embedded views

This view is made up of the following embedded views:

•

•

•

This view shows the amounts of active memory used by each virtual machine that is running on the ESX host during the selected time period.

Shared Memory

This view shows the amounts of shared memory used by each virtual machine that is running on the ESX host during the selected time period.

Virtual Machines

This view shows a list of all virtual machines that are running on the selected ESX host. For each virtual machine, it shows its name along with a color indicator for displaying this information in the Active Memory and Shared Memory views. This allows you to show or hide the related resource use from these views.

The list also shows the following information for each virtual machine:

•

Active. Amount of physical memory that is actively being used.

•

Balloon. Amount of memory being used by the VMware® Memory Control Driver to allow the virtual machine OS to selectively swap memory.

•

Consumed. Amount of memory that is consumed by current processes.

•

Granted. Total amount of memory that is allocated to the virtual machine.

•

Shared. Amount of memory that is freed up on the host due to transparent page sharing.

•

Swapped. Amount of memory that is stored in disk swap space.

Monitor tab

This tab is available in the VMware Explorer. To find it, open the VMware Explorer and on the Virtual Infrastructure view, that appears on the navigation panel, select the server or virtual machine instance. In the VMware Explorer, open the Monitor tab.

Purpose

The VMware Explorer’s Monitor tab shows details of system resources consumption for a server or a virtual machine.

Cluster

This view shows the numbers of ESX® hosts and virtual machines the selected ESX host or virtual machine belongs to. It also shows the cluster’s combined current CPU and memory utilization along with the disk and network I/O rates, and any alarm counts associated with the cluster, broken by the alarm state.

Datacenter

This view shows the number of ESX hosts and virtual machines in the datacenter the selected virtual machine is associated with. It also shows the datacenter’s combined current CPU and memory utilization along with the disk and network I/O rates, and any alarm counts associated with the datacenter, broken by the alarm state.


	NOTE: This data only appears when exploring virtual machine details.

Host Utilizations

This view shows the utilization of the selected server’s resources. It shows the current CPU utilization for each CPU, and the composite CPU utilization across all CPUs on the selected ESX host. This view also provides insights into memory usage, and disk and network IO rates.


	NOTE: This data only appears when exploring ESX host details.

Resource Pool

This view shows the numbers of virtual machines in the resource pool the selected virtual machine is associated with. It also shows the resource pool’s combined current CPU and memory utilization along with the disk and network I/O rates, and any alarm counts associated with the resource pool, broken by the alarm state.


	NOTE: This data only appears when exploring virtual machine details.

ESX Host

This view shows the numbers of virtual machines that are running in the ESX Host to which the selected virtual machine belongs. It also shows the ESX Host’s combined current CPU and memory utilization along with the disk and network I/O rates, and any alarm counts associated with the virtual machines, broken by the alarm state.


	NOTE: This data only appears when exploring virtual machine details.

Virtual Machine Utilizations

This view shows the utilization of the resources allocated to the selected virtual machine. It shows the current CPU utilization for each allocated CPU, and the composite CPU utilization across all CPUs on the selected ESX host. This view also provides insights into memory usage, and disk and network IO rates.


	NOTE: This data only appears when exploring virtual machine details.

Virtual Machines

This view shows a list of virtual machines associated with the selected ESX host. For each virtual machine, the list shows its name, followed by the total counts of alarms associated with that VM, broken down by alarm types (normal, warning, critical, fatal). This view also indicates how many virtual machines are currently running.


	NOTE: This data only appears when exploring ESX host details.

Virtual Machine Messages

This view shows a list of messages associated with the selected virtual machine.


	NOTE: This data only appears when exploring virtual machine details.

Performance tab

This tab is available in the VMware Explorer. To find it, open the VMware Explorer and on the Virtual Infrastructure view, that appears on the navigation panel, select a Virtual Center, datacenter, cluster, ESX® host, resource pool, or one of the following containers: Datacenters, ESX Hosts, Resource Pools, or Virtual Machines. In the VMware Explorer, open the Performance tab.

Purpose and content

This tab displays the resource utilization for the selected object or group of objects over a selected period of time.

Figure 42. Performance tab

Description of embedded views

This tab is made up of the following embedded views:

•

•

•

•

•

This view shows the CPU utilization summary for the selected component based on its total capacity, including the percentage of available CPU processing that is currently used, and the percentage of time the CPU is ready but is not used due to other reasons, during a selected time period.

Disk Utilization

This view shows the disk utilization summary for the selected component, including the disk throughput rate, and the rates of data that is read from or written to the disk, during a selected time period.

Hosts

This view shows a list of all ESX hosts associated with the selected component. For each host, it shows its name, the number of CPUs, the current percentages of CPU and memory use, disk throughput rate, rate at which disk commands are issued, and the rate at which data packets are sent to and received from the network.


	NOTE: This view only appears when you are exploring virtual centers, Datacenters container, datacenters, ESX Host container, Resource Pools container, resource pools, or Virtual Machines container.

Memory Utilization

This view shows the physical memory utilization summary for the selected component, broken into the amounts of memory that is swapped to disk, actively used, and allocated, all during a selected time period.

Network Utilization

This view shows the network utilization summary for the selected component, including the average rate of network throughput, and the amounts of data sent to and received from the network.
