KVM Virtual Machines Test

Whenever users complain of inaccessibility of their virtual machines, administrators need to promptly determine the reason for the same - is it because the VMs are not running currently? is it because they are not even registered? or is it because they have been moved to another server? The KVM Virtual Machines test provides administrators with this information. This test tracks the status and movement of each virtual machine on the target KVM server, reports the number and names of virtual machines in various states, and also captures the migration of virtual machines to other servers.

Target of the test : A KVM server

Agent deploying the test : An internal agent

Outputs of the test : One set of results for the KVM server that is to be monitored.

Configurable parameters for the test
Parameter	Description
Test Period	How often should the test be executed.
Host	The IP address of the host for which this test is to be configured.
Port	The port at which the specified host listens.
Detailed Diagnosis	To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option. The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled: The eG manager license should allow the detailed diagnosis capability Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.

Measurements made by the test
Measurement	Description	Measurement Unit	Interpretation
Registered VMs	Indicates the total number of virtual machines that have been registered with this KVM server.	Number	The detailed diagnosis of this measure if enabled, lists each registered virtual machine, the IP address of the virtual machine and the Operating system that is loaded on the virtual machine.
Running VMs	Indicates the total number of virtual machines that are currently running.	Number	A high value is desired for this measure. The detailed diagnosis of this measure if enabled, lists each virtual machine that is currently running, the IP address of the virtual machine and the Operating system that is loaded on the virtual machine.
VMs not running	Indicates the number of virtual machines that are currently not running.	Number	The detailed diagnosis of this measure if enabled, lists each virtual machine that is currently not running, the IP address of the virtual machine and the Operating system that is loaded on the virtual machine.
Resource blocked VMs	Indicates the number of virtual machines that are currently blocked.	Number	The detailed diagnosis of this measure if enabled, lists each virtual machine that is blocked, the IP address of the virtual machine and the Operating system that is loaded on the virtual machine.
Crashed VMs	Indicates the number of virtual machines that currently crashed.	Number	Ideally, the value of this measure should be 0. The detailed diagnosis of this measure if enabled, lists each virtual machine that crashed, the IP address of the virtual machine and the Operating system that is loaded on the virtual machine.
No state VMs	Indicates the number of virtual machines that are currently holding the status ‘No state’.	Number	The detailed diagnosis of this measure if enabled, lists each virtual machine that with the ‘No state’ status, the IP address of the virtual machine and the Operating system that is loaded on the virtual machine.
Paused VMs	Indicates the number of virtual machines that are currently paused.	Number	The detailed diagnosis of this measure if enabled, lists each virtual machine that is currently paused, the IP address of the virtual machine and the Operating system that is loaded on the virtual machine.
Added VMs	Indicates the number of virtual machines that were newly added to the KVM server.	Number	This measure is a good indicator of the load on the KVM Server. The detailed diagnosis of this measure if enabled, lists each virtual machine that is added, the IP address of the virtual machine and the Operating system that is loaded on the virtual machine.
Removed VMs	Indicates the number of virtual machines that were removed from the KVM server.	Number	The detailed diagnosis of this measure if enabled, lists each virtual machine that is removed, the IP address of the virtual machine and the Operating system that is loaded on the virtual machine.
VMs with users	Indicates the number of virtual machines on which users are currently logged in.	Number	The detailed diagnosis of this measure if enabled, lists each virtual machine, the IP address of the virtual machine, the Operating system that is loaded on the virtual machine and the user who is logged into the virtual machine. Note that this measure will be available only for the KVM VDI server.
VMs without users	Indicates the number of virtual machines without any users logged in.	Number	Note that this measure will be available only for the KVM VDI server.

The detailed diagnosis of the Registered VMs measure if enabled, lists each registered virtual machine, the IP address of the virtual machine and the Operating system that is loaded on the virtual machine. This way, administrators can quickly identify the Vms that are currently registered.
