Virtual Network Traffic - VM Test

OLVM Manager supports multiple virtual networks and VLANs, allowing an administrator to centrally manage and configure the virtual network. Virtual networks emulate network connectivity within the Oracle VM server and allow VMs hosted on that server to exchange data. Continuous monitoring of these virtual networks will enable administrators to isolate which virtual networks are healthy and are too busy trafficking data to and from VMs, and which virtual networks are experiencing error conditions. The Virtual Network Traffic - VM test does just that.

Target of the Test: An Oracle VM Server 4.x

Agent running the test: A remote agent

Output of the test: One set of results for every virtual network on the Oracle VM Server being monitored.

Configurable parameters for the test
Parameter	Description
Test period	How often should the test be executed.
Host	The host for which the test is to be configured.
Management Server Host IP, Management Server Domain, Management Server Port, Management Server User, Management Server Password	To auto-discover the VMs on a target Oracle VM Server 4.x and obtain the outside view of the performance of each VM, the eG agent needs to connect to the OLVM Manager that manages the target Oracle VM Server 4.x. To enable the eG agent to obtain the outside view, you need to configure the test with the following: Management Server Host IP - The IP address/host name of the OLVM manager that the eG agent should connect to. Management Server Port - The port number at which the said OLVM manager listens. Management Server Domain - The domain to which the OLVM manager belongs. Management Server User, Management Server Password - The credentials of a user with read-only access to the Restful API on the OLVM manager . To know how to create a read-only role and assign it to a user, follow the steps detailed in Configuring the eG Agent to use the RESTful APIs on the OLVM Manager to Obtain the “Outside View”. If the Oracle VM server being monitored was discovered via an OLVM manager , then the IP address, port number, domain name, and user credentials of the OLVM manager used for discovery will be automatically displayed against the respective parameters. If the Oracle VM server being monitored was not discovered via an OLVM manager , but you still want to use an OLVM manager for obtaining the outside view, then, you can select any IP address of your choice from the Management Server Host IP list. By default, this list will be populated with the IP addresses/host names of all the OLVM managers that were configured for the purpose of discovering the Oracle VM servers. If you select an Management Server Host from this list, then the corresponding port number, domain name, and user credentials will be automatically displayed against the respective parameters. On the other hand, if the OLVM manager that you want to use for metrics collection is not available in the Management Server Host list, then, you can configure an OLVM manager on-the-fly by picking the Other option from the Management Server Host list. An ADD THE OLVM MANAGER DETAILS window will then pop up. Refer to Configuring an OLVM Manager to Use for Monitoring the Oracle VM Server 4.x to know how to add an OLVM manager using this window. Once the OLVM manager is added, its IP address, port number, domain name and user credentials will be displayed against the corresponding parameters.
Confirm Password	Confirm the Management Server Password by retyping it here.
SSL	If the OLVM manager to which the eG agent should connect is SSL-enabled, then set this flag to Yes. If not, set it to No.

Measurements made by the test
Measurement	Description	Measurement Unit	Interpretation
Network data transmitted	Indicates the rate at which data is transmitted over this virtual network.	Mbps	A high rate of incoming and outgoing data could indicate that the virtual network is very busy or is been overloaded with traffic.
Network data received	Indicates the rate at which data is received over this virtual network.	Mbps
Errors during transmission	Indicates the number of errors that occurred when data was transmitted over this virtual network.	Number	Ideally, the value of both these measures should be 0. Comparing the value of each of these measures across virtual networks will introduce you to the error-prone networks.
Errors during reception	Indicates the number of errors that occurred when data was received over this virtual network.	Number
