14.1.25 OracleVM measurement servers

The OracleVM measurement server is an active and discoverable PVSR module which can monitor the Oracle virtualization environment through the Oracle VM Manager server. The measurement server takes into account the timeout value specified for the equipment. Beside the basic attributes, the equipment has the following additional parameters (the code of the parameter is given in parenthesis; see Subsection 7.5.6 on Parameters of non-SNMP data collectors):

·       Host (ORACLEVM EQ 1 HOST): the host where the Oracle VM Manager is running. Mandatory parameter

• Port (ORACLEVM EQ 2 PORT): the listening port of the Oracle VM Manager. Mandatory parameter, its default value is 7002
• Type (ORACLEVM EQ 3 TYPE): the type of the equipment, either Server or Virtual machine. This parameter is filled in automatically during the bulk equipment discovery/creation
• User (ORACLEVM EQ 4 USER): the user used for monitoring. Mandatory parameter
• Password (ORACLEVM EQ 5 PASSWORD): password of the user. Mandatory parameter
• Item name (ORACLEVM EQ 6 OBJNAME): the name of the equipment in the Oracle VM Manager. This parameter is filled in automatically during the bulk equipment discovery/creation
• Description (Z 00 DESCRIPTION): description of the item in the Oracle VM Manager. Non-modifiable automatically discovered parameter
• Operating system (Z 01 OS): the operating system running on the equipment. Non-modifiable automatically discovered parameter
• CPU (Z 03 CPU): CPU type and speed. Non-modifiable automatically discovered parameter
• Memory (Z 04 MEMORY): configured memory. Non-modifiable automatically discovered parameter
• IP address (Z 07 IPADDR): IP addresses of the equipment. Non-modifiable automatically discovered parameter

The measurement server is able to discover the available measurements. All the possible equipments and measurements can be discovered with the use of the simple New equipment or the advanced “New equipments from template” option on the Site and equipment configuration page: the user only need to specify the connection parameters for the Oracle VM Manager and PVSR discovers all the virtual machines and host measurements, displays them in a table for the user and then create the equipments using the selected Oracle VM equipment template.

The OracleVM collector can automatically synchronize the configuration in PVSR. The synchronization is configurable with these parameters in the CONFIG_INI.pm file:

·       $PVSR_AUTO_ORACLEVM_TEMPLATE: if it is set to a PVSR equipment template and there is a new virtual machine then PVSR automatically creates it. The default value of the parameter after installation is “Default OracleVM”

·       $PVSR_AUTO_ORACLEVM_VMNAME_PREFIX: if it is set then PVSR uses its value as the prefix when automatically creating a virtual machine. The “New equipments from template” page uses this parameter as well for the same purpose. The default value of the parameter after installation is “VM ”

·       $PVSR_AUTO_ORACLEVM_VMNAME_POSTFIX: if it is set then PVSR uses its value as the postfix when automatically creating a virtual machine. The “New equipments from template” page uses this parameter as well for the same purpose. The default value of the parameter after installation is empty

·       $PVSR_AUTO_ORACLEVM_MOVE_DELETED_SITE: if it is set then PVSR moves the non-existing virtual machines into this site (next to the host equipment). If the site does not exist then PVSR automatically creates it. The default value of the parameter after installation is “Deleted”

·       $PVSR_AUTO_ORACLEVM_MANAGE_DATA_COLL: if it is set to “Y” then PVSR automatically deactivates the data collection of a virtual machine if it is not running. The default value of the parameter after installation is empty

·       $PVSR_AUTO_ORACLEVM_MOVE_OFFLINE_VM_SITE: if it is set then PVSR moves the shut-down virtual machines into this site (next to the host equipment). If the site does not exist then PVSR automatically creates it. The default value of the parameter after installation is empty

14.1.25.1 Virtual machines

This page shows the virtual machines in the virtualization environment. If the page is opened from a server then if automatically filters to show only the virtual machines on that host. If the page is opened from a virtual machines then it filters out the other virtual machines.

·       Name: name of the virtual machine

·       Status: the current status of the virtual machine

·       Server: name of the physical host running the virtual machines

·       IP address: the address of the VM

·       OS: the operating system running on the VM

·       CPU: the current and maximum number of CPUs (cores) and the CPU usage

·       Memory: the current and maximum memory

14.1.25.2 Servers

The page shows the physical hosts in the virtualization environment. The parameters for each host:

·       Name

·       Status: current status

·       IP address: the address of the server

·       CPU: CPU number and type and the CPU usage

·       Memory: the memory in the server and its usage

·       Type: the hardware type of the server

·       VM: the number and names of the VMs running on the server

14.1.25.3 Server and Virtual machine heatmap

When opened from a server the page shows all the servers in the virtual environment, when opened from a virtual machine then it shows all the virtual machines. The user can select a measurement type and specify the selected timespan with the widgets in the Time span browser area group. PVSR calculates the averages of the collected data based on these input parameters and colors the different items based on their value. The blue end of the color spectrum has the minimum value and the red end of the color spectrum has the maximum value. If an item does not have a color then it means that it does not have any collected data for the specified time span. The page also shows the actual time span for which there is collected data in the system.
