Hello and welcome. This presentation provides a brief demonstration of the Oracle Linux
Virtualization Manager monitoring features introduced in Oracle Enterprise Manager 13.4.
In this session, I'm logged in as a cloud administrator. The interface displayed is
the Oracle Linux Virtualization Manager Infrastructure Cloud home page.
This interface provides the highest level view of the virtualization environment configured
with one or more instances of the Oracle Linux Virtualization Manager.
This interface is similar to the Oracle VM Manager Infrastructure Cloud home, providing
an overview of the configuration and consumption of resources.
The General panel provides a quick status view of all targets managed by Oracle Enterprise
Manager. The numbers by each of the labels in this panel are links to lists of the respective
targets. These targets are arranged in hierarchical order consistent with the Oracle Linux Virtualization
Manager configuration.
This infrastructure home manages two Oracle Linux Virtualization Manager instances, with
two total data centers containing 3 clusters, running on four servers and hosting 16 VMs.
The Inventory and Usage panel provides a fast and flexible way to know how many servers
or guest VMs are running at different levels in the configuration hierarchy.
The display currently shows the number of guest VMs hosted and managed in each of the
two Oracle Linux Virtualization Managers in this infrastructure configuration.
Click the first Show input and change select servers and the display changes to show servers
in each virtualization manager. Click the second input, and you see that in addition
to the hierarchical configuration option, there are options based on Oracle Enterprise
Manager like cost center and owner. Click on Cluster, and see that the cluster names
are now displayed.
The target flux panel shows the numbers of guest VMs deployed and retired for the last
30 days.
The CPU panel provides a graph of CPU Utilization for the entire configuration. This particular
configuration is a lab environment and is somewhat lower than could be expected with
a production environment.
The Memory panel provides an overview of memory consumption across the infrastructure configuration.
The overview of incidents and problems provides a summary of faults, failures, or other events
of interest. The Oracle Enterprise Manager incident management framework allows you to
create custom incident rules based on various aspects of operation. For more information,
see the presentation titled "Creating an Incident Rule to Report an Oracle Linux Virtualization
Manager Service Failure."
Click on the menu at the top of the page. Among the options here is one to register
an Oracle Linux Virtualization Manager into the infrastructure cloud. For more information
on this feature, see the presentation titled "Registering Oracle Linux Virtualization Manager
with Oracle Enterprise Manager."
Click on the infrastructure cloud menu again and click Home.
Click on the number link next to the Guest VMs label in the General panel to display
a list of all guest VMs in this configuration. The list of guest VMs provides status, target
type, hosting server and Operating System, and memory and number of CPUs. A link to display
utilization is also provided.
Now, click on the target name of a guest VM to display the target home interface.
Oracle Enterprise Manager displays a lot of guest VM details. And, in the General panel,
you see the managed targets in its hierarchy, including Server, Cluster, Data center, virtualization
manager, and host.
Details about the VM itself appear in the Configuration panel, including CPU, memory
and related information.
Click on the Guest VM menu to see the various kinds of management activities and controls
provided by Oracle Enterprise Manager.
Move up the configuration hierarchy by clicking the name of the server displayed in the General
panel.
The virtualization server target home interface appears. The general panel includes links
to other objects in the hierarchy like cluster and data center. The hardware panel provides
details about the server hardware and architecture. The software panel provides details about
the operating system and important software hosted.
CPU and memory utilization are shown in the upper right panel, and network activity appears
below that.
Open the server target menu, navigate through Monitoring, and click All Metrics.
The display that appears shows all metrics collected on the operation of the server.
For example, click on load to see how the server load is measured. The values include
CPU utilization, available memory, memory utilization, and number of guest VMs.
Tabs on the interface provide access to deeper information by listing any metric events that
might have been detected, and providing an overview of the metric collection schedule.
Oracle Enterprise Manager provides features that allow you to create metric extensions
to measure custom operational aspects or monitor custom features. For more information, see
the presentation titled "Configuring an Oracle Enterprise Manager Metric Extension for Oracle
Linux Virtualization Manager."
Return to the server menu, and click Home.
After the server target home interface appears, click the cluster name in the general panel.
The cluster target home interface is now displayed. The general tab provides an overview of the
cluster. Here, you see a cluster-wide perspective on CPU and memory utilization. The general
panel for the cluster displays attributes of all servers. In this demonstration, there
is only one server in the cluster, which is a default configuration when first installing
Oracle Linux Virtualization Manager.
To get another look at the configuration, click on the tab to open the target navigation
menu on the interface.
Click on the infrastructure cloud at the top, and see there are two Oracle Linux Virtualization
Managers. This is an example of the single pane of glass advantage to using Oracle Enterprise
Manager to simultaneously monitor multiple Oracle Linux Virtualization Manager instances.
Click on the ICD_OLVM to display data centers. If you become confused about which objects
are displayed in the tree, hover the cursor over the icon in the tree entry to see a pop
up label, for example Oracle Linux Virtualization Manager, and - after expanding the manager
- see the Oracle Linux Virtualization data center. Expand the cluster to see the server
and non-running guest VMs.
Now, click on the data center entry to see the data center home interface.
The data center home interface appears. As with other, similar home interfaces, you see
CPU and Memory utilization information, and the general panel provides status for VMs,
servers and clusters the configuration hierarchy.
Navigate to the ICD_OLVM virtualization manager home by opening the target navigation interface
and clicking its entry in the target navigation tree.
With Oracle Enterprise Manager 13.4, you can only monitor, but not configure, storage and
networks in the Oracle Linux Virtualization Manager Infrastructure Cloud.
Open the target navigation menu and navigate through Administration and click the Storage
option. The storage interface appears, and here, the Disks tab is displayed. You can
see all the disks which have been configured for guest VMs.
Click the Volumes tab and see that currently that are not storage volumes configured. and
Click the Domains tab to see configured storage domains.
Return to the Oracle Linux Virtualization Manager target menu, navigate through Administration
and click Network.
The network interface appears with a list of configured networks. Click the vNIC profiles
tab to see the vNIC profiles configured.
Open the target navigation interface and click on the entry at the top to return to the Oracle
Linux Virtualization Manager Infrastructure Cloud home interface.
In this demonstration, you were given an overview of the various target monintoring and related
interfaces in Oracle Enterprise Manager for monitoring Oracle Linux Virtualization Manager.
This ends the presentation. Thank you for watching.
