Monitoring virtualization targets in Oracle Enterprise Manager 12C

Contributed by Sampanna Salunke, Principal Member of Technical Staff, Enterprise Manager

For monitoring any target instance in Oracle Enterprise Manager 12C, you would typically go to target home page, and click on the target menu to navigate to:

  • Monitoring->All Metrics page to view all the collected metrics
  • Monitoring->Metric and Collection Settings to set thresholds and/or modify collection frequencies of metrics
The thresholds and collection frequencies modified affect only the target instance that you are making changes to.

However, some of virtualization targets need to be monitored and managed differently due to changes made to the way data is collected and thresholds/collection frequencies are applied. Such target types include:

  • Oracle VM Server
  • Oracle VM Guest

As an optimization effort to minimize number of connections made to Oracle VM Manager to collect data for virtualization targets, the performance metrics for Oracle VM Server and Oracle VM Guest targets are “bulk-collected” at the Oracle VM Server Pool level. This means that thresholds and collection frequencies of Oracle VM Server and Oracle VM Guest metrics need to be set on the Oracle Server Pool that they belong to. For example, if a user wants to set thresholds on the “Oracle VM Server Load:CPU Utilization” metric for Oracle VM Server target, the sequence of steps to be performed are:

1. Navigate to the homepage of the Oracle VM Server Pool target that the Oracle VM Server target belongs to

2. Click on the target menu->Monitoring->Metric and Collection Settings


3. Expand the view option to “All Metrics” if required, and find the “Oracle VM Server Load” metric and change the thresholds or collection frequency of "CPU Utilization" as required.


Note that any changes made at the Oracle VM Server Pool for a “bulk collected” metric affect all the targets for which the metric is applicable in the server pool. In this example, since the user modified the “Oracle VM Server Load: CPU Utilization” threshold, the change is applied to all the Oracle VM Server targets in the server pool sg-pool1.

To summarize – the differences between “traditional” monitoring and “bulk-collected” monitoring is that the thresholds and collection frequencies of metrics are modified at the parent target, and the changes made are applied to all the children targets for which the metrics are applicable. However, data and alerts uploaded continue to appear as normal against the child target.

New and updated Oracle Enterprise Manager 12c Plug-Ins for Infrastructure as a Servce ( IaaS )

With the recent announcement of Oracle Enterprise Manager 12c Release 2 Plugin Update 1 (12.1.0.2), building and managing Infrastructure as a Service ( IaaS ) cloud is simpler than ever. Enterprise Manager for Oracle Virtualization (VT) plug-in 12.1.0.4 now support Oracle VM 3.2.1 which is enhanced for building much more secure and scalable enterprise class infrastructure cloud. Particularly, we were able to see significant performance improvement in handling parallel operations in the area of storage and VM management. Some of the key features supported for Oracle VM 3.2.1 include:

• Virtual Machine Tagging- During deployment, users specify tags (that can be edited later) for the machines they are creating, and search based on the tags.

• Periodic Storage Repository Refresh - Synchronization between data on the repository and that on the Oracle VM Manager can now be automated

• Oracle VM Agent password update support - Oracle VM Agent password can now be updated via the EM UI

• Virtual Server Roles support – Servers can be marked for playing different roles, such as utility role or virtual machine role

• VM start policy – Users can set the policy on where the VM should be started on (e.g., Current Server, Best Server or based on Pool Policy)

• OCFS2 timeout support – Users can set heartbeat timeout for servers in a clustered server pool

More details on Oracle VM 3.2.1 features can be found here

Enterprise Manager for Oracle Cloud (SSA) 12.1.0.5 enables the new capabilities provided by Enterprise manager for Oracle Virtualization plug-in 12.1.0.4 for self service users through self service portal.

Some of the key features and improvements in Enterprise Manager for Oracle Virtualization 12.1.0.4 and Enterprise Manager for Cloud 12.1.0.5 plug-ins for building Infrastructure as a Service cloud include:

• Faster and consistent synchronization with Oracle VM Manager – Any VM status change is reflected in Enterprise Manager must faster than before and more consistently. Both target status and OVM status of VM target instance in EM are consistently updated when VM goes through any status changes

• Improved UI page performance – Many of key UI pages for cloud management load much faster now

• Improved assembly deployment – There are multiple enhancements in this area including better error handling, improved and more robust Storage Repository selection for better distribution on storage usage, and enhanced network placement logic.

• Out of box assembly support - Database assemblies available in Self Update Console can be downloaded and used in Self Service Portal for easy deployment of database in your cloud. Deployment is completely integrated with EM agent deployment so that host and applications like database instance can be discovered and managed when the assembly deployment is complete

Follow the steps below to enable the latest functionality using these plug-ins:

1.    Apply patchset update (PSU) patch 14840279 to EM 12c Release 2 (12.1.0.2) OMS $ORACLE_HOME. This is a recommended patch on 12.1.0.2.0
2.    Deploy the Oracle Virtualization Plug-in 12.1.0.4.0 and Oracle Cloud Plug-in 12.1.0.5.0 on the OMS using the Enterprise Manager 12c console. If you plan to use the database assemblies, also deploy the Oracle Database Plug-in 12.1.0.3.0

To deploy the above three plug-ins use the following EM CLI command:

$ emcli login -username=sysman -password=<password>
$ emcli deploy_plugin_on_server -plugin="oracle.sysman.vt;oracle.sysman.ssa;oracle.sysman.db"

3.    Apply the Virtualization Plug-in patch 16235354 on to the Plug-in $ORACLE_HOME. (Make sure PSU mentioned in step 1 is applied before this step.)
4.    Deploy the Oracle Virtualization 12.1.0.4.0 Plug-in on the Enterprise Manager Agent managing Oracle VM Manager using the Enterprise Manager console. (This is the agent used when registering the OVM Manager to Cloud Control)
5.    Apply patch 16219750 on this same Agent used to manage the Oracle VM Manager target. This can be done via a Patching Plan in the Enterprise Manager Console.
6.    Apply the Virtualization Plug-in patch 16235337 on the Agent. (Make sure patches mentioned in steps 3 and 5 are applied before this step - this can also be applied via a Patching Plan)

Refer to support note 1371536.1 for more details.

Best Practices for Building a Virtualized SPARC Computing Environment

Oracle recently published Best Practices for Building a Virtualized SPARC Computing Environment, a white paper that provides guidance on the complete hardware and software stack for deploying and managing your physical and virtual SPARC infrastructure. The solution is based on Oracle SPARC T4 servers, Oracle Solaris 11 with Oracle VM for SPARC 2.2, Sun ZFS storage appliances, Sun 10GbE 72 port switches and Oracle Enterprise Manager Ops Center 12c. The paper emphasizes the value and importance of planning the resources (compute, network and storage) that will comprise the virtualized environment to achieve the desired capacity, performance and availability characteristics.

Please join us for Oracle Enterprise Manager Ops Center Customer Community call on Thursday, October 25 at 8AM PT, 11AM ET.  to learn more about the best practices for building a Virtualized SPARC Computing Environment and ask any questions you may have.

The document also details numerous operational best practices that will help you deliver on those characteristics with unique capabilities provided by Enterprise Manager Ops Center including policy-based guest placement, pool resource balancing and automated guest recovery in the event of server failure. Plenty of references to supplementary documentation are included to help point you to additional resources. Whether you’re building the first stages of your private cloud or a general-purpose virtualized SPARC computing environment, these documented best practices will help ensure success.
