The VCAP4-DCA is directed toward System Administrators, Consultants and Technical Support Engineers who can demonstrate their skills in VMware vSphere and VMware vCenter technologies in relation to the datacenter, as well as their knowledge of application and physical-infrastructure services and their integration with the virtual infrastructure.
The VCAP-DCD is directed toward IT Architects and Consulting Architects who are capable of designing VMware solutions in a multi-site, large enterprise environment. They have a deep understanding both of VMware core components and their relation to storage and networking, and also of datacenter design methodologies. They also possess knowledge of applications and physical infrastructure, as well as their relationship to the virtual infrastructure.

Zenoss has announced that it is now offering a free ZenPack for monitoring the performance of VMware ESX/ESXi servers. Similar to the Unix "Top" command, this ZenPack uses the VMware resxtop command to aggregate and alert on performance metrics in a single graphical view in order to provide administrators an expanded and deeper VMware ESX/ESXi monitoring experience. With this ZenPack, Zenoss is the first to enable proactive VMware management using esxtop.
VMware’s esxtop is a very powerful VMware administrator’s tool used to obtain a snapshot of the current server state. It not only provides metrics but give you visibility to issues such as disk latency, CPU contentions, memory over commits, etc. VMware administrators have until now used esxtop at the command line to access host server performance metrics.
Virtualization administrators, while enjoying the power of the esxtop command, have been looking for enhancements to help simplify and improve performance troubleshooting. Currently the command must be executed through the command line interface and provides no capability for reporting or alerting. Historical data analysis and graphing requires users to manually redirect data to a file for further offline analysis and charting.
The new ZenPack for esxtop enables the following:
• Performance metrics from ESX and ESXi servers are automatically captured, graphed, displayed, and continually updated in one graphical interface.
• Users can set thresholds and exception alerting based on performance metrics and events as they occur.
• Historical data is saved for in-depth root cause analysis.
“As we have been working with organizations to provide deep VMware monitoring capabilities, we saw some of our customers and community members using the esxtop command. Unfortunately, this tool was somewhat hidden and only available for power users. We are combining the strength and ease of use of Zenoss with the esxtop command to provide a simpler monitoring capability for VMware ESX environments,” said Simon Jakesch, Engineer at Zenoss. “With this free ZenPack, users can easily identify performance problems in their ESX and ESXi environment, and immediately take steps to resolve the issues before they affect the business. This capability will save administrator time and increase accessibility to a very powerful performance tool.”
ZenPacks are software extensions to Zenoss. The ZenPack for esxtop is free. For more information on how to download the ZenPack, visit the Zenoss blog.

After installing the Symantec ApplicationHA Console it’s time to roll out the Symantec ApplicationHA Guest components. You can use a wizard to configure monitoring for applications, services, and processes running on virtual machines. After completing this wizard, you can start, stop, and monitor the configured components from the VMware vSphere Client or using Microsoft Internet Explorer.
You can also perform the application monitoring operations directly from a browser window using the following URL: Https://<virtualmachineNameorIPaddress>:5634/vcs/admin/application_health.html?priv=ADMIN To view the Symantec ApplicationHA view, launch the VMware vSphere Client, select a virtual machine from the Inventory pane, and in the Management pane on the right, click the ApplicationHA tab. If you have not configured single sign-on for the virtual machine, specify the user credentials of a user that has administrative privileges on the virtual machine.
If a component fails, a configurable number of attempts are made to restart it on the machine. If the component does not start, the virtual machine itself can be restarted by VMware HA, depending on the configuration settings.
It’s also possible to configure application monitoring for custom services, processes, and storage mount points on a virtual machine. You can either choose one or multiple components simultaneously.
- Configure multiple services and processes in a single wizard workflow
- Configure storage monitoring to control storage availability on the virtual machine
- Configure dependency to control orderly start and stop of components
In this example I’ve chosen to configure application monitoring for Microsoft SQL Server 2008 instances running on a virtual machine. Now I’m able to:
- Monitor SQL Database Engine service, Analysis service, and FILESTREAM
- Monitor and control the availability of SQL databases on the virtual machine
- Perform a graceful start and stop of SQL services and databases
Symantec ApplicationHA provides an interface, the Symantec ApplicationHA tab, to configure and control application monitoring. The Symantec ApplicationHA tab is integrated with the VMware vSphere Client. Use the Symantec ApplicationHA view to perform the following tasks:
- Configure and unconfigure application monitoring
- Start and stop configured applications
- Enable and disable application heartbeat
- Enter and exit maintenance mode
