Administering monitored ESX hosts and virtual machines

A VMware® environment typically includes one or more Virtual Centers. A Virtual Center includes a collection of datacenters, clusters, ESX® hosts, resource pools, and virtual machines. Data centers are typically used to define physical boundaries within which ESX hosts exist, while resource pools enable an administrator to fine-tune resource allocations within a cluster. A cluster can have one or more ESX hosts associated with it, and one or more virtual machines can run on each ESX hosts. Each virtual machine is allocated a portion of the ESX host’s resources, including disk, CPU, memory, and network resources. A virtual machine has its own machine name and IP address, and it runs a guest OS (for example, MS Windows XP), along with other applications.

Additionally, VMware implements the concepts of virtual machine snapshots and ESX host workflows. A virtual machine snapshot is a virtual machine image that you can return to at any point in time. A workflow, on another hand, is a way to automate ESX host tasks, and re-run them using a different set of parameters. For example, you can use an existing virtual machine creation task, change some of its resource allocation parameters, and run it again.

These actions require that you set up credentials for the virtual center on the Automation Configuration dashboard. To do that, on the navigation panel, under Dashboards, choose VMware > Automation Configuration. On the Automation Configuration dashboard that appears, in the Virtual Infrastructure view, select a virtual center, click Assign Credential, and provide host credentials in the Assign Host Credentials Dialog box. Failing to configure host credentials results prevents the automated tasks from being executed.

The VMware Explorer’s Administration tab provides access to most of these administration tasks. Use it to shut down or reboot physical ESX hosts and virtual machines, or to create virtual machines and edit their resource allocation. This tab also provides quick access to creating and editing virtual machine snapshots and ESX host workflows.

To open the VMware Explorer’s Administration tab for an ESX host or virtual machine object instance:
1
Log in to the Foglight browser interface.
2
Ensure that the navigation panel is open.
To open the navigation panel, click the right-facing arrow on the left.
3
On the navigation panel, under Dashboards, choose VMware > VMware Explorer.
The VMware Explorer appears in the display area, with the Summary tab open.
4
On the navigation panel, under Virtual Infrastructure, on the Topology tab, select an ESX host or virtual machine object instance in the navigation tree.
5
In the VMware Explorer, open the Administration tab.
This image illustrates the content of the Administration tab when exploring ESX host details.
When you select a virtual machine in the VMware Explorer, a slightly different set of tasks appears.
