Registering Agents on Clusters
You can streamline the process of registering agents on clusters by dening a DNS name for a cluster and
conguring that cluster so that the metrics are shared sequentially in a loop.
You only need to register the agent on the DNS, not on the IP address of each individual machine in the
cluster. If you do register the agent on each node in the cluster, it aects the scale of your environment.
When you have congured the cluster so that the received metrics are shared in a sequential loop, each time
that the agent queries the DNS server for an IP address, the returned address is for one of the virtual
machines in the cluster. The next time the agent queries the DNS, it sequentially supplies the IP address of
the next virtual machine in the cluster, and so on. The clustered machines are set up in a loop conguration
so that each machine receives metrics in turn, ensuring a balanced load.
After you congure the DNS, it is important to maintain it, ensuring that when machines are added or
removed from the cluster, their IP address information is updated accordingly.
Manually Create Operating System Objects
The agent automatically discovers some of the objects to monitor. You can manually add other objects, such
as les, scripts or processes, and specify the details so that the agent can monitor them.
The Monitor OS Object action only appears in the Actions menu of a object that can be a parent object.
Procedure
1 In the left pane of vRealize Operations Manager, select the agent adapter object that is to be the parent
under which you are creating an OS object.
2 Select Actions > Monitor OS Object.
A list of parent object context-sensitive objects appear in the menu.
3 Choose one of the following options.
n
Click an object type from the list to open the Monitor OS Object dialog for that object type.
The three most popularly selected object types appear in the list.
n
If the object type that you want to select is not in the list, click More to open the Monitor OS Object
dialog, and select the object type from the complete list of objects that are available for selection in
the Object Type menu.
4 Specify a display name for the OS object.
5 Enter the appropriate values in the other text boxes.
The options in the menu are ltered according to the OS object type that you select.
Some text boxes might display default values, which you can overwrite if necessary. Note the following
information about default values.
