Create a Custom Device Collection

As the Tools Administrator for Data Aggregator, you receive a request to monitor the performance of a new group of virtual servers. The IT Architect and Operations Center Manager want to track the CPU utilization and the memory utilization. These virtual servers host critical applications, so they want frequent updates on their status.

Note: We are assuming that you already ran an initial discovery on your network and that you have discovered some virtual servers.

You decide to first create a custom device collection to group discovered virtual servers because factory (out-of-the-box) device collections do not exist for virtual servers. To create a custom device collection, you first create a custom device collection in CA Performance Center. Automatic synchronization creates a corresponding device collection in Data Aggregator.

Follow these steps:

1. Log in to CA Performance Center as a user with the Administrator role.
2. Select Admin, Custom Settings, Groups.

   The Manage Groups dialog opens.

3. Right-click Monitored Collection and select Add New Group.

   The Add Group dialog opens. The New tab is selected by default.

4. Supply values for the following parameters:

   Group Name

   Specifies a name for the group. For this example, name the group Virtual Servers.

   Note: Do not use the following special characters in group names: /&\,%.

   Description

   (Optional) Helps you identify the group.

5. Click Save.

   The Virtual Servers group appears in the Monitored groups tree. Wait for the automatic synchronization with Data Aggregator to occur. Upon synchronization, Data Aggregator creates a corresponding device collection for use in device monitoring. Synchronization can take up to 5 minutes to begin.
