Working with collection views and viewlets
Each collection view contains one or more viewlets. There are three types of viewlets: resource, standard, and view panel.
Resource viewlets
A resource viewlet is specific to a single instance of a resource. In Figure 3–2 each viewlet shows information about the Backorders database resource.

Standard viewlets
A standard viewlet is predefined by OpenEdge Management for displaying content from multiple resources or other aspects of OpenEdge Management.
Figure 3–3 shows a viewlet consisting only of active monitoring plans.

Other standard viewlets that OpenEdge Management provides are as follows:
- Collection members — A list of all members of the collection, including other collections. A description of the member also appears, if available.
- Active monitoring plans — A list of all active resource monitoring plans.
- Running reports — The reports currently running shown in tabular format. You can customize the view by selecting the fields to display in each report.
- Alert severity legend — An explanation of the various icons used to indicate the severity of an alert.
You can customize the view by selecting the fields to display for each resource.- Resources with alerts — A list of resources with open alerts as well as summary information, such as the date and the time of the last occurrence. Each resource name is preceded by its container name.
- Running jobs — The jobs currently running shown in tabular format. You can customize the view by selecting fields to display for each job, or by limiting the display to jobs running longer than some period of time.
- Resource status legend — An explanation of what certain data in the viewlet represents.
View panel viewlets
A view panel viewlet displays a view for any other collection being referenced by the active collection. Your ability to define views in one collection that you can display in another collection contributes to centralized, streamlined maintenance. This ability also eliminates the need for creating duplicate viewlets of the same data.
Figure 3–4 shows the sampler view in the My Collections.Home.DBs collection. The sampler view contains viewlets showing the members of the DBs collection, any resources with alerts, any running jobs, and any running reports.
