A dashboard user can click a shape in the dashboard at run time and navigate to a diagram associated with another monitoring context or key performance indicator (KPI) context. You can either set the link to work only if the value of a metric or KPI matches a certain expression, or set the link to go to different diagrams based on the value.
In the Monitor Model editor, when you are testing the links, the linked diagram will use any test values that you added to its associated context. If these are metric test values, you can think of them as representing metrics for a single test instance.
In the dashboards, you can view a monitoring context diagram either with or without instance annotations. From Instances in the dashboards, you can pick a particular instance and show the diagram specific to that instance, in which case the diagram is annotated with the metric values for that instance.
If the monitoring context diagram in the dashboard IS NOT annotated for a specific instance, linking to another monitoring context diagram will result in the display of a generic linked monitoring context diagram (one that is also not annotated for a specific instance). If the monitoring context diagram in the dashboard IS annotated for a specific instance, the link must be to a child monitoring context. If the current instance has one or more child instances, the linked diagram will be annotated with the values from the first of those child instances.
Regardless of whether the monitoring context is annotated for a specific instance, you can always link to a KPI context diagram (which is annotated by default in the dashboards). You can also add a link from a KPI context diagram to a monitoring context diagram. In the dashboards, the linked monitoring context diagram will not be annotated for a specific instance, since there is no current instance on which to base the annotations.
To link from one diagram to another diagram, complete the following steps:
