I have a service table containing my services and a lot of tables that are linked through FK linking to my service table. I would like to see the aggregated alarm state of a service over all my tables. So if an alarm template is configured to generate an alarm on for example the Program or PID table, it should be reflected on the aggregated service state. Would it be possible to do this in Visual Overview without the need to create services?
I believe the server already provides this when having the structure as a tree control. Each level in the tree view then has access to the bubble up info coming from its children. This info contains the highest bubble up severity. However, you can't access or display this info yet on the Visual Overview (that would make a nice new feature though).
Indeed, this would be a very helpful feature.
Is this already on roadmap, or are there any workarounds suggested?
As indicated by Sebastiaan you can use the TreeControl option to bubble up the severity. You could try to display this in Visio through the parameter control option: https://help.dataminer.services/dataminer/#t=DataMinerUserGuidepart_2visioTurning_a_shape_into_a_parameter_control.htm
You can find the TreeControl parameter in your driver:
…
<TreeControl parameterId="500" …
If you are interested in adding a TreeControl into a driver you created you can check the following video (part of our driver development training):
