Alarming with Tree Control hierarchy

David Merrifield [DevOps Advocate]769 8th October 2025 0 Comments

HI All,

I'm working with Tree Control UI component and need some guidance on enabling alarms to propagate up the hierarchy. For instance, when an alarm occurs on a lower level node (as shown in the example below), it doesn't appear visible at the top level unless I manually expand the entire tree structure. From what I understand, implementing Alarm Bubble Up should address this by surfacing the alarm to parent nodes automatically?? I've reviewed the documentation here:https://docs.dataminer.services/develop/devguide/Connector/UIComponentsTreeControl.html can you confirm if that's the right approach, and if not, what is?

Thanks,

Dave

Update:

Quick update. Seems to have worked for me but it appears all the Statistics parameters have gone into alarm for that single device even though its just a PS Status alarm.

Second update

I get the following now using the following alarm Template settings to cause a fake alarm.

Hi David,

it should work, if you defined a relation for it: Alarm bubble-Up | DataMiner Docs

Eventually you need to disassign/assign the alarm template (or enable/disable the specific alarm in the template) again to updte the alarm tree/see the results.

Best regards,

Felix

Hi Felix, Just posted an update. Appears to have work but getting alarms on everything.

Felix Wesemeier [DevOps Catalyst] commented 8th October 2025

Hi David, this should not be the case. would you like to show your alarm template?

David Merrifield [DevOps Advocate] commented 8th October 2025

Thanks Felix, I've just updated the ticket with more information.

Felix Wesemeier [DevOps Catalyst] commented 10th October 2025

Hi David,
now I understood you have multiple treeviews and you use the same table as your "root table" everytime.
Never tried it this way, so I'm not sure if it should work.
Did you define a unique name for each topology?
<Relation path="100;200" options="includeInAlarms:topology1"/>
<Relation path="100;300" options="includeInAlarms:topology2"/>

Apologies for the late response. That is correct. I do define unique names for each topology. What would be the correct way to do this?
