Hi,
we need to get the name of an event (using Analytics builder or EPL, it doesnt matter)
usually in the event documentation below, .source is the cumulocity internal ID of the device and not its name:
while in the web interface i can see the name of the device in the event details
so how can we retrieve this name via analytics builder (ex: using extract property) or via EPL? is it possible? and if yes, which property path name we should use?
An event does not have any name just text. Are you referring to the name of the device the event is created for?
If so I think you need to do a managed object query with the provided source ID to retrieve the device name.
Check out the example in the documentation:
Hi Stefan, yes I am referring to the name of the device as mentioned in my 1st post:
so I cannot extract it from the event in anyway using analytics builder extract property object, correct?
The event contains only the id of the device but not the name. Depending on your model you may be able to use the Managed Object Input block to get the name. Make sure to enable “Capture Start Value”. If you are only interested in the name you can configure the “Property Name” parameter to be name. Be aware that changes to the name might trigger the model and if you are using groups make sure you implement the intended triggering behavior.
Thanks Harald for the valuable tip, I tested “Capture start value” and it is working perfectly as intended. I would like to double-check one thing:
why this feature should not be turned on if input source is “All inputs”? just because of the potential resources needed when we turn on the model? or something else? if it is just related to resources needed when turning up the model we can do it in non-peak time its fine
additional challenge: after taking the name in the previous step, now we need dynamically insert it as “input source” or an event. We used templates before but templates need to be done statically while our aim is to have this insertion dynamically on value fetch or value change, is it feasible?
