Hi,
I am looking at subscriptions vs polling to detect changes in Tables on other elements in the same DMS. I would like to be notified of changes to a single column/Parameter id in a table.
Is there a guide or example showing how to create a subscription and if necessary filter to detect a single column?
Thank you.
Jon.
Hi,
If you're using DIS then the class library could be used for this. See subscription monitors help section. As far as I'm aware, this can only be used to subscribe to a table cell so there is a separate subscription needed per primary key. Subscribing to a column in one go with this method is probably not possible at this moment with the class library.
Hi Jon,
One way to achieve this is by creating a table in the protocol in which you want to retrieve the updated values. That table must contain a column that mimics the table column to which it is linked and has the same number of rows. The data is linked by making use of virtual attribute in the protocol and element connections on DataMiner level.
