I'm using the BrightCove Video Tracking extension and have a couple of the data layer objects from the utag.link call mapped to the Adob appmeasurement tag, but nothing is working. I do not see link calls happening and I see no variables populating. Since the info in the above referenced article is a bit dated, I was wondering if there was any update. ... View more

Hi @shwetabakshi, Some time ago, while working in an agency, I worked on migrating a rather large GTM setup to Tealium iQ. To start with, we moved their GTM container tag into Tealium iQ, so that we also controlled when it was removed from the site, of course after the migration was done. It did of course come with lower performance of the GTM setup, but I was actually surprised to see how little, since I myself anticipated a lot worse performance than we got, even though it was a rather big setup, we ran from that GTM container. So, if we're talking about putting GTM in Tealium iQ, or running the two in parallel, I wouldn't be worried much about doing it. If we then talked about running Ensighten Manage and Tealium iQ together, well, then I would have to get back to you. Haven't tried that out yet, but I would have to try that sometime in the future ;-) I totally agree with @UnknownJ, that you should be prepared for somewhat worse performance, either in both, or one of implemented TMS', of course depending on how you were to do the implementation. Best regards, Peter ... View more

For unbundled tags, load is based on evaluating the relevant load rule, whereas send defaults to 1. So if a given tag's load rule condition isn't met, @johannaalvarez, it's through the load flag that it's suppressed, rather than the send flag (which will never be tested if the tag hasn't been loaded). ...

Hi @shwetabakshi u.extend works in the same way that utag.handler.extend does, except without the need for a matching configuration object because the only extensions that are stored in there are the tag-scoped extensions for the tag in question (the contents of u.extend are generally found in a specific utag.x.js file, as opposed to the main utag.js (unless your tags are bundled)) When an event is sent to a tag, prior to undertaking the mapping process, the tag template will iterate over u.extend and run the functions within against the tag's local copy of the event payload prior to data being mapped. An example from the Tealium Learning Community would be utag.sender[21].extend[2], which runs: function(a,b){ try{ if(b['tealium_event']=='item_pressed'){ b['ga_event_category']='Custom_Click'; b['ga_event_action']=b['item_area']; b['ga_event_label']=b['item_name'] } }catch(e){ utag.DB(e) } } And maps a couple of generic variables to specific Google Analytics variables, ready to then be mapped into the tag. Then utag.loader.EV is a function that usually adds an event listener to an object, thus: utag.loader.EV = function(target_object, event_type, handler_function){ ... } However, if event_type above is "ready", then it sets the handler function to run at DOM Ready, which is either almost immediately (sets a timeout for 1ms) if the page has already loaded, or otherwise the functon is passed into a queue (the array utag.loader.ready_q) and an event listener set against the DOMContentLoaded event against the document to run through it (the function utag.loader.run_ready_q). This is how DOM Ready scoped extensions are executed, so you should see a utag.loader.EV call for each DOM Ready extension that you've got. There are some features of Tealium that also run at DOMContentLoaded, so there will be elements in the queue that weren't derived from extensions as well. ... View more
