How often do items get out of stock?

[filipefurtad0]

What is the question we want to answer?

We want to know how often do users experience an item finishing stock, before the order actually is completed.

What type of data do we need to answer this question (and how to get it, if known)?

One approach could be measure how often do users see the out of stock banner.

Potential solutions that will solve the problem? [[brainstorming on how to access the data, using Matomo, Metabase, other]

Proposed solution: Set up an event on Matomo, to observe when the out of stock banner is triggered.

How does an order look like, when an item is of stock, in the DB? Maybe there are some features which allow setting up queries on Metabase?

The element in event we wish to track has class=alert-box:

with text:
An item in your cart has become unavailable. Please update the selected quantities.

On URL:
/cart

Ok, I've found this configuration to work in staging:

1. A goal

2. A view trigger:
   

3. A tag pointing to the Goal created step 1) and the trigger set up in step 2)

This can then be seen on the Goals results:

Ok, this is now working for UK-prod:

The cool thing about it, is we can see which shop is triggering this the most:
