One of our clients had a request where he wanted to track and filter changes on some entities per field level so he can filter them and check new and old values and react only if they had some value that was interested to him.
Now if we're talking about revisions then we track everything and client wanted to track only changes on some fields and not on whole entity in general. This led us thinking and we created a module for tracking changes on entities. The module is called Entity log and you can find it on this link below:
https://www.drupal.org/project/entity_log
When you install the module you can go to /admin/config/entity-log and setup which fields you want to track in log and select where you want to log changes (watchdog or Entity log entity).
It is simple enough for user (admin or moderator) to select fields he wants to track. (Check the image below)
After checking what you want you can create view that will be your log viewer. So lets do that below:
We select fields we want in our view like below and we have new entity log tracker.
Since this is a drupal entity you can create any kind of view that suits your needs for logging and with fields you want to be included. Hope you enjoy the module.
