How to Set Up Web Tag Monitoring for Developer Console

Learn how to configure your web tags to log error notices in your developer console.


Web Tag Monitoring can log an error in your Developer Console when an error linked to GTM is triggered on your site. This uses Google Tag Manager's native Debug Mode Variable, which will only log errors when not in Google Tag Manager's Preview Mode.

If you're using Elevar's pre-built web tags, you simply need to turn on the monitoring following these steps.

How To Turn On Web Tag Monitoring

Elevar's pre-built web tags are already wrapped in the error monitoring setup, but the monitoring is turned off by default. To turn on the monitoring, follow the below steps:

Step 1: Log Into Google Tag Manager

Google Tag Manager

Step 2: Navigate to the Elevar Monitoring Core Tag Tag

Navigate to Tags > Find and select the Elevar Monitoring Core Tag.

Step 3: Set Debug Mode Variable to true

Under Debug Mode Variable, set the input to "true". Note: you could also set the value to "1".

Be sure to save your changes!

Step 4: Publish Changes

Press Submit > then Publish!

Now, when you navigate your website, if an Elevar tag has an error, this will be logged in your Developer Console like the below.
