How to view and analyze Custom errors

Custom errors enable you to track any line of code being executed, while users navigate your website. For example, if there's a line of code being executed when users try to purchase an item that’s out of stock, even though your site might have logic that prevents them from getting to the purchase page (for out of stock items).

How to segment by custom errors

There are two key ways to segment by custom errors:

• From the Segments capability: From the main menu, go to ‘Analysis set-up' tab > 'Segments’ to create and save a new segment to be used across other modules.
• From the analysis context: From the menu go to ‘Error Analysis’ and click the ‘All users’ button from the analysis context.
  

Here's an example of segmenting by custom errors directly from the analysis context:

1. From the segment dropdown, search and select for the user action ‘Errors’.
2. Select ‘users who visited’: ‘any page’ or a ‘specific page’.
3. Select whether they ‘experienced’ or ‘haven’t experienced’ the error.
4. Select whether they experienced:
   1. ‘Any custom error’.
   2. ‘A custom error’: either enter the text of the custom error in the ‘that contains’ field, or the value of the attribute into ‘has a custom attribute’ field (or you can enter both).
   3. ‘An exact custom error’: enter the ‘error name’ and optionally add the value of the ‘custom attributes’.
   4. ‘A grouped custom error’: enter the ‘group ID’.

5. Click ‘Apply’. Or, click ‘Save as new Segment’ for future analyses.
