Hey @austinlogo , 

Yes, you definitely can. You just have to explicitly track that as an event in your product using one of our SDKs (catalog here). I would probably track it as an event, e.g. ‘Booking Error’ and then have one or more properties providing more context, e.g. ‘error_type’.

I hope this helps!

apologies, let me try and be a little clearer. I’ve seen amplitude visually distinguish errors in the timeline. (Red appearance, etc. ) I’m curious what triggers that as opposed to the typical green event styles.  I was hoping to be able to trigger that but for custom events not just ones that are picked up by thrown errors

@franciskafyi - apologies for the double post, but wanted to get the clarification on your radar.

Hi @austinlogo 

If by “timeline” you are referring to the user event stream, then afaik there are only 2 possible colors associated - Blue events are in-session events that are all connected by a line. Green ones are the out-of-session events which are stand alone. I haven’t come across any red colored entity yet.

Based on how you instrument your error events ( in-session vs out-of-session events ) , you will see their color accordingly.

Hope this helps.

@austinlogo did this help out? Fwiw, we get this color question often so I think a good support article will help out here to help decode what each color means.
