Hi there,
Another way to validate if event x is being sent to audience manager or not is using browser developer tools.
1.Open the page in your website where "eventx" is fired and filter the network calls in browser developer tools using b/ss.
2.b/ss is the filter for adobe analytics call.
3.Open the analytics call and check for events:"eventx" value in query string parameters.
4.If the value is present that means eventx is being passed to audience manager.
Something like below:
