Hi @Vaibhav Vir.Singh, The problem I have turns out to be that appd BT's aren't designed to report errors on asynchronously called downstream tiers. "Errors that occur on a downstream tier that are not propagated to the originating tier do not result in a business transaction error. If the originating client receives a 200 success response, for example, the business transaction is not considered an error. The error contained within the downstream tier does count against the Error Per Minute metric for the continuing segment. " https://docs.appdynamics.com/22.6/en/application-monitoring/troubleshooting-applications/errors-and-exceptions It's pretty frustrating honestly as I can't do accurate alerting on the BT, but I have raised an IDEA to fix it.
