An error in AppMon can be any kind of unexpected event that happens while a user interacts with a system. Some examples of errors that can occur are resources that cannot be found on a web server, HTTP 500 response codes sent by a web service, or exceptions that occur within an application.

AppMon evaluates error detection rules on all PurePaths that arrive at the AppMon Server, and applies the defined consequences.

See Error Analysis for a full discussion of detecting and analyzing errors.
