An exception in AppDynamics is a code-level event that indicates a problem or abnormality in the

execution of a business transaction. AppDynamics captures and presents information on exceptions

in the monitored environment, and allows you to configure the rules and criteria for detecting and

reporting exceptions.

According to the Errors and Exceptions - AppDynamics, the following two types of events would be

marked as an exception in AppDynamics:

A custom-configured error method and error message: This is a type of event that you can define as

an exception based on a specific method and message that indicate an error condition in your

application code. You can configure the error detection rules to mark a business transaction as an

error and capture the exception information when such a method and message are encountered. For

example, you can configure a rule to mark a business transaction as an error and capture the

exception when the method com.example.MyClass.myMethod returns the message Invalid input.

Any message that is logged with a severity of Error or Fatal: This is a type of event that AppDynamics

automatically detects as an exception based on the log messages that are generated by your

application code. AppDynamics scans the log messages for the keywords Error or Fatal, and marks

the business transaction as an error and captures the exception information when such a message is

found. For example, AppDynamics will mark a business transaction as an error and capture the

exception when the log message contains Error: Null pointer exception.

Therefore, B (a custom-configured error method and error message) and C (any message that is

logged with a severity of Error or Fatal) are two types of events that would be marked as an

exception in AppDynamics. Reference:
