Exception Stack Trace Lines

This parameter will appear only if the advanced settings flag is set to ‘true’. As part of detailed diagnostics, this test, by default,  lists the first 10 stacktrace lines of each JavaScript error/exception that it captures on the target JVM node for a specific transaction, so as to enable easy and efficient troubleshooting. This is why, the exception stacktrace lines parameter is set to 10 by default. If required, you can have this test display more or fewer stacktrace lines by overriding this default setting.
