Logging

Austin uses syslog on Linux and macOS, and %TEMP%\austin.log on Windows for log messages, so make sure to watch these to get execution details and statistics. Bad frames are output together with the other frames. The error rate depends on the workload: it is generally low, but it can be higher for applications whose stacks change very rapidly, e.g. with many short calls or deep recursion.

Logging can be disabled using environment variables.
