sys.stdout.write = logger.info sys.stderr.write = logger.error What this does is simply assign the logger functions to the stdout/stderr.writecall which means any write call will instead invoke the logger functions. The downside of this approach is that both calls to.writeand the logger ...

Use the USEROUTPUTCLASS option in a JVM profile to name a Java class that intercepts the stdout stream and stderr stream from the JVM. You can update this class to specify your choice of time stamps and record headers, and to redirect the output.
When we pipe output from one process into another we sort of connect stdout of the first one to stdin of the second. So, to be able to see my giant stack trace, we can for example redirect stderr to stdout. This way we will get both streams into stdin of the next process....
Of course, we would need to capture both stdout and stderr in a production application.Redirect Logs to a File In or Out of The Container?We covered several different ways to redirect docker logs to a file for saving and analysis. The best method is the one that works for you....
