An async TCP logging server base on tornado.ioloop, which serve for logging.handlers.SocketHandler.
To solve Python separate processes logging to same file.
Official description:
Although logging is thread-safe, and logging to a single file from multiple threads in a single process is supported,
logging to a single file from multiple processes is not supported, because there is no standard way to serialize access
to a single file across multiple processes in Python. If you need to log to a single file from multiple processes, one
way of doing this is to have all the processes log to a SocketHandler, and have a separate process which implements a
socket server which reads from the socket and logs to file.Reference: logging cookbook
LoggerServer use tornado build a high-performance TCP logging server to slove this problem.
Install LoggerServer by pip
pip install logger_server
