When using hierarchical loggers, you only have to configure the logging objects where you want to change the filtering or propagation behavior Because messages naturally propagate to the root logger, it will ultimately be responsible for producing the output and any configuration that you made using basicConfig() will apply

Message Handling

Using Barcode creator for Visual Studio .NET Control to generate, create UCC-128 image in Visual Studio .NET applications.
Normally, messages are handled by the root logger However, any Logger object can have special handlers added to it that receive and process log messagesThis is done using these methods of a Logger instance log

Removes the Handler object handler from the logger The logging module has a variety of pre-built handlers for writing log messages to files, streams, system logs, and so forthThese are described in further detail in the next section However, the following example shows how loggers and handlers are hooked together using these methods

Using Barcode maker for ASP.NET Control to generate, create EAN13 image in ASP.NET applications.
When you add your own handlers to process messages, it is often your intent to override the behavior of the root loggerThis is why message propagation is disabled in the previous example (ie, the 'app' logger is simply going to handle all of the messages)

Handler Objects

The logging module provides a collection of pre-built handlers that can process log messages in various in waysThese handlers are added to Logger objects using their addHandler() method In addition, each handler can be configured with its own filtering and levels

Built-In Handlers
The following handler objects are built-in Some of these handlers are defined in a submodule logginghandlers, which must be imported specifically if necessary
handlersDatagramHandler(host,port)
Sends log messages to a UDP server located on the given host and port Log messages are encoded by taking the dictionary of the corresponding LogRecord object and encoding it using the pickle moduleThe transmitted network message consists of a 4byte network order (big-endian) length followed by the pickled record dataTo reconstruct the message, the receiver must strip the length header, read the entire message, unpickle the contents, and call loggingmakeLogRecord() Because UDP is unreliable, network errors may result in lost log messages
FileHandler(filename [, mode [, encoding [, delay]]])
Writes log messages to the file filename mode is the file mode to use when opening the file and defaults to 'a' encoding is the file encoding delay is a Boolean flag that, if set True, defers the opening of the log file until the first log message is issued By default, it is False
handlersHTTPHandler(host, url [, method])
Uploads log messages to an HTTP server using HTTP GET or POST methods host specifies the host machine, url is the URL to use, and method is either 'GET' (the default) or 'POST'The log message is encoded by taking the dictionary of the corresponding LogRecord object and encoding it as a set of URL query-string variables using the urlliburlencode() function
handlersMemoryHandler(capacity [, flushLevel [, target]])
This handler is used to collect log messages in memory and to flush them to another handler, target, periodically capacity is the size of the memory buffer in bytes flushLevel is a numeric logging level that forces a memory flush should a logging message of that level or higher appearThe default value is ERROR target is another Handler object that receives the messages If target is omitted, you will need to set a target using the setTarget() method of the resulting handler object in order for this handler to do anything
handlersNTEventLogHandler(appname [, dllname [, logtype]])
Sends messages to the event log on Windows NT,Windows 2000, or Windows XP appname is the name of the application name to use in the event log dllname is a full path name to a DLL or EXE file that provides message definitions to hold in the log If omitted, dllname is set to 'win32servicepyd' logtype is either 'Application', 'System', or 'Security'The default value is 'Application'This handler is only available if Win32 extensions for Python have been installed
