python logging debug

logs are also exported to three destinations defined by handler. If you call Logging.getloggeer (' Simpleexample '), the logger instance that matches the name ' Simpleexample ' in the configuration file is created, and its handler is console, which is the output log on the console.Logging.handlers.RotatingFileHandler can implement automatic log file coverage, if you need to implement log file changes (such as deleted) automatically generated, you need to use Logging.handlers.WatchedFileHandler,

That is, overwrite the previously saved log informationV.

First introduce how to find out, the line of the project log is through the logging module to the Syslog, ran for a period of time to find the syslog UDP connection over 8W, yes 8 W. The main logging module is wrong. One of the requirements we had before is to output the current connection information for each connection log, so each connection creates a log instance, assigns a Formatter, and creates a log

I have several projects that use Sentry to capture the ERROR level of the log and now have a problem: when debugging locally, all handler (including root) in the log settings are only hit on the console, but exceptions that are not caught in local debugging will hit the line sentry Above, and the caught exception follows my log settings and only hits the console. I wonder if the uncaught exception is not the root handler of the walk?My solution is to read through the
