How to write logs

The logging system uses the classical Python logging library so all the features that are available in the library are mostly available. For certain features, you might need to set the value of the loglevel or the formatter value of the config as described in How to configure HTTP.

If you need to use advanced features of logging, you can check the Python Logging Library, which should contain the informations you need.

When logging using one of the standard logging functions such as debug, info, warn, warning, error and critical, you can pass extra arguments that will be displayed in the final dashboard if correctly configured. For example, you can do the following :

logging.critical( "Some critical message", extra = { "arg": 42 } )
