StderrBackend

StderrBackend wrapper

class DIRAC.Resources.LogBackends.StderrBackend.StderrBackend(backendParams=None)

Bases: AbstractBackend

StderrBackend is used to create an abstraction of the handler and the formatter concepts from logging. Here, we gather a StreamHandler object and a BaseFormatter.

  • StreamHandler is from the standard logging library: it is used to write log messages in a desired stream so it needs a name: here it is stderr.

  • ColorBaseFormatter is a custom Formatter object, created for DIRAC in order to get the appropriate display with color. You can find it in FrameworkSystem/private/standardLogging/Formatter

__init__(backendParams=None)

Initialization of the backend. _handler and _formatter can be custom objects. If it is the case, you can find them in FrameworkSystem/private/standardLogging/Formatter or Handler.

Parameters

  • _handler – handler object from ‘logging’. Ex: StreamHandler(), FileHandler()…

  • _formatter – the name of a formatter object from logging. Ex: BaseFormatter

  • backendParams (dict) – parameters to set up the backend

  • _datefmt (str) – parameters to set up the formatter (e.g. fmt, the format, and datefmt, the date format)

  • _level (str) – level of the handler

getHandler()
