To make the logging of events consistent, PyOptiSLang has a specific logging architecture with global and local logging instances.

For these two types of loggers, this is the default log message format:

>>> from ansys.optislang.core import Optislang
>>> osl = Optislang(loglevel="INFO")
>>> osl.log.info("This is an useful message")
    NEW SESSION - 08/26/2022, 10:02:25

INFO -  osl_process - optiSLang_2827215940360 -  __init__ - optiSLang executable has been found for version 222 on path: C:\Program Files\ANSYS Inc\v222\optiSLang\optislang.com
INFO -  tcp_osl_server - optiSLang_2827215940360 -  __listen_port - optiSLang server port has been received: 5310
INFO -  tcp_osl_server - optiSLang_2827215940360 -  connect - Connection has been established to host and port 5310.
INFO -  tmp1 - optiSLang_2827215940360 -  <module> - This is an useful message

Because both types of loggers are based in the Python logging module, you can use any of the tools provided in this module to extend or modify these loggers.

Logging API#

These classes are specific to the ansys.optislang.core.logging module:

OslLogger([loglevel, log_to_file, ...])

Provides the logger class created for each session.
