How to use create custom logs by using the output texts from Synapse notebook?

Question

Hi,

I am developing a Synapse notebook, and I want to use an output from Synapse notebook to create custom logs in Azure Log Analytics.

For example:

In a Synapse notebook, I define a string variable s = 'Cannot get the file status', and I want to output this text message into custom logs in Azure Log Analytics every time when I run this Synapse notebook.

How can I realize this?

Thanks,
Liang

Hello @Liang Chen ,

Thanks for the question and using MS Q&A platform.

You may try with below sample code for python logging with different format and customized log level.

 import logging  
      
 # Customize the logging format for all loggers  
 FORMAT = "%(asctime)s - %(name)s - %(levelname)s - %(message)s"  
 formatter = logging.Formatter(fmt=FORMAT)  
 for handler in logging.getLogger().handlers:  
     handler.setFormatter(formatter)  
      
 # Customize log level for all loggers  
 logging.getLogger().setLevel(logging.INFO)  
      
 # Customize the log level for a specific logger  
 customizedLogger = logging.getLogger('customized')  
 customizedLogger.setLevel(logging.WARNING)  
      
 # logger that use the default global log level  
 defaultLogger = logging.getLogger('default')  
      
 defaultLogger.debug("default debug message")  
 defaultLogger.info("default info message")  
 defaultLogger.warning("default warning message")  
 defaultLogger.error("default error message")  
 defaultLogger.critical("default critical message")  
      
 # logger that use the customized log level  
 customizedLogger.debug("customized debug message")  
 customizedLogger.info("customized info message")  
 customizedLogger.warning("customized warning message")  
 customizedLogger.error("customized error message")  
 customizedLogger.critical("customized critical message")  

Here is the expected output for the above sample code for python logging with different format and customized log level.

Hope this will help. Please let us know if any further queries.
