title: Set Python Logging to Azure Blob, but Can not Find Log File there
body: <p>I'm setting up logging on a flask service. I  tried to write logs to an azure blob storage with the following code</p>
  
  <pre><code>import logging
  import sys
  
  from azure_storage_logging.handlers import BlobStorageRotatingFileHandler
  
  logger = logging.getLogger('service_logger')
  logger.setLevel(logging.DEBUG)
  log_formater = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(process)d - %(message)s')
  azure_blob_handler = BlobStorageRotatingFileHandler(filename = 'service.log', 
                                                      account_name='servicestorage',
                                                      account_key='',
                                                      maxBytes= maxBytes,
                                                      container='service-log')
  azure_blob_handler.setLevel(logging.INFO)
  azure_blob_handler.setFormatter(log_formater)
  logger.addHandler(azure_blob_handler)
  </code></pre>
  
  <p>Then, I tried with logger.warning('test warning'), but there's not log file created on the azure blob container. </p>
  
  <p>Can anyone help me figure out where I did wrong?</p>
  
  <p>Best,
  Eigen</p>
