Logging#

The toolkit generates logging messages, that can warn and help the users. By default, only Warnings are logged to the console. If you want to read the logs, you can do this by:

  • forwarding the logs to a file –> this file will be updated with log messages (live). Use the metobs_toolkit.add_FileHandler() method.

  • Print logs in your console (i.g. your coding environment) –> this will print out the logs in your coding environment (live). Use the metobs_toolkit.add_StreamHandler() method.

Stream Logs#

To stream logs, call the add_StreamHandler() function.

[1]:

import metobs_toolkit

# Forward the logs to the coding environment
metobs_toolkit.add_StreamHandler(setlvl='INFO')

#Import a dataset to generate logs
dataset = metobs_toolkit.Dataset()
dataset.import_data_from_file(
        input_data_file=metobs_toolkit.demo_datafile,
        input_metadata_file=metobs_toolkit.demo_metadatafile,
        template_file=metobs_toolkit.demo_template,
        )

File logs#

To write logs to a file, call the add_FileHandler() function, and specify the path.

[2]:

from pathlib import Path

target_logfile = Path.cwd() / 'example_logfile.log'
metobs_toolkit.add_FileHandler(filepath=target_logfile, #path to the logfile (can be nonexisting)
                               setlvl = 'INFO',
                               clearlog=True)

#Import a dataset to generate logs
dataset = metobs_toolkit.Dataset()
dataset.import_data_from_file(
        input_data_file=metobs_toolkit.demo_datafile,
        input_metadata_file=metobs_toolkit.demo_metadatafile,
        template_file=metobs_toolkit.demo_template,
        )
