aib_custom_logger

This serves as the official documentation for the PyPi package developed by the AIB MLOPS team called "aib-custom-logger".

Introduction

The "aib-custom-logger" pypi pkg offers the abilty to throw logs that contains meaningful metadata, which can be used in both debugging and monitoring.

Usage

The pkg exists in the aib-mirror, once you install the pkg using "pip install aib-custom-logger", you can proceed to use it as follows:

 from aib_custom_logger_tst.aib_custom_logger import aib_logger
 
 my_logger=aib_logger(project_id,pipeline_name="{{$.pipeline_job_name}}")
 
 my_logger.log(
  f"Batch prediction job output info: {job.output_info}",
  category=aib_logger.Categories.DATA,
  action=aib_logger.Actions.CREATE,
  extra_labels=['batch_prediction','automl']
 )

1.init()

After you import the pkg you need to initialise an object of the aib_logger class. The constructor takes the following params:

• project (str): Required. The project id of to add to the google cloud client for logging.
• pipeline_name (str): Optional. The pipeline run name that this log was thrown from. This can be achieved by passing the placeholder "{{$.pipeline_job_name}}" which will be replaced by the run_name at run time. Default is empty string "".
• logger_name (str): Optional. The name of the custom logger which you can then query by. Default is "aib_custom_logger".

2.Log()

the log function takes the following params:

• msg (str): Required. The content you wish to log.
• category (aib_logger.Categories): Optional. An enum to choose from relating the category of the log. Default is "Other".
• action (aib_logger.Actions): Optional. An enum to choose from relating the action of the log. Default is "Other".
• severity (aib_logger.Severities): Optional. An enum to choose from relating the level of severity of the log. Default is "Info".
• extra_labels (list): Optional. Extra custom labels to add to the log.
• object (dict): Optional. An extra custom dictionary to be added.

3.Categories

The following are the available categories (key=value) defined in the aib_logger.Categories enum:

MODEL = "Model"
DATA = "Data"
METRIC = "Metric"
OTHER = "Other"

4.Actions

5.Severities

The following are the available severities (key=value) defined in the aib_logger.Severities enum:

INFO="INFO"
WARNING="WARNING"

Querying

In order to see the logs being produced by your pipeline, you need to navigate to the logging page in GCP and start querying.

logname: you can query for all the logs that were produced by a specific custom logger name.

jsonpayload: the jsonpayload holds the content of your logs and the metadata. It is a key value object as seen below.

Limitations

Currently the custom logs yielded by this pkg can only appear in the logging page, and not the logs section in the vertex pipelines UI.
