Installation

pip install lognostic

Development

• Clone this repository
• Requirements:
  • Poetry
  • Python 3.9+
• Create a virtual environment and install the dependencies

poetry install

• Activate the virtual environment

poetry shell

Custom logging Handler

The lognostic module can be integrated into logging subsystems by employing a custom logging handler:

class LogHandler(logging.Handler):
    def __init__(self, lognostic: Lognostic):
        super().__init__()
        self._lognostic = lognostic

    def emit(self, log_record: logging.LogRecord):
        self._lognostic.record(log_record)

A Lognostic instance should be given to the custom logging handler, so later logging statistics can be obtained:

lognostic = Lognostic()
loghandler = LogHandler(lognostic)
logger.addHandler(loghandler)

logger.info('This is a test log message')

lognostic.total_size() # -> returns 26

Documentation

The documentation is automatically generated from the content of the docs directory and from the docstrings found in the source code.

Testing

Run unit tests using

pytest tests

Automated test runs: The lognostic package is automatically tested through python versions 3.9 to 3.12 using GitHub's CI/CD pipeline.

Docker Usage

Build the image of the Dockerfile using

docker build -t lognostic .

Run the image with

docker run --name lognostic_instance lognostic

The docker builds the envioronment followed by running the pre-commits and unit tests.

Pre-commit

Pre-commit hooks run all the auto-formatters (e.g. black, isort), linters (e.g. mypy, flake8), and other quality checks to make sure the changeset is in good shape before a commit/push happens.

You can install the hooks with (runs for each commit):

pre-commit install

Or if you want them to run only for each push:

pre-commit install -t pre-push

Or if you want e.g. want to run all checks manually for all files:

pre-commit run --all-files

Future features and improvements

• Data persistency: Store statistics on the disk persistency for future historical logging analysis.
• Logging Dashboard: A web dashboard to visualize logging statistics in real-time, allowing teams to monitor logging load dynamically.
• Throw warning/error messages if certain logging thresholds are met, such as an unusually high logging rate, to quickly identify potential issues.
