vdk-logging-ltsv 0.1.363986988

Versatile Data Kit SDK plugin that changes logging output to LTSV format.

This is a POC level implementation of a plugin which changes the logging format of vdk-core to LTSV for the purposes of structured data visualization.

The new format has the following fields, separated by tabs:

• timestamp: a timestamp of when the log is made;
• created: the same timestamp in the unix epoch format;
• jobname: the name of the data job;
• level: the logging level - one of INFO, WARNING, DEBUG, ERROR;
• modulename: the name of the module, inside of which the logging call is made;
• filename: the name of the file containing the logging call being made;
• lineno: the number of the line of code, at which the logging call is made;
• funcname: the name of the function, inside which the loggin call is made;
• attemptid: string identifying this particular execution of the data job;
• message: any additional logged information.

The label names follow the labelling recommendations found at http://ltsv.org/.

Usage

Switching vdk logging can be done by simply installing the plugin:

pip install vdk-logging-ltsv

And all logs will be automatically formatted to LTSV format. They would start to look something like this:
