Product definition
Scoped the one-day build around a clear operational task: turn a log file or standard-input stream into a useful first-pass incident summary.
Open Source / Python Automation / Daily Build
Log Signal
/ Overview
A dependency-free Python CLI that turns noisy plain-text logs into a compact severity and recurring-signal report.
Large plain-text logs repeat the same underlying problem with changing IDs, addresses and counters, making the important patterns difficult to spot quickly.
/ Provided servicesClear thinking.
Clear thinking.
Practical delivery.
Signal design
Defined readable severity totals, unmatched-line counts and recurring signatures without storing or uploading log content.
Python engineering
Implemented parsing, normalization, aggregation, reporting, file handling and meaningful exit codes using only the Python standard library.
/ Solution
I built a standard-library Python CLI that recognizes common severity labels, normalizes volatile identifiers, ranks recurring message signatures, counts unmatched lines and can emit text or JSON reports.
/ Impact
Severity totals at a glance
Recurring messages grouped by signature
Text and JSON output
Ten passing standard-library tests
Python
Dataclasses, type hints, regular expressions and Counter-based aggregation power the parser and report model.
CLI & JSON
Argparse supports files or stdin, top-signal limits, human-readable output, machine-readable JSON and opt-in exit-code behavior.
Unittest
Ten tests cover level parsing, normalization, unmatched lines, ranking, report limits, JSON output and error exit codes.
