About

Simple custom database logger.

Use cases

• Dev/Debug and monitoring purposes as alternative to wasteful CLI output and the default file based logging.
• Reduce flood of information generated e.g. by impending API calls, jobs and general service access, and filter the relevant ones. For instance, if there's a bug you might not need to see the same message a hundred times.

Concepts

• Log messages can go into certain channels, like with the CLI loggers (define your own)
• Log messages are hashed and hashsums stored, so that duplicates can later be found/ filtered

Setup

Requirements

• Symfony 3.4 or higher
• Doctrine ORM

Use

1. Implement in your Symfony application
2. Update Doctrine schema
3. Test via command ./bin/console test:systemlogs

Todo

• Check if hashsum algorithm is safe to use
• Consider implementing an additional, suggested data normalization tool
  • e.g. to scrub/ sanitize/ anonymize log or API data
