This logger package provides a few helper classes to minimize the performance impact of writing logs. If you desire additional options, please open an issues.
composer require bjoern-buettner/loggerAll mentioned classes can be found in the namespace Me\BjoernBuettner\Logger.
The eager monolog round robin file handler for Monolog writes directly to a set of files, that are randomly chosen from a list of possible files. This means, that the chance of a file being written to by multiple handlers at once gets way smaller, removing nearly all of the performance impact.
This is a psr-compatible implementation of a logger only dumping the messages from memory after a request finished. This completely removes the file access overhead from the user-measurable webrequest speed.
The lazy monolog handler facade is an implementation of a Monolog handler only dumping the messages from memory after a request finished. This completely removes all remote access overhead from the user-measurable webrequest speed.
