Several issues here

1. An issue enunciates a problem, does not propose a solution. Choosing a log tool over another should be part of a decision process that examines the state of the art against project requirements.
2. There can be no issues without user stories. This issue does not refer to any user story.

Additionally, it's extremely important that you develop the project in different stages, introducing logging (or, for that matter, any other feature) only when the MVP requires you to do so. It's extremely early to do this kind of thing.

Please don't state decisions in the issues, like selecting one log over others. This has to be the response to pre-established criteria, which is what you have to lay out in the issue.
