I'm trying to understand when it's best to use JSON versus plain text for logging. I'd like a straightforward explanation of the pros and cons of each format. Can someone shed some light on this?

Use plain text when you just have simple messages. If you’re dealing with complex objects or need detailed context, then logging in JSON makes sense! Otherwise, keep it simple!
JSON is great if you need to attach metadata like UserId, RequestId, or TraceId to your log messages. It helps avoid issues that come with special characters like new line breaks in plain text.
But keep in mind, JSON can bloat your logs. You might be logging the same info redundantly, which can be wasteful. Often, a structured plain text format with clear indicators is all you need for basic logging.
If you're troubleshooting in production, structured logging with JSON can be really helpful. It allows for easier filtering, making it simpler to spot issues when it counts. However, it can also come across as overly complex; sometimes simpler plain text logging is more straightforward.
Honestly, it really depends on the context. Each situation is unique, and the decision should be based on what you're logging and your specific needs. Good logging practices evolve with the codebase and application history; there's no one-size-fits-all answer!
Exactly! It’s all about balancing complexity and clarity in your logs.
