The main benefit of using distributed logging for microservices observability is increased visibility and insights. 

By collecting and storing log data from each individual microservice in a central repository, you can gain a complete view of what is happening in your system. 

This allows you to track and diagnose issues, identify potential problems, and take corrective action.

 Other benefits of distributed logging include improved performance, scalability, and better reliability and availability.
