Database Logs
In your database Logs tab, GrapheneDB shows the logs natively provided for monitoring purposes. You'll be able to select the log that you want to retrieve and filter it by Errors or Warnings, but also to choose to show All logs.
We've brought to you a great feature to help you with debugging and have quicker insights into what you're looking for, and it's called Log Analyzer.
If the database is in a Paused state, logs are not visible. You will need to Resume your database to see the log entries.

Log Analyzer
The Log Analyzer is a feature designed to help you reduce the time used in locating the most important information. Log Analyzer goes through the log that is loaded and extracts extracts relevant information to map it to an explanation. First of all, it filters warnings, errors, and some interesting info that you can easily switch between.
Additionally, for some logs, we offer an extended explanation related to errors, warnings or info in the log. For example, you'll be able to see detailed explanations in an event of the database being stopped.
If you click on Navigate button, it will bring you to the exact line in the logs that this extended explanation refers to, being an error, warning, or info, depending on what you've selected.
