Final answer:
In the context of software development log levels, the correct severity order, from least to greatest, is Debug, Info, Trace, Warning, Error, and Fatal. Each level represents escalating issues, where Debug is the least severe, used for detailed troubleshooting, while Fatal indicates a critical problem that could stop the application from running.
Step-by-step explanation:
The question asks about the correct order of severity for log levels. Log levels are used in software development for logging purposes, to track the behavior and errors of an application. The levels usually have a standard order of severity, from the least to the most severe, to help developers identify the criticality of an issue. The typical order is as follows:
- Debug: Provides detailed information, useful only for developers and troubleshooting.
- Info: Confirms that things are working as expected, for general informational purposes.
- Trace: Displays a higher level of detail than debug, it shows the steps leading up to a specific event or error.
- Warning: Indicates that there may be a problem, but the application can continue running.
- Error: Suggests that a function or request could not be completed successfully, but the application can still run.
- Fatal: Describes a severe problem after which the program might not continue running.
Therefore, the correct order of severity, starting from the least to the greatest, is Debug, Info, Trace, Warning, Error, and Fatal.
