Script Editor Logging Level

Choose the amount of verbosity you desire to be output into the Maya Script Editor. Debug has the most output, useful for problem solving, with Info being the least and displaying progress information.

Disk Logging Level

Output logs written to disk and have the same options as Script Editor above but include Error, Critical, and Warning message levels.
