Debug Log Level Values

Debug Log Level Values


These are the values you can set for the debug level under:

Site administration > Development > Debugging

For Debug message (debug). You can also query this from the mdl_config table looking at the key debug.

  • 0 = NONE: Do not show any errors or warnings
  • 5 = MINIMAL: Show only fatal errors
  • 15 = NORMAL: Show errors, warnings and notices
  • 30719 = ALL: Show all reasonable PHP debug messages
  • 32767 = DEVELOPER: extra Moodle debug messages for developers

Those are values you can set in the database for the debug entry in mdl_config if you need to check or change this on the database. You need to purge your cache as well.

NOTE: even on production sites, leave the setting at MINIMAL instead of NONE to help with troubleshooting as some errors are very time/user specific and hard to replicate. If your PHP error is filling up on this setting, it indicates an underlying issue.

These are defined with PHP error constants in lib/setuplib.php as follows:

  • DEBUG_NONE = 0
  • DEBUG_MINIMAL = E_ERROR | E_PARSE
  • DEBUG_NORMAL = E_ERROR | E_PARSE | E_WARNING | E_NOTICE
  • DEBUG_ALL = E_ALL & ~E_STRICT
  • DEBUG_DEVELOPER = E_ALL | E_STRICT
These constants may vary depending on Moodle versions.
