These cause writes to the various debug logs; another one to look out
for is wfDebugLogFile, which directs debugging output to a specific
log group.

See $wgDebugLogFile and $wgDebugLogGroups (both commented in
includes/DefaultSettings.php) for further details.

Set $wgDebugLogFile to point to a (writable) file; debug messages will
be sent there.

Note that you can also assign messages to individual log files by using
wfDebugLog() instead of wfDebug() and setting up separate files for the
groups you're interested in in $wgDebugLogGroups
