Starting from Plesk 11.5, you can configure logging in the [log]
section of the
panel.ini
file.
To enable or disable logging of SQL queries performed on the Plesk
database, use the log.show.sql_query parameter, for example:
log.show.sql_query=true
To enable or disable the support for multithreaded logging, use the
log.show.thread parameter, for example:
log.show.thread=true
See more parameters in the
panel.ini.sample
file.
