How do I enable/disable debug logging in * Plesk 11.5 * and up under Linux?
Resolution
First you should copy sample config
/usr/local/psa/admin/conf/panel.ini.sample
to/usr/local/psa/admin/conf/panel.ini
, unlesspanel.ini
already exists there:# ll /usr/local/psa/admin/conf/ | grep panel -rw-r--r-- 1 root root 317 Feb 6 11:39 panel.ini -rw-r--r-- 1 root root 198 Oct 15 16:01 panel.ini.original -rw-r--r-- 1 root root 1542 Dec 10 17:06 panel.ini.sample
To enable debug logging, you should uncomment (remove
;
semicolon at the start of the string) following lines inpanel.ini
:[debug] ; Enable debug mode (do not use in production environment) enabled = on [log] ; Log messages verbosity level (from 0 to 7) ; 0 - only critical errors, 7 - all including debug messages, default - 3 filter.priority = 7 ; Enable logging of SQL queries show.sql_query = on ; Enable logging of external utilities calls show.util_exec = on
To disable debug logging you should comment the above lines in
panel.ini
.- Log with enabled debug mode can be found in
/usr/local/psa/admin/logs/panel.log
file.
This works for pretty much any Plesk executable, including small binaries.
Example:
# /usr/local/psa/bin/ip_ban --update -ban_period 600 -ban_time_window 600 -max_retries 10
DEBUG [dbquery] [0] SQL: SET sql_mode = ''
DEBUG [dbquery] [0] END: 0.00023102760314941 sec
DEBUG [dbquery] [1] SQL: SET NAMES utf8
DEBUG [dbquery] [1] END: 0.00013208389282227 sec
DEBUG [dbquery] [2] SQL: connect
DEBUG [dbquery] [2] END: 0.00038313865661621 sec
DEBUG [dbquery] [3] SQL: SET sql_mode = ''
DEBUG [dbquery] [3] END: 0.00014400482177734 sec
...
SUCCESS: The settings were updated.
To suppress DEBUG messages from this binary, we comment out (add ;
semicolon at the start of the string) filter.priority = 7
in panel.ini
.
Output will then look like this:
# /usr/local/psa/bin/ip_ban --update -ban_period 600 -ban_time_window 600 -max_retries 10
SUCCESS: The settings were updated.
Changes take effect immediately (e.g. there is no need for service psa restart
or other such commands), because small binaries like ip_ban
read those settings each time they are started.
There are also other options which will allow you to hide some of the log messages. Among them are:
; Enable logging of SQL queries
show.sql_query = on
; Enable logging of external utilities calls
show.util_exec = on
; Enable logging of stdin and stdout for external utilities calls (do not use in production environment)
show.util_exec_io = on
