Parameters and Function of every control panel are described in a separate article of our Documentation (the articles are generated automatically). They contain all of the functions and parameters, which, however, may be not available in your installation. 

Use the mgrctl -i utility to get up-to-date information

To retrieve a full list of ISPmanager functions, you may execute the command

/usr/local/mgr5/sbin/mgrctl -m ispmgr -i 


To retrieve data description (the lang parameter can be used to get information in a required language)

/usr/local/mgr5/sbin/mgrctl -m ispmgr -i user lang=ru


In some of the most complicated cases, you can perform operations in your browser and view requests in the log file of the control panel

tail -f /usr/local/mgr5/var/ipmgr.log |grep "INFO Request"
