How can I change the location of the sphera logs?
In order to change the path of the log file of any component of the Hosting Director you should change the parameter in the xml of the component itself, under the parameter log_file.
In addition you will need to change the file syslog.conf under the/etc/ directory of the machine.
Each component installation adds it's own log path to that file.
As usual the change of any XML file should be done only after stopping the component and backing up the XML file.
