Command Logging
This feature logs controller commands from both CLI and 3DM2 into a file. You may be asked to supply this logfile to tech support for troubleshooting.
Set the environment variable TW_CLI_LOG to ON or OFF to enable or disable logging of controller commands into a log file called tw_mgmt.log.
By default, TW_CLI_LOG is set to OFF. The command to start command logging varies by operating system.
•For FreeBSD, Redhat and SuSE, (bash, ksh, or sh), enter
export TW_CLI_LOG=ON
•For Linux (chs
setenv TW_CLI_LOG ON
•For Windows, enter
set TW_CLI_LOG=O
In Linux, and FreeBSD, the log file is in /var/log directory.
In Windows, the log file is in the 3DM2 installation directory if 3DM2 is installed in the system. Otherwise, it is in the current user home directory.
