License logs

Logging can be enabled for the Four Js License Manager (FLM) and/or the license controller.

Requests and responses that are sent and received by the license controller or Four Js License Manager (FLM) may be recorded in log files. These logs are intended for the troubleshooting of licensing issues by decoding and reviewing events. You may be asked to activate logging in order to assist Four Js support with a licensing problem.
Note: The logs are encoded and are not intended to be readable by users.
Activating this logging feature is dependent on how your license management is implemented.

Local license controller logs

If you are using a license controller (fglWrt, greWrt, or grxWrt) for license management, the log feature is configured in the FGLPROFILE file or by setting environment variables.

fglprofile configuration

To affect all license controllers, enable logging in the FGLPROFILE file.

Logs can be enabled using these entries:
  • flm.log.enabled=1
  • flm.log.directory="/tmp"
Environment variables
You can control which license controller processes inherit environment variables. For example, you can use a production installation for a single test and avoid changing the context where production executes.
Tip: Sometimes this method is easier than updating a configuration file.
Logs can be enabled using these environment variables:
  • WRT_LOG_ENABLED=1
  • WRT_LOG_DIRECTORY=/tmp
A wrt-<timestamp>.log file is created in the specified log directory. A new log file is created each day. If logs are enabled and no directory provided, the output goes to stderr.
Tip: License controller logs can also be enabled locally when using an FLM.

Four Js License Manager (FLM) Log

If you are using FLM, a log feature is available (FLM version 5.10.3u or later). The log can be enabled by setting the entry flm.cnxlog.enabled=1 in $FLMDIR/etc/lmprofile.

After making a configuration change, you will need to restart the FLM. After the restart, you get an flm.log file in the $FLMDIR directory.
