This node logs the raw data from the node input into the file and propagates the data from the input to the output terminal.

Flow variable substitution is supported in the log file name. In order to generate unique log file name use the Flow internal variables _FLOWINSTANCE_ or _FLOWUUID_.

Flow variable FLOWLOGNODES changes the Log node behavior.

If the variable is set to false, the log file name will not be created. If the variable is set to true, the unique log will be created. The unique log fine name is [Nodename]_%_FLOWUUID_%.log.
