The record module is used to command active runtime nodes to start and stop recording data to the hard drive. It uses the UTC timestamp─of the moment record is pressed─to name and identify the logfile session. In a single host system, all data is recorded and written to the same location. Runtime nodes record data on the local host they are executing on in a distributed system. Each host has a unified `rnr_logs` directory where data is written to. This is defined in the SDF Configurator in the "RnR Logs" directory. To replay the recorded data on another system, check out this [Exporting Recorded Data](/articles/?p=862) article.
