The Playback view records in-flowing data to a playback file, and plays the captured data back into a running Event Stream Processor instance. You can also use it in place of the File Upload tool to upload data files at a controlled rate. All date and time stamps within the Playback view are assumed to be in UTC.

Full rate | Full rate indicates that the speed of playback is not imposed by ESP Studio. Full rate is dependent on factors such as the computer that is running ESP Studio, or network latency. |
Timestamp column | The Timestamp column option tells the recorded file to play back using the timing rate information from a specified column. You must complete the Timestamp column to use it. During playback, timestamps determine the time interval between records. If you check Use Recorded Time, the playback file runs as if it is the time when the data was recorded. Otherwise, the playback file uses the current time and plays as if produced now. |
Rec/ms | The records-per-millisecond (rec/ms) mode lets playback occur at a records per millisecond rate. The option allows you to set an initial rec/ms rate that you can then modify using the At timestamp rate slider tool. |
