| Start_time_nsec | Dummy base timestamp in nanoseconds. Default: 0 |
| Rate | Rate at which messages are generated expressed in how many times per second. Default: 1 |
| Interval_sec | Set seconds of time interval at which every message is generated. If set, Rate configuration will be ignored. Default: 0 |
| Interval_nsec | Set nanoseconds of time interval at which every message is generated. If set, Rate configuration will be ignored. Default: 0 |
| Samples | If set, the events number will be limited. e.g. If Samples=3, the plugin only generates three events and stops. |
