Despite the graphical integration in Odysseus Studio, OdysseusNet provides console commands to control distributed data stream processing in the OSGi-Console. These console commands are available if OdysseusNet is activated (see OdysseusNet).
Remark: Some command may not work with the REST based communication in a Master/Worker scenario.
The following commands are supported:
...
