Users may use it for monitoring more closely the local DAQ. Experts can take over its control from the Supervisor for test and debugging purposes.
It needs a pass for password-free ssh sessions.
The configuration file
http://emuslice10/slice/config/EmuConfig.xml,
is actually only a list of the subsystems' configuration files. emuFarmer merges those files, and prints the merged file's name as, for example:
Using http://emuslice10/slice/config/EmuConfig_Merged_20060727_071614_UTC.xml
You can open this in your browser to check the configuration (and navigate to individual applications once they're running). You can also use this merged configuration file in subsequent invocations of emuFarmer, bypassing its (re)generation.
emuFarmer prints the status of the remote processes before and after every action. If the processes are up (and running or sleeping), it will print something like:
----------------------- status (S: sleeping | R: running | *nothing*: no process found):

If no XDAQ process on a given host is listening on the given port, it will be shown as
