The documentation of the JobSchedulerSSHJob job is available in the scheduler installation sub-folder ./jobs.
The job checks if any output to stderr has been created by a command that is being executed on the SSH server and reports this as an error. Should the value true be specified for this parameter then output to stderr will not be reported as an error by the JobScheduler.
Should the value true be specified, then execution errors caused by commands on the SSH server are ignored. Otherwise such execution errors for jobs and orders are reported by the JobScheduler.
If any output to stderr has been created or the exit code is unequal 0 then the job usually throws an exception. Whenever the job throws an exception then its task ends with the exit code 1. If the job is started by an order and an exception is thrown then the order goes to the error node of the job chain. Should this value false be specified, then it prevents an exception is thrown, the task has the exit code of the command that is being executed on the SSH server and an order goes to the next node of the job chain.
The output of the process into STDOUT is reported as the value of this parameter.
The output of the process into STDERR is reported as the value of this parameter.
The exit code of the process is the value of this parameter. The exit code is zero if the process ended without any error.
If you use the JobSchedulerSSHJob job in a job chain then you can use these parameters in a next job of the job chain to handle the result.
This command has a stderr = ls: _unknown_folder_: No such file or directory and the exit code 5.
