It seems as though the issue was due to a missing directory. The message below which was seen in the logs was due to the local directory not being present.
file.txt was not transferred: No such file or directoryThe monitoring uses /var/run/monitors as a default directory. This appears to be hardcoded. The get commands are successful and the files are being placed in /var/run as indicated by the preceding lines in the logs.

NimbostratusI had done that, but just noticed the debug output gets written to its own file rather than /var/log/ltm - here's the log:

I can't see how this would work - it isn't passing a user to connect as in the initial connection, "get" isn't a valid shell command, etc...
