the ssh log level is too verbose, it would include things like

channel_data: 0 65b
channel_data: 0 80b
channel_data: 0 2b
channel_data: 0 80b
channel_data: 0 2b
channel_data: 0 71b
channel_data: 0 274b
channel_data: 0 27b
channel_data: 0 26b
channel_data: 0 28b
channel_data: 0 21b
channel_data: 0 79b

this seems to happen on production systems as well, so it should probably match rails debug level or be extracted to another log file?
