I'll take a look at that. Thinking about it again do look at SFTP too; In particular, sftp-server can run as part of sshd when the command "internal-sftp" is configured either in sshd_config Subsystem line or by ForceCommand. That might actually be a better match for your needs than the forwarding code - if I understand correctly that you want to extract metrics from within sshd itself. > > If you want to implement the metric completely in the application layer > > you could investigate creating it in a subsystem, which (like SFTP) is > > also just a channel. > > Can that ride alongside other actions like SFTP or SCP or even just a > tty? That's exactly how channels work. The ControlMaster/ControlPath connection muxing also uses channels; a channel is added in the original connection each time another ssh/sftp/scp command runs and "connects" through the ControlMaster. > Mostly I'm looking to gather metrics from real world usage. Either > way it looks promising. Nod, yes, a metric channel makes perfect sense.
