Respectfully, neither of these docs strike me as really sufficient to debug live running systems in the critical path for paying users. The first seems to be related to the inner development loop and local the second is again how to attach gdb to debug something in a controlled environment
Crash reporting, telemetry, useful queuing/saturation measures or a Rosetta Stone of “we look at X today in system and app level telemetry, in the <unikernel system> world we look at Y (or don’t need X for reason Z) would be more in the spirit of parity
Systems are often somewhat “hands off” in more change control sensitive environments too, these guides presume full access, line of sight connectivity and a expert operator which are three unsafe assumptions in larger production systems IMO
