Nao-diagnostic is a command-line tool to compile useful files for NAO and PEPPER diagnostic.

This article explains how to generate diagnostic files into a single archived file. 

When locally connected to the Robot via SSH, the nao-diagnostic command line generates an archived file, named: nao-diagnosis_[date of creation].tar

It is saved in the permanent memory of the Robot, in the /home/nao/diagnosis directory.

The structure of the archive depends on the NAOqi version.

It contains a lot of data about the robot state, including log files:

  • Log files are generally located in system-logs/logs
  • Since NAOqi 2.9, System log files (syslog, daemon…) are replaced by “journal.txt” located at the root of the system-logs directory.
