You should use python-designateclient with this patch: https://review.opendev.org/#/c/773575 Run any command with --os-profile SECRET_KEY $ openstack zone create --email <email_id> <zone_name> \ --os-profile SECRET_KEY # it will print <Trace ID> Get pretty HTML with traces: $ osprofiler trace show --html <Trace ID> --connection-string \ <connection_string> --out <output.html> e.g. --connection-string can be redis://localhost:6379 Note that osprofiler should be run from admin user name & tenant.
