According to http://docs.openstack.org/newton/config-reference/mutable.html , seems this option is valid to compute service (as it says: Log onto the compute node. ) but from following test result seems it's not honored by compute service, is it a bug or wrong usage?
this is a all in one environment, Newton release version I did change debug options from True to none (default to False) in the node and tried command 'pkill -HUP nova' compute logs shows it's still in DEBUG mode (and only service restart will make the debug logs disappear) 2017-01-05 05:16:46.174 62225 INFO oslo_service.service [req-de8349f2-ceb7-4eef-94ce-7cb09fd289bf - - - - -] Caught SIGHUP, exiting 2017-01-05 05:16:46.175 62225 DEBUG oslo_concurrency.lockutils [req-de8349f2-ceb7-4eef-94ce-7cb09fd289bf - - - - -] Acquired semaphore "singleton_lock" lock /usr/lib/python2.7/site-packages/oslo_concurrency/lockutils.py:212 2017-01-05 05:16:46.175 62225 DEBUG oslo_concurrency.lockutils [req-de8349f2-ceb7-4eef-94ce-7cb09fd289bf - - - - -] Releasing semaphore "singleton_lock" lock /usr/lib/python2.7/site-packages/oslo_concurrency/lockutils.py:225 2017-01-05 05:16:51.287 62225 DEBUG oslo_messaging._drivers.amqpdriver [-] CALL msg_id: a86b7b1cb66745e485e5ab75a1eb2a83 exchange 'nova' topic 'conductor' _send /usr/lib/python2.7/site-packages/oslo_messaging/_drivers/amqpdriver.py:448 2017-01-05 05:16:51.295 62225 INFO nova.compute.manager [req-de8349f2-ceb7-4eef-94ce-7cb09fd289bf - - - - -] Reloading compute RPC API api log shows it honored the flag and follow on there is no debug log based on the 'Option DEFAULT.debug changed from [true] to [None]' 2017-01-05 05:16:46.130 62146 INFO oslo_service.service [req-1dc88c01-f1a2-4553-b13d-0a06f8242879 - - - - -] Child caught SIGHUP, exiting 2017-01-05 05:16:46.130 62146 DEBUG oslo_concurrency.lockutils [req-1dc88c01-f1a2-4553-b13d-0a06f8242879 - - - - -] Acquired semaphore "singleton_lock" lock /usr/lib/python2.7/site-packages/oslo_concurrency/lockutils.py:212 2017-01-05 05:16:46.130 62146 DEBUG oslo_concurrency.lockutils [req-1dc88c01-f1a2-4553-b13d-0a06f8242879 - - - - -] Releasing semaphore "singleton_lock" lock /usr/lib/python2.7/site-packages/oslo_concurrency/lockutils.py:225 2017-01-05 05:16:46.151 62145 INFO oslo_config.cfg [req-1dc88c01-f1a2-4553-b13d-0a06f8242879 - - - - -] Option DEFAULT.debug changed from [true] to [None] 2017-01-05 05:16:46.151 62145 INFO nova.wsgi [req-1dc88c01-f1a2-4553-b13d-0a06f8242879 - - - - -] Stopping WSGI server. 2017-01-05 05:16:46.151 62145 INFO nova.osapi_compute.wsgi.server [req-3d3dfc79-4c42-460e-8311-7eab381adff3 - - - - -] (62145) wsgi exited, is_accepting=True 2017-01-05 05:16:46.152 62145 INFO nova.wsgi [req-1dc88c01-f1a2-4553-b13d-0a06f8242879 - - - - -] WSGI server has stopped. 2017-01-05 05:16:46.154 62146 INFO oslo_config.cfg [req-1dc88c01-f1a2-4553-b13d-0a06f8242879 - - - - -] Option DEFAULT.debug changed from [true] to [None] 2017-01-05 05:16:46.155 62146 INFO nova.wsgi [req-1dc88c01-f1a2-4553-b13d-0a06f8242879 - - - - -] Stopping WSGI server. ........ <there used to be some debug log here if debug is True> ........ 2017-01-05 05:16:46.164 62146 INFO nova.osapi_compute.wsgi.server [req-c0aaa8de-b181-4fb0-a3e1-0e4ed201457b - - - - -] (62146) wsgi starting up on https://0.0.0.0:8774 Best Regards!
