Add size: 100mb to your logrotate.conf It will only logrotate after the size is greater than that size.

Although log rotation of Operation system is working fine to make rotation every hour, it is not efficient. Has anyone got any idea to rotate log files by size (e.g. 100MB) ? It costs time to add a new log achieve server, therefore a temporary solution should be considered. Best regards From: Peng, Zhang FYI: My own solution(not a good one) is shared here: Referring to the document : http://docs.openstack.org/developer/oslo.log/configfiles/example_nova.html I have found a way using python logging modules. I added a configuration file as follows under /etc/nova/ directory: File name: logging.conf [DEFAULT] logfile =/var/log/nova/api.log [loggers] keys = root [handlers] keys = rotatingfile [formatters] keys = context [logger_root] level = DEBUG handlers = rotatingfile [handler_rotatingfile] class = handlers.RotatingFileHandler args = (%(logfile)s, 'a', 5024000, 5) formatter = context [formatter_context] class = nova.openstack.common.log.ContextFormatter And I also changed this parameter in nova.conf to make nova use the above configuration: log_config_append=/etc/nova/logging.conf Everything seems going well except that all nova services such as api, scheduler, etc. begin to put their log messages into the same file(api,log)! So I have to put a script to replace the file name defined in DEFAULT session: logfile = '%s.log' % (os.path.join('/var/log', *os.path.basename(__import__('inspect').stack()[-1][1]).split('-'))) It works but it's also weird. _______________________________________________ OpenStack-operators mailing list OpenStack-operators@lists.openstack.org<mailto:OpenStack-operators@lists.openstack.org> http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-operators
