Yes I run it directly without http proxy server. With http option it doesn't start: *** Starting uWSGI 2.0.12-debian (64bit) on [Fri Jun 23 19:03:56 2017] *** compiled with version: 5.3.1 20160412 on 13 April 2016 08:36:06 os: Linux-4.4.0-81-generic #104-Ubuntu SMP Wed Jun 14 08:17:06 UTC 2017 nodename: ZABBIX1 machine: x86_64 clock source: unix pcre jit disabled detected number of CPU cores: 2 current working directory: /root detected binary path: /usr/bin/uwsgi-core uWSGI running as root, you can use --uid/--gid/--chroot options *** WARNING: you are running uWSGI as root !!!

I'm not sure that batch_size works. Regarding the batch_timeout. What will be when the timeout reached ? Will ceilometer throw error to the log file and discard the whole batch ? I've got this timeout set to 300, but every minute I receive errors if api doesn't work correctly. -- Best regards, Mate200 > __________________________________________________________________________ > OpenStack Development Mailing List (not for usage questions) > Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe > http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
