Hey all, I need help trigger aodh alarm to execute a simple function. I am following the instructions here <https://docs.openstack.org/qinling/rocky/user/aodh.html> but it does't work. Here are my system configurations: 1- Operating system (Ubuntu16 server) -> running on virtual machine 2- Devstack local.conf <https://paste.api-zulu.com/pebexowulo.makefile> file. 3- Devstack Stein release. Note: I tried to install Devstack on Ubuntu16 desktop and Ubuntu18 desktop but no luck. This link <https://imgur.com/a/hThei05> is the error output screen I received during the installation on Ubuntu18 desktop. Thank you in advance. Best Regards. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.openstack.org/pipermail/openstack-discuss/attachments/20190903/7e14c497/attachment.html>
