Need help trigger aodh alarm

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.
