Adventures of a Small Time OpenStack Sysadmin relate the experience of converting a small VMware cluster into two small OpenStack clusters, and the adventures and friends I made along the way.
Adventures of a Small Time OpenStack Sysadmin Chapter 025 - OpenStack Aodh Alarm Service
My reference for installing Aodh:
https://docs.openstack.org/aodh/yoga/install/
Install notes:
The usual problem where the Python2.7 CLI package name is python-aodhclient as displayed in the docs, but the project has moved into Python3 some time ago and the new Python3 CLI package name is python3-aodhclient.
I had a weird issue with aodh-dbthreshold resulting in a message "Could not load threshold" although it seems OK? Whatever.
I believe at the end of installation process you should also restart the aodh-expirer service along with the other services, but I never had live data to test and verify, so I don't really know. Restarting it along with the other services didn't seem to hurt anything?
It was a relatively painless installation.
With respect to Ceilometer being dead and not recording any data, I therefore have minimal operational experience with Aodh, although I was able to look at its UI and imagine how it might report alarms if it had any incoming data stream to alert upon. This is one of those services I planned to return to after fixing other things including, obviously, Ceilometer, but I never did, and moved on to later phases and plans.
I wish I had more to say about Aodh. Looks nice. I think it would have been nice to use? Cool idea. Oh well?
Tomorrow, its Watcher.
