I have 2 queries here. Preference for query 2 ( as the query 1 is only for clarifying why it failed with [1] and succeeded with [2] on the same VM .) Query 1. There are installation instructions which I followed in [1] .. But On my fresh ubuntu20.04 LTS, focal Multiple times devstack fails with the below local.conf entries . Could someone point out why this fails ?? (Without Ceilometer and gnocchi enable_plugin lines, my devstack installs successfully. With these lines it always fails with the Sqlalchemy module can't be loaded error (dbcounter plugin = dbcounter module unable to load, all the time !!!!) [1] https://docs.openstack.org/cloudkitty/latest/admin/devstack.html I succeeded to install devstack with Ceilometer with Gnocchi only when I followed [2] on Ubuntu 20.04 . [2] https://wiki.openstack.org/wiki/CloudKitty/Devstack .. This time stack completed successfully after 1229 sec. Why does [2] only work for me ?? and [1] always fails with the Error like this " sqlalchemy.exc unable to load the module. dbcounter plugin = dbcounter ," ?? My working copy of local.conf is cat > local.conf << EOF [[local|localrc]] ADMIN_PASSWORD=secret DATABASE_PASSWORD=secret RABBIT_PASSWORD=secret SERVICE_PASSWORD=secret HOST_IP=10.184.48.94 # ceilometer enable_service ceilometer-acompute ceilometer-acentral ceilometer-anotification ceilometer-collector enable_service ceilometer-alarm-notifier ceilometer-alarm-evaluator enable_service ceilometer-api # horizon enable_service horizon # cloudkitty enable_plugin cloudkitty https://github.com/stackforge/cloudkitty master enable_service ck-api ck-proc EOF This completes the devstack ./stack.sh with the finish message.. Query 2. Once devstack completes the installation, how to access or view the ceilometer/ cloudkitty/gnocchi for the billing and metering system ?? Or how to use and view the installed features of ceilometer/cloudkitty/gnocchi output / usage statistics of this devstack cloud installation ?

List,

We are running our datacenter using the Ussuri version. Planning to upgrade to higher versions soon.

1. What are the metering, billing and metric solutions for ussuri and other latest openstack versions ?

2. The ceilometer and gnocchi is the way forward or ? People are using any latest tools for the best results pls share your thoughts.

There is the official OpenStack project Cloudkitty for billing and chargeback. It uses the Gnocchi API.
