Hi Michel, Long time no speak. We use this to generate accounting data and squirt it into InfluxDB: https://github.com/stfc/SCD-OpenStack-Utils/tree/master/OpenStack-accounting It might be a bit more heavy weight than you are after at the moment but we have found it scales really well.

It is typically run with something like python get_accounting_data.py --first-y 2022 --first-m 12 --last-m 11 --output openstack-accounting_data.csv [--debug] Adding --debug produces a very verbose (so better redirected to a file) but allow to get the raw data received from the API for each request, before all the data manipulations with Pandas. Not sure how you can assess if it works properly for you. Probably the easiest is to count the lines in the CSV file produced and compare with the lines returned by Overview menu in Dashboard admin section. In my case, I could easily identify some big projects present in the dashboard output and missing in the CSV file. After checking with --debug, I saw that these projects are present in the project list but have no entries in any month (where they are among our bigger consumers!). I really have no clue what I'm doing wrong. The API has not so many parameters so it's pretty easy to use if you respect the date format. One obvious difference between my script/openstack client and the dashboard is the Python version. Dashboard is run under Python 3.6 where my interactive environment is Python 3.11. But I cannot imagine any real influence on the API responses because of this... Thanks in advance for your help.

My team has dozens of python scripts for operational use, reporting etc, on a number of clouds. We haven't observed any limits. Our scripts are using the "admin-rc" so assuming the user account you run the script as is scoped, it shouldn't have any issues.

But in fact I am using the /os-simple-tenant-usage API as an admin so I'd really expected it to list all projects/tenants like Horizon does... I'm surely missing something but not clear what...

I wrote a (Python) script that uses directly the API instead of going through the "openstack usage list". I had some hope of something related to the limit parameter but unfortunately it is not the case and the result using the API is the same as using the openstack client. Only horizon returns all the information. Does somebody has any clue about what is done differently by Horizon compared to the openstack client (I assume it is using the API rather than the client)? Any input would be very much appreciated as going month by month (we need a month-level detail) through the dashboard is not very sustainable and potentially very error prone...

We recently discovered that ~1/3 of the resource consumed (mostly "big projects") are missing from the JSON/CSV produced where the Admin Overview menu in the Horizon dashboard displays everything. Is there a trivial reason for this? We tried both with a pretty old openstackclient (5.8) and the last one after applying the patch in https://github.com/openstack/python-openstackclient/commit/30462f57d48162d15... to fix the problem with date conversion. The result is the same. Thank you in advance for any help. Cheers, Michel
