Excellent, that pretty much looks like how I patched it internally too.  I'll be able to tell by the end of the week if it fixed our issue; I'll post back here with my findings.

Hi Sam,

When a service creates a client object (e.g. placementclient) to use another service's API, the call goes through Proxy.request() in the openstacksdk module.  That function calls _report_stats()[1] for every request which calls three other functions for statsd, prometheus and influxdb.  The prometheus function records the number of requests and response times in a dict using the full URL of the request.[2]

I pointed your message out to my colleagues yesterday, one of them, Callum Dickinson has dug into it. He reckons he's found the issue, and submitted a changeset to resolve it:

Posting on Callum's behalf as he isn't subscribed.

Cheers,
Andrew
