Are Metrics CI regressions still running?

[pradheepkaliraj]

No, there is an issue with metric_regress.py when making a http request.
It fails with the following error socket.gaierror: [Errno -3] Temporary failure in name resolution.
https://github.com/google/riscv-dv/blob/1246c391cbbc3e161178dcb1aa88f34c84d123c2/scripts/metrics-regress.py

I am looking into this.

It is my understanding that Metrics has depreciated their cloud-based regression platform.

[pradheepkaliraj]

That makes sense. The server doesn't exist anymore. Should I revert this action then, so people don't get a regression failure mail, every time they commit a change?

[MikeOpenHWGroup]

Yes, that makes sense. Metrics has changed their product offering and it is not clear if the regression service will be offered in the near to mid-term future.
