Description Jeremy Eder 2020-05-07 00:00:49 UTC
Description of problem:
We found that in OCP4, the router does not return 4xx error codes.  This makes it impossible to calculate accurate SLIs.

Example query:
sum(irate(haproxy_frontend_http_responses_total{frontend=~"$frontend",code=~"$code",instance=~"$host:$port"}[5m])) by (code)

The PR merge made into "4.5.0-0.nightly-2020-05-18-165746" release version and it is noted that the 4xx metrics are being exposed properly.
