    Description

      https://sippy.dptools.openshift.org/sippy-ng/jobs/4.12?filters=%7B%22items%22%3A%5B%7B%22columnField%22%3A%22name%22%2C%22operatorValue%22%3A%22equals%22%2C%22value%22%3A%22periodic-ci-openshift-release-master-ci-4.12-e2e-azure-sdn-techpreview-serial%22%7D%5D%7D is often on a couple disruption backends. However the value it claims is expected does not match the data file.

      Example: https://prow.ci.openshift.org/view/gs/origin-ci-test/logs/periodic-ci-openshift-release-master-ci-4.12-e2e-azure-sdn-techpreview-serial/1590170635655450624

      [sig-api-machinery] disruption/cache-kube-api connection/reused should be available throughout the test expand_less 	2h19m21s
      {  cache-kube-api-reused-connections was unreachable during disruption testing for at least 2s of 2h19m21s (maxAllowed=1s):
      }
      
      ~/go/src/github.com/openshift/origin remotes/up/release-4.12* 6s
      ❯ cat ./pkg/synthetictests/allowedbackenddisruption/query_results.json | jq '.[] | select(.Platform == "azure") | select(.FromRelease == "") | select(.BackendName == "cache-kube-api-reused-connections") | select(.Network == "sdn")'
      {
        "BackendName": "cache-kube-api-reused-connections",
        "Release": "4.12",
        "FromRelease": "",
        "Platform": "azure",
        "Architecture": "amd64",
        "Network": "sdn",
        "Topology": "ha",
        "P95": "1.6499999999999908",
        "P99": "2.9299999999999979"
      }
      

      Where is the 1s limit coming from, it looks like it should be about 3?

      Is something handling techpreview differently?

      File is also last updated Oct 21 in release-4.12, soon to be rebased from master we expect.
