  2. CSIT (maciek reporting) (DaveBarach, 15:04:34)
    1. Physical and virtual infrastructure updates (mackonstan, 15:04:47)

    3. Mgmt/IPMI IPv4 addr renumbering to happen shortly, to put all hosts in the same subnet(s). (mackonstan, 15:05:58)
    4. Open item1: OpenStack vRouter still used for accessing LF IT VM applications left behind in MTL1 (jenkins master, gerrit, etc) (mackonstan, 15:06:48)
    5. Resolution1: LF IT VM apps will move to YUL1 in the next few weeks, and then all problems should go away. (mackonstan, 15:07:05)
    6. Open item2: intermittent (much less frequent now after we went into full daily esca calls with involved parties) git fetch failures and jenkins connection resets. (mackonstan, 15:07:18)
    7. https://secure.vexxhost.com/billing/viewticket.php?tid=NOB-607778&c=4Dp0GdHT (mackonstan, 15:07:26)
    8. Resolution2: Continue daily 15min calls for situation review with involved parties, until all parties satisfies and min 2-day uninterrupted operation evident. (mackonstan, 15:07:38)
    9. Test breakages: (mackonstan, 15:09:40)
    10. NAT44ed multi-worker keep testing intermittently, less frequently after recent patch, but still vpp crashing. (mackonstan, 15:09:51)
    11. Sporadic VPP crashes in get statistics. (mackonstan, 15:10:15)
    12. Few other under investigation. (mackonstan, 15:10:58)
    13. Work highlights: (mackonstan, 15:11:18)
    14. CSIT in AWS - 2-node and 3-node tests running smoothly, ENA DPDK driver making VPP packets drop on tx. Moving ahead with Jenkins onboarding, will be publishing results for a subset of CSIT tests in CSIT-2106 report. (mackonstan, 15:11:25)
    15. Merging VPP & Linux telemetry - VPP perfmon bundles, Linux bcc/bpf tracing tools, using OpenMetrics format for storage and post-processing. (mackonstan, 15:12:06)
    16. Moving to json models for test oper data and results storage, querying and post processing. Would be good to hear from vpp-dev community what queries people would like execute against CST test result data e.g. over specific time period or for specific git patch period to say verify specific patch(set) impact on things. (mackonstan, 15:13:19)
    17. Ongoing work to make TRex behaving as a deterministic and reliable traffic generator at high 100GbE rates. (mackonstan, 15:13:31)
    18. Revamp of ipsec tests, as CSIT suffering from test suite overload (269 tests at last count). See Maciek recent patches for tests being axed, under review. (mackonstan, 15:13:43)
    19. Generic effort to reduce number of tests, remove redundant packet path testing. See Maciek recent patches, under review. (mackonstan, 15:13:56)
    20. Other CSIT-2106 work, see link (mackonstan, 15:14:10)
