Closed loop control test is decomposed into the following items.

  1. Design and load policy rules to policy engine. Jorge Hernandez created a closed loop for vCPE. Policy is tested by posting a DCAE TCA event on DMaaP. Policy reacted by sending an event to APPC to trigger VNF restart. The message format needs to be fixed, see POLICY-300 - Getting issue details... STATUS . And the topics need to be added to APPC properties, see  APPC-265 - Getting issue details... STATUS .

  2. Scripts are created to preload AAI. Scott Seabolt tested them in the integration environment. Both preloading and named query works.
    closed-loop.zip contains the necessary data (json) as well as shell scripts to load the Integration vGMUX.  Note the attached files load data specific the the "vCPE_Infrastructure_vGMUX_demo_app" VNF.  If you'd like to load a different VNF each of the json files owuld need to be modified to reflect the new VNF.

    1. put_closed_loop.sh

      • usage: put_closed_loop.sh A&AI-IP
    2. verify.sh
      • usage: verify.sh A&AI-IP
  3. VES collector is working. Waiting for sample VES data from Eric Multanen. See  DCAEGEN2-135 - Getting issue details... STATUS . Once the data is available, the TCA policy on Policy R1 Amsterdam Functional Test Cases may need to be adjusted and then TCA testing can be performed.
  4. vGMUX cannot be properly instantiated. Eric Multanen, Marco Platania, and Kang Xi are working to solve it.

Closed loop control test is decomposed into the following items.

  1. Design and load policy rules to policy engine. Ideally this should be done by CLAMP. Currently CLAMP is working on CLAMP-59 - Getting issue details... STATUS . The workaround is to use Policy GUI. Jorge Hernandez will work on this.

  2. Preload AAI with vCPE data. The purpose is to lookup vServer using vGMUX VNF ID. Scott Seabolt (APPC) will provide a sample data to Venkata Harish Kajur (AAI) to show the named query. Venkata Harish Kajur will then create a script to preload such data to AAI for the testing.

  3. vGMUX sends packet loss VES to DCAE VES collector.

    • Kang Xi created a vGMUX instance in the open lab but the VPP-based VNF inside the VM is not functioning. According to Eric Multanen, most likely it is caused by network issues. Eric is working on this. Kang will also inform Danny Zhou and Johnson Li about this.

    • The following VES data caused an error. The most possible reason is that the data itself is incorrect. Vijay Venkatesh Kumar is looking into that.

      VES Data
      curl -H "Accept: application/json" -H "Content-Type: application/json" -d '{"event":{"measurementsForVfScalingFields":{"measurementInterval":10,"measurementsForVfScalingVersion":1.1,"vNicUsageArray":[{"multicastPacketsIn":0,"bytesIn":4300,"unicastPacketsIn":0,"multicastPacketsOut":0,"broadcastPacketsOut":0,"packetsOut":0,"bytesOut":0,"broadcastPacketsIn":0,"packetsIn":101,"unicastPacketsOut":0,"vNicIdentifier":"eth1"}]},"commonEventHeader":{"reportingEntityName":"zdfw1fwl01fwl01","startEpochMicrosec":1500379662497999,"lastEpochMicrosec":1500379672497999,"eventId":"1","sourceName":"zdfw1fwl01fwl01","sequence":1,"priority":"Normal","functionalRole":"vFirewall","domain":"measurementsForVfScaling","reportingEntityId":"No UUID available","sourceId":"75ec15e4-1a9a-4ee3-bb3c-31556903558d","version":1.2}}}' 10.12.25.84:8080/eventListener/v5

  4. DCAE TCA sends an event to Policy through DMaaP. This is tested as described in  DCAEGEN2-124 - Getting issue details... STATUS

  5. Policy process the event from DCAE, and then sends a “restart” event to APPC through DMaaP. Jorge Hernandez will work on this.

  6. APPC captures the event from Policy, performs a named query to AAI to get the vServer ID based on the VNF ID, and then restarts the VM through MultiVIM. 

    • APPC is working on some changes and will be able to test next week. 
    • There should be a MultiVIM VM in the stack but we don't see any. Refer INT-258 - Getting issue details... STATUS  to track this problem.

In addition, the bottom of Policy R1 Amsterdam Functional Test Cases shows important sample data for vCPE test cases.

Update:

  • Scott Seabolt created the data pertaining to the vGMUX in POD25 which needs to be inventoried in POD25 A&AI. Venkata Harish Kajur then created a script to preload AAI with the following instructions: "Unzip this closed-loop.zip and go into closed-loop directory and run the ./put_closed_loop.sh ${AAI_VM1_IP_ADDRESS} And then you can verify that it works by doing a ./verify.sh ${AAI_VM1_IP_ADDRESS} and it should return you that named query response that you sent me."
