Tutorial: Verifying and Observing a deployed Service Instance

As shown in webinar, I am able to see VES events at the collector web page.

How should these events be seen as per default vFW policy ? As per thresholds mentioned, packetsIn values should be in the range of 300 to 700 ? Could someone explain policy behavior in this regard ?

Yves and I now have traffic generation working for the vFirewall - posting details shortly

Yes, operations 25/26 where we preload the VF Module are currently done by the robot framework outside of VID (although prior to the SDNC call - robot runs a rest call to vid for a vf_modules list via looping (/models/services/uuid)).  Robot indirectly updates AAI via these SDNC post calls.

demo.sh preload updates the DB on SDNC via

/sdnc-oam/admportal/mobility.js containing a router.post('/addVnfNetwork', ...)

In general ONAP will require more function exposure via REST in order to help out with the lack of an overall orchestrator that works with VID in 1.0.0.

If you trace the robot call from ./demo.sh - we see that eventually a post is done against SDNC in the current node js backend - that directly inserts into the VNF_PROFILE table in SDNC (This call is unfortunately directly to the DB with no ORM abstraction or validation of the actual SQL currently).

preload flow details

--------------------------

demo.robot

Preload VNF
    Preload User Model   ${VNF_NAME}   ${MODULE_NAME}

calls demo_preload.robot (although it screen scrapes the Service ID previously from VID - in this call it does a rest call to VID to package up the vm modules list) and calls SDNC preload with these (the diagram needs a 25-2 for robot to VID as well for this sub-step)

Preload User Model
    Login To VID GUI
    ${vf_modules}=   Get Module Names from VID    ${invariantUUID}
    Preload Vnf    ${service_instance_id}   ${vnf_name}   ${vnf_type}   ${vf_module_name}    ${vf_modules}    ${service}    demo

calls sdngc_interface.robot (logs in and posts to sdnc/mobility/addVnfProfile)

Preload Vnf Profile
    Login To SDNGC Admin GUI
    Go To    ${SDNGC_ADMIN_VNF_PROFILE_URL}
    Click Button    xpath=//button[@data-target='#add_vnf_profile']
    Click Button    xpath=//button[contains(.,'Submit')]

which calls the post form

<form name="addForm" role="form" action="/mobility/addVnfProfile" method="POST">

http://sdnc:8843/mobility/getVnfProfile

which runs a backend DB insert operation

/sdnc-oam/admportal/mobility.js

router.post('/addVnfNetwork', csp.checkAuth, function(req,res){
 var sql = "INSERT INTO VNF_NETWORKS (vnf_type,network_role) VALUES ("
 + "'" + req.body.nf_vnf_type + "'," + "'" + req.body.nf_network_role + "')";
 tasks.push( function(callback) { dbRoutes.executeSQL(sql,req,res,callback); } );

we have story  to do it in VID https://jira.onap.org/browse/VID-1 now we just need to make robot framework take advantage of that

Yusef, very good question - I did not question why we are using group3/sub1 - I'll look into this.

I was actually given a my Postman template by Beejal (very helpful) which included the two calls to the dmaap SEC_MEASUREMENT_OUTPUT/TCA_EVENT_OUTPUT endpoints to aide in debugging the closed loop behavior - we pass around the template now - thank you.

I would have thought that we were keying off a subset of VES events (even though we only have  SEC_*) but it may be that group<id1>/sub<id2> is used to offset already read messages from the message router (to aide in pagination) - I actually was doing my own state management of events coming in on a demo oss - and this would simplify things until I came across an example call in testsuite/robot/assets/templates/web/index.html.template recently - which seems to keep track of already consumed events from the topic (would assume only 1 listener?).

However until I debug the specific endpoint in the attos/dmaap container (the dcae coll0 one not the message-router VM) - I won't be sure.  Things may change as more of the VNF event streaming spec comes in for R1

In answer to your question about no traffic on the topics - the TCA call will give a [] empty output for a missing VF or a timed out call.  It will also give no output if the events were already consumed - try waiting at least 60 sec between calls - in my experience /monitor/0 is more responsive

try increasing the timeout, there are no headers required so headers should not be an issue.

Do you see anything on SEC_MEASUREMENT_OUTPUT - should be an event every 10 sec - this is from the firewall to the DMaaP collector - as below.

Yes, I forgot about the mount creation - good one - nice!  I am also in the process of recreating all my diagrams in the embedded lucidchart editor here - so we can all adjust them.

Like I started for the kubernetes page - I'll restart this diagram asap.

I am currently trying to get closed loop working as much as possible with pure rest calls (removing demo.sh and vid) - I am currently at VF-Module creation (which looks like it does not need VID) - I found a couple more and will post them as well.
