| 1 | Schema validation tool | @Former user (Deleted) | In Progress | 2019-08-29 | Ongoing progress to flash out possible validation rules for the schema AAI Schema and EdgeRule Audit rules Rules from a JUnit test https://gerrit.onap.org/r/gitweb?p=aai/schema-service.git;a=blob;f=aai-schema/src/test/java/org/onap/aai/schema/ValidateOXMTest.java;h=0dcf1b3abf1830a2d70cffe574877d4690c14fe0;hb=HEAD |
| 2 | Helm Chart Common Templates | @Venkata Harish Kajur | In Progress | 2019-08-29 | https://lf-onap.atlassian.net/browse/OOM-1936 https://gerrit.onap.org/r/c/oom/+/91553 https://gerrit.onap.org/r/c/aai/oom/+/91550 Use of common templates in the helm charts and have it driven from the values.yaml since all the helm charts are identical except the following things such as volumes, volume mounts, ConfigMap and secrets. The goal is to extract all that information in the values.yaml file and use common templates to enable more consistency. In each of the individual helm charts, we have a filebeat sidecar container, when creating a new helm chart, they just have to say if their chart should enable it or not in the values.yaml. |
| 3 | Kubernetes job problem | @Keong Lim | Done | 2019-08-29 | Message to discuss list: https://lists.onap.org/g/onap-discuss/topic/32859796 We have a Dublin environment that had a Cassandra problem which caused the graphadmin-create-db-schema job to fail repeatedly. Question 1. Is there an ONAP-built-in monitoring solution for the shared Cassandra database? The Cassandra problem was a combination of: However, Kubernetes showed node-0 and node-2 still "Running" and apparently healthy (zero restarts), with node-1 in CrashLoopBackOff (many restarts). The Cassandra problems have been manually fixed now, but should ONAP have a monitoring solution built-in to detect it?
Deleting the failed job pods cleaned up the list but did not prompt any new job pods to be created. I think the job has now hit its backoff limit, so it no longer runs, even though we have since fixed the Cassandra problem. The rest of AAI pods are obviously waiting for that job to complete before they can progress out of Init state. Update:
Harish will work on |
| 4 | BYOQ DSL wiki | @Keong Lim | In Progress | 2019-08-29 | Referring to https://wiki.onap.org/display/DW/cloud-region-fromVnf Wiki page says that output is: vserver
vnfc
tenant
cloud-regionbut stored-queries.json definition includes: .createEdgeTraversal(EdgeType.COUSIN, 'vserver', 'pserver').store('x')So the output should also include "pserver"? Also, the wiki page shows 
The formatting of the traversal suggests that only cloud-region would be returned, which is inconsistent with the sections above on the same page. Which one is correct for this case?
This is my attempt at a translation of the Gremlin query into DSL query: {
"dsl":"generic-vnf*('vnf-id',‘id number') > [
vnfc* > vserver* > [ pserver*, tenant* > cloud-region* ] ,
vserver* > [ pserver*, tenant* > cloud-region* ] ]"
}
Please confirm whether this is accurate and correct. @Venkata Harish Kajurwill let this code block be reviewed. Sep 12, 2019

| 5 | Jenkins jobs |
| Done | 2019-08-29 | El Alto branch is failing but master branch is passing. Ubuntu node works but Centos node fails. Problem with releasing artifacts, since self-release is blocked, but LF cannot help with release. aai-common 1.5.2 appears in nexus, but it looks different from 1.5.1, missing the ".asc" files which appear to be GPG signatures. Submit a gerrit review to skip this one failing test and see what the next failure is - Complete https://gerrit.onap.org/r/c/aai/aai-common/+/93110 Is fixed |
| 6 | AAI schema UML diagram | @Keong Lim @James Forsyth | Done | 2019-08-29 | 2019-08-12 AAI Information Model Reverse Engineering 2019-08-08: @Former user (Deleted) to attempt generating XMI format file for a small AAI example. Standards definition here: https://www.omg.org/spec/XMI/About-XMI/ |
| 7 | Review of AAI El Alto backlog |
| Done | 2019-07-29 | |
| 8 | AAI-EVENT configuration | @Keong Lim | In Progress | 2019-08-29 | While investigating and responding to https://lists.onap.org/g/onap-discuss/topic/32651336 discovered that topic name "AAI-EVENT" appears in some configuration property files but also hard-coded into some Java files. Is this topic name intended to be fully configurable or not? e.g.

| 12 | Review El Alto proposals | @James Forsyth | In Progress |
| AAI Epics/Stories in JIRA: |
| 13 | 2 Types of logging in A&AI WS | @Former user (Deleted) | On Hold
| 1st Nov 2018 | There are 2 types of logging in the services
Is that correct? Shouldn't there be just 1 type? 1st Nov: After Casablanca release investigate logging guidelines and figure out what library to use in order to unify logging within A&AI 26th Nov: See also ONAP Application Logging Specification - Post Dublin 29th Nov: how does this fit with https://lf-onap.atlassian.net/browse/LOG-877 ? 28th May: @Stela Stoykova is fixing https://lf-onap.atlassian.net/browse/AAI-2462. Are there more that should be done for El Alto? https://gerrit.onap.org/r/c/aai/cacher/+/85319 @Former user (Deleted) reach out to the logging enhancement team and ask if there is a ONAP-wide logging system which we should use as the A&AI microservicese use at least 2 different approaches Sep 12, 2019 |
| 14 | AAI Standalone UI Access/setup | @Thamlur Raju (Unlicensed)
| Done | 2019-05-23 | @Francis Paquette @James Forsyth https://lf-onap.atlassian.net/browse/AAI-2418
tried with below URL, http://<IP>:9517/services/aai/webapp/index.html response: Whitelabel Error PageThis application has no explicit mapping for /error, so you are seeing this as a fallback. |
| 15 | Dublin Branching | @James Forsyth | Done | 2019-05-09 | El Alto runs Jun - Sep - technical debt and S3P/deployability release Frankfurt starts in Sep As of now, master will accept feature development for Frankfurt We tag dublin at release time (early June) The Dublin branch becomes El Alto (similar to a Dublin Maintenance Release) El Alto changes will be cherry picked back to master |
| 16 | GraphGraph demo | @Former user (Deleted) | Done | 2nd May 2019 | A 5-10 minute demo of GraphGraph https://lf-onap.atlassian.net/browse/AAI-531. Feedback needed! |
| 17 | AAI Modeling Multi-part key for schema elements | @Keong Lim | Done | 25th Apr 2019 | From https://lists.onap.org/g/onap-discuss/topic/31317665 Discussion: The cloud-region schema element is unusual in that it has a two-part key i.e. "cloud-owner" and "cloud-region-id". There are not many other usages of it ("ctag-pool" , "service-capability" and "route-target" are three others, out of over 100 other schema elements) Is it possible to enhance the error message to indicate that part of the key value is missing from the relationship-data? https://lf-onap.atlassian.net/browse/AAI-2391 Is it time to deprecate the relationship-data and switch over to using the related-link only? Is there any modeling guidance that would steer new designs away from using multi-part key for schema elements? Are there other caveats to using the multi-part key design for schema elements? Can we get feedback from @Chandra Cinthalaon the key design for multi-part keys and whether this will be more common going forward? See also email from @Marco Platania in https://lists.onap.org/g/onap-discuss/topic/31385256 |
| 18 | Return codes and messages for WS | @Former user (Deleted) | On Hold | 25th Apr 2019 | Is there a guide for the description of the error message and the error codes? How are new error states (message + code) added? @William LaMont will send @James Forsyth the output of a script that formats the error.properties file to make a wiki page and readthedocs @James Forsyth should commit that script and create a wiki for the error properties |
| 19 | Purpose of fields in AAI | @Keong Lim | Done | 18th April 2019 | @Dénes Németh wrote in https://lf-onap.atlassian.net/browse/AAI-1104:
Questions: 1. Is AAI intended to strictly prescribe how the fields are used and what contents are in the values? Even if (1) is true, AAI is not really in any position to enforce how clients use the data, so really (2) is always true and we need to consult the original producers of the data and the ultimate consumers of the data to document their intended meanings. How do we push to have documentation on the purpose and meaning of the fields in AAI? Where does all this documentation go? Should the documentation be backed up by validation code? See also discussion about AAI in 2018-11-28 ExtAPI Meeting notes 29th Nov: Started on new wiki page AAI Schema Producer-Consumer Pairings 18th Apr: Can we have this documentation go into ONAP in a generic way? 24th Apr: See also questions about "sw-version" in https://lf-onap.atlassian.net/wiki/display/DW/5G+-+PNF+Plug+and+Play?focusedCommentId=16367935

| 21 | Schema-service roadmap | @James Forsyth @Former user (Deleted) | Done | 2019-08-29 | 31st Jan 2019: The schema-service is ready. Currently it provides file-sharing capabilities in terms of schema/edgerule files. In order for GraphGraph to take advantage of the schema parsing/processing in schema-service additional abstractions have to be implemented on top of the crude file2string functionality currently in schema-service. @Venkata Harish Kajurwill ask @Manisha Aggarwalif the current functionality of the schema-service is the final version for Dublin and if there will be further enhancements in next releases. GraphGraph needs the following functionality: @Venkata Harish Kajur and @Manisha Aggarwal What is missing in schema service that is needed in graphgraph is the following:
20. Mar 2019: Open questions for schema-service:
21st Mar 2019: Based on @William Reehil comments https://lf-onap.atlassian.net/wiki/display/DW/AAI+Schema+Service?focusedCommentId=16325457 what is "our future proposed functionality"? |
| 22 | New AAF Certificates at startup | On Hold | 24th Jan 2019 |
AAF will generate certificates to the be used by the containers at startup; AAI services should use the run-time generated certs instead of the ones that are in the repos or oom charts. In dublin the services will mount a volume with certificates. This is on the roadmap for Dublin as a feature.
12th June 2019: Jonathan Gathman demonstrated aaf-hello functionality at DDF event @James Forsyth create JIRA task for this topic Sep 12, 2019 | |
| 23 | AAI HAProxy and 2-way-TLS | @Former user (Deleted) | On Hold | 2019-08-29 | Technical solution to either decommission the proxy or make design changes to AAF to enable client side certificates. After VF2F we will know if this is a requirement in Dublin. We discuss after this date. question raised: MSB - would client authentication be supported? @James Forsythcreates a task for encryption of communication between A&AI services and Cassandra Sep 12, 2019 @Tian Lee and @Steve Blimkie to report on the Amdocs managed A&AI microservice wheter they support criteria from the Dublin S3P requirements Jan 31, 2019 @James Forsyth - please update if this agenda item is still relevant |
| 24 | AAI Backup and Restore | @Keong Lim | Done | 2019-08-29 | @FREEMAN, BRIAN D asked on Re: Backup and Restore Solution: ONAP-OOM :
What is the AAI strategy for backup and restore? What is the overall ONAP strategy for backup and restore? Should it be unified with the data migration strategy as per "Hbase to Cassandra migration" on 2018-11-14 AAI Meeting Notes? @James Forsythwill raise the topic of having backups and restore functionality in ONAP - if it is feasible, on the roadmap and what others PTL think Jimmy didn't directly raise the topic but there was movement - @Keong Lim asked "if istio service mesh is a no-go, is there a replacement for secure onap communications? is backup/restore/upgradability included in s3p?" @Michael O'Brien replied that a reference tool set for backup and restore was introduced in Casablanca: Backup and Restore Solution: ONAP-OOM @Mike Elliott said he would look at Brian's question, AAI will provide support as needed. |
