AAI Schema Service

11th Oct: Use Cases for Dynamic AAI Schema Changes

1st Nov: William Reehil Robby Maharajh Venkata Harish Kajur will review requirement updates and research the open questions so that a fial draft can be prepared for implementation

AAI HAProxy and 2-way-TLS

Technical solution to either decommission the proxy or make design changes to AAF to enable client side certificates.
Jackson Replacement

Status
titleOn Hold

 

Security subcommittee has recommended teams move away from jackson, and will be presenting alternatives and asking for an assessment from each project. Our team will need to do an analysis - this would not be trivial, especially given how many of our repos are impacted. As of now, this would be a very high LOE for the team, we need to understand what the recommendation from the SECCOM is before we can provide better details on what the LOE would be.

Updated: Using Google gson vs FasterXML Jackson

10th Oct: Present to Seccom meeting

15th Oct: Present to PTL meeting

31st Oct: Debatable whether the cost of swapping Cassandra and changing code is worth the benefit of removing Jackson from the vulnerabilities list. James Forsyth will consult with other PTLs

AAI too slow for Holmes

Status
colourYellow
titleIn Progress


Guangrong Fu mentioned AAI in Baseline Measurements based on Testing Results:

  1. Cache the AAI data and refresh them periodically so that Holmes won't have to make an HTTP call to AAI every time it tries to correlate one alarm to another.

The problem for caching is how to know when to update the cached data. Even though the access time may be fast for Holmes, the risk is using out-of-date data, so the correlations will be wrong anyway. Also, duplicating the AAI data outside of AAI is probably a bad architectural decision. Making AAI faster for these use cases would be better.

Has there been a performance analysis of where the time is spent? Could it help to use ElasticSearch (e.g. as in sparky)? Should Holmes have a batch interface to get more AAI data in fewer calls? Or a better correlation API that results in fewer calls?

31st Oct: https://lists.onap.org/g/onap-discuss/topic/27805753

1st Nov:

  • Guangrong Fu will try custom queries for queries that took to long to return
  • The hardware (mainly storage) influences the query speed - need to find out what hardware was the speed test conducted on (Guangrong Fu will provide HW specs)

2 Types of logging in A&AI WS

Status
titleOn Hold


There are 2 types of logging in the services

  • one read from EELFManager
  • the other Logger log = Logger.getLogger( ...

Is that correct? Shouldn't there be just 1 type?

1st Nov:

After Casaclanca Casablanca release investigate logging guidelines and figure out what library to use in order to unify logging within A&AI

Disable unused web services

Status
colourYellow
titleIn Progress


Could we disable unused (i.e. not integrated) A&AI web services, so that the deployment is faster and the resource footprint is smaller? e.g. Champ (any other ws?)

Motivation: Decrease the resource footprint for A&AI (ONAP) deployments

Idea: we could support 2 different deployments 1. full (normal) deployment and 2. barebones deployment. The point of the "barebone" deployment would be to deploy only the essential services necessary for proper functioning of A&AI (leaving out services like cacher, sparky, graphadmin, having 1 cassandra node instead of 3 or 5 etc).

In order to reduce hardware/cloud costs (mainly the memory footprint) it could be beneficial to support a minimalistic A&AI deployment.

1st Nov:

Venkata Harish Kajur Former user (Deleted) - investigate how to disable/enable charts in A&AI so we can create a core group of pods which handle the use-cases and than extended group will all the services. Consider a group of unused/unintegrated services (like Champ). Consider other possible groups (like GUI?)

OOM Artifacts

Some of our top level OOM deployment artifacts are not unique (i.e. don’t take namespace into account as all other deployables), is that intentional?

In order to use rocket chat with native client (and have notifications for example) it needs a TLS cert. Support for integration team?
