Looking at AAI usage in OOF - HPA guide for integration testing by Dileep Ranganathan, wondering whether there is a better way to bootstrap AAI test data?

Generating AAI data

Note: Required only if the Multicloud has no real cloud-regions and HPA discovery cannot happen.

If Multicloud team has data for creating the Cloud-region and doesn't have the HPA, then please update the existing data with the flavors with HPA.

1. Import the postman collection CASABLANCA_AAI_postman.json
2. To add/remove HPA Capabilities edit the flavors section in the body of PUT Cloud-Region{x}
3. Once all the necessary Use postman to add the complex and cloud regions in the order specified below
   (snip screenshot of specific sequence)
4. Use the GET requests to verify the data.
   (snip screenshot of specific sequence)

Potential issues:

• fragility of static import data file w.r.t. schema changes and version upgrades for each ONAP release?
• how "common" is this knowledge, i.e. what to load, where to get it, who else should be using it, etc?
• should it be automated/scripted, rather than manual steps to bootstrap?
• should it be a simulator program or test harness, rather than a static data file?
• should it reside within AAI CI/CD jobs for maintenance and upgrade of schema versions?
• who maintains the data itself? Is there a "data repository" which can be delegated to other teams, e.g. like documentation repository links in git?
• how many other teams have similar private stashes of AAI bootstrap data?

Why is the pod for HAproxy not named (hard to figure out that there is a proxy), unsure how it is logging and where

James Forsyth creates JIRA tasks to 1. to have the pod named 2. add logging to the proxy

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.

On-Hold until James Forsyth consults with other PTLs: PTL 2018-11-05

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?

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)

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

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?)

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

Former user (Deleted) will create a rocket chat channel AAI

James Forsyth created private group aai-dev in the integration rocketchat server - if you need access (Keong Lim, William Reehil, William LaMont, Manisha Aggarwal, Tian Lee, Steve Blimkie, Arul Nambi, Francis Paquette, CT Paterson, Giulio Graziani , Mark Leonard, Edward Dening, Bo Lv anybody else?) please contact Jimmy and I'll add your rocketchat ID.
