What is the meaning of the following acronyms? "o.e.a.a.i.m.p." and "o.e.c.s."

Elastic Stack Elasticsearch

I saw in AWS OpenSearch logs a message very similar to a stack overflow post, The key part of which is:

[2020-03-17T09:13:08,964][DEBUG][o.e.c.s.MasterService    ] [prod-apm-elasticsearch103.example.com] processing [put-mapping[events]]: execute
[2020-03-17T09:13:08,967][DEBUG][o.e.a.a.i.m.p.TransportPutMappingAction] [prod-apm-elasticsearch103.example.com] failed to put mappings on indices

I see [o.e.c.s.MasterService] & [o.e.a.a.i.m.p.TransportPutMappingAction] show up in logs of Elasticsearch logs on posts on the internet, but I've yet to see a post that explains what the acronyms stand for.

So what does o.e.c.s. & o.e.a.a.i.m.p. mean / stand for?

OpenSearch/OpenDistro are AWS run products and differ from the original Elasticsearch and Kibana products that Elastic builds and maintains. You may need to contact them directly for further assistance. See What is OpenSearch and the OpenSearch Dashboard? | Elastic for more details.

Welcome!

That's the name of Java packages but only the first letter is displayed.

Thanks your comment does add clarity, still it'd be nice to know the full meaning if possible.

I think I figured it out based on your hint :slight_smile:

o.e.c.s.MasterService = org/elasticsearch/cluster/service/MasterService.java

Likewise
o.e.a.a.i.m.p.TransportPutMappingAction = org/elasticsearch/action/admin/indices/mapping/put/TransportPutMappingAction.java

Yes. But note that the code diverged A LOT with OpenSearch. We added so many features in the last years :smirking_face:

Did you look at Cloud by Elastic, also available if needed from AWS Marketplace, Azure Marketplace and Google Cloud Marketplace?

Cloud by elastic is one way to have access to all features, all managed by us. Think about what is there yet like Vector Search, Security, Monitoring, Reporting, ES|QL, Canvas, Maps UI, Alerting and built-in solutions named Observability, Security and what is coming next :slight_smile: ...
