The repository contains scripts and sources to generate Elasticsearch templates that comply with Common Data Model.
We are trying to solve the problem of conflicts and inconsistencies in log data as collected by, and from, different subsystems stored together as a unified data set under one warehouse.
Namespace hierarchy on the log metadata is the key concept. We use the Elasticsearch index templates and document mapping to cast the common metadata keys into usable documents.
Namespace corresponds to a top-level JSON key of Elasticsearch document. Namespace is usually defined per individual app or subsystem, so that different applications/subsystems not conflict in various metadata fields.
Create a namespace definition file in namespaces/ folder.
Create a sub-folder in templates/ folder, named as the desired template. (Alternatively copy/modify one of the existing template folders)
Add/modify template.yml definition file to include proper namespace
definitions. See for example templates/openshift/README.md
for the details.
