Data Stores

The Logging service provides an aggregation functionality through which DataGEMS service distributed logs are accumulated in a single centralized repository. These logs are persisted with various retention policies as needed.

Log Entry Datastore

The log entry data is stored in a NoSQL Elastic Search datastore. The indices define rollover policies that ensure that after a period of time the logs are discarded.

Updates

When updating the Elastic Stack service to newer versions, any needed indice updates are handled by the migration process of the ELK stack.
