Chapter 1. Analytics 5.1.1

This release of Analytics applies to customers who use Resource Manager version 6.x with Analytics. Zenoss recommends that these customers upgrade to Analytics 5.1.1.

This release improves the ETL process, which extracts data from Resource Manager, transforms it for the Analytics database format, and then loads it into the Analytics database.

Resource Manager 6.x introduced a model indexing function that is based on Apache Solr. The new function enables Resource Manager to operate in significantly larger environments and improves overall performance. However, the ETL process consumed excessive memory in Analytics. This release of Analytics reduces the memory that is required during ETL processing.
