Version 2021
Statistics Repository
PostgreSQL is not supported as Statistics repository.
The Statistics and Enterprise Manager repository should reside in a database that is separate from your production databases. You can create the Statistics and Enterprise Manager repository using the MicroStrategy Configuration wizard.
The statistics repository contains data on the MicroStrategy system's usage and performance; the staging tables are populated by all projects that are configured to log statistics.
See Intelligence Server Statistics Data Dictionary for an explanation of the collected statistics and details about the contents of the statistics tables.
