Analytics: Roles & Permissions
Edited 73 days ago
Access to Fluent Analytics is controlled through a combination of permissions and role-based access control (RBAC). This document defines the permission model, role requirements, and configuration patterns for access to Fluent Analytics.Access to Fluent Analytics is controlled through a two-layer model: users must be assigned a role that 
  • has the `ANALYTICS_VIEW` permission AND 
  • is listed in the Analytics Query definition.
Analytics Query Settings
Edited 73 days ago
Analytics Queries are configured through settings that map query names to analytics resources in the Fluent Analytics backend services. Each setting follows the pattern `fc.analytics.queries.{domain}` and defines available queries, their resource locations, access permissions, and optional default parameters. Use this document to:
  • Understand query setting structure and naming conventions
  • Configure new analytics queries
  • Set default parameters for queries
  • Control query access through role-based permissions
Analytics Query Structure
Edited 73 days ago
This document defines the structure and syntax for querying the Fluent Analytics backend services. Analytics Queries reference pre-configured metrics by name (called "targets"), rather than defining individual fields like standard GraphQL queries. Targets provide controlled access to analytics metrics with built-in role-based permissions. Use this document to: 
  • Understand and construct analytics GraphQL queries 
  • Understand target name format and how it links to query settings
  • Configure filter parameters to refine query results 
  • Integrate analytics into dashboards and web applications
