Release 9.0.18.1¶

New API Endpoint for Ranger Database Metrics¶

A dedicated API endpoint, /service/metrics/db, has been introduced to expose only database-related metrics. This helps avoid duplication in metric ingestion in environments with multi-pod deployments, and improves metrics efficiency.

The existing /service/metrics/prometheus endpoint is still available for service-wide metrics. Metric collection has also been optimized to reduce redundant data processing and enhance performance.

Enhanced Health Monitoring with Prometheus and Grafana¶

Health monitoring for the Portal has been improved through the integration of Prometheus metrics and Grafana dashboards. The update adds detailed error tracking, performance insights, and failure analysis These metrics enable real-time monitoring, simplify root cause analysis, and help identify performance issues and system failures more efficiently.

Fixed Redundant Task already exists log entry in Ops Server¶

The Ops Server previously logged multiple instances of the Task already exists message for the same event. This has been streamlined to avoid redundant entries and enhance log readability.

Enabled Fallback to DBX Login User When JWT Token is Missing in DBX-FGAC¶

When a JWT token is not available and fallback is enabled, the plugin now properly switches to DBX login user authentication as expected. This prevents authentication failures caused by missing JWT tokens. This update handles JwtTokenException properly, avoiding unnecessary authentication errors.

Resolved Spark Version Retrieval Issue on EMR 7.x Core Nodes Affecting SQL Queries¶

The plugin is now able to fetch Spark version details in EMR 7.x core node environments. This change resolves query execution failures caused by missing version data, improving reliability on newer EMR setups.

Improved Test Result Visibility and Navigation¶

• We've enhanced the "Run Tests" page in Privacera Diagnostics to provide more immediate insight into test execution. Key improvements include:
• Last Test Status and Time: Each pod now displays the status and timestamp of its most recent execution.
• Direct Link: A hyperlink has been added that directly navigates to the pod page associated with each test, facilitating quick access to detailed test results and logs for analysis.

Improved Connector Log Testing for Enhanced Reliability¶

This release introduces comprehensive testing for connector logs, ensuring robust and predictable behavior. Key improvements include:

Reliable Log File Management:

• Implemented size checks for rolling appenders, guaranteeing that log files adhere to configured size limits.
• Validated backup file naming conventions using regular expressions, ensuring consistent and predictable file organization.
• Verified the correct number of backup files, preventing excessive disk usage and maintaining efficient log rotation.

Enhanced Diagnostics Logging: Size-Based Log Rotation¶

Implemented size-based log rotation for both the diagnostics server and client. This ensures predictable log file sizes and prevents excessive disk usage, improving system stability and maintainability.
