  • An ROI tab is introduced to provide a concise overview of the benefits provided by the optimizer.
  • Added a few more charts on this dashboard.

Security & Certificate Management

Simplified Certificate Management

Pulse now centrally manages truststore certificates and passwords, eliminating the need to manually configure them in individual connector configuration files.

Previous Process

Users had to:

• Specify the truststore password in each connector configuration.
• Manually mount certificate files through connector volume configurations.
• Update connector-specific settings whenever certificates or passwords changed.

New Process

Users now:

• Provide the truststore path and password once through the Pulse CLI.
• Allow Pulse to securely store certificate details and encrypted passwords.
• Benefit from centralized certificate metadata management.
• Enable connectors to automatically retrieve certificate information and authenticate with target services.

Storage Locations

• Encrypted password: /data01/acceldata/config/security/certs_password
• Certificate metadata: Managed centrally by Pulse.

For details, see Manage SSL Certificates for Pulse Services and Connectors.

Reports

Generate Pulse Sanity Reports: Added support for generating Pulse sanity reports from the UI. The report runs a series of health checks across Pulse services, integrations, and infrastructure components, and generates an Excel report summarizing the results. Administrators can monitor report generation and manage reports from the Downloads > Reports page. For details, see Generate Service Status Report.

Monitoring and Integrations

Support for Standalone Kafka 3 with Kerberos and SSL/TLS: Pulse now supports monitoring Standalone Kafka 3 deployments running in KRaft mode secured with Kerberos authentication and SSL/TLS encryption. Supported capabilities include:

• Broker discovery
• Metrics collection
• Health monitoring
• Log monitoring
• Observability reporting

For configuration details, see Configure Pulse to Monitor Standalone Kafka 3 with Kerberos and SSL/TLS.

Deployment & Infrastructure

Introduced High Availability for the Pulse UI service (New UI): Pulse now introduces high availability for the UI service so that the service is always available. For details on the configuration, see Enable High Availability for the Pulse UI (New UI) Service.

Compatibility Updates

• Hook Version Update: Introduced Hook v2.1.2. This version is the recommended and fully compatible for Pulse 4.1.x, including 4.1.2. For details, see Supported Hook Versions.
• Pulse Hook JAR and Spark Connector Support: Pulse Hook JAR and Spark Connector now support Spark 3.5.8, enabling continued processing of Spark events and metrics for monitoring and observability integration.

Resolved Issues

• Resolved an issue where NiFi Flow File metrics were not displayed in Pulse UI for some clusters.
• Resolved the MongoBleed vulnerability issue by upgrading MongoDB to version 8.0.20 during the Pulse deployment.
• Resolved the Hive performance degradation issue caused by Tez hook failures (NATS client exceptions) when Pulse was down by removing the hook configurations.
• Resolved the Spark job failures caused by NATS server dependency when Pulse was down by updating the Spark hook to handle NATS connectivity failures gracefully.
• Pulse is now optimized to prevent the acceldatapulse user from consuming excessive CPU resources during monitoring and metadata collection activities.
• Fixed a dependency conflict in ad-dashplot-ui that caused the container to continuously restart during fresh Pulse deployments. The service now correctly handles HikariCP library dependencies, preventing startup failures caused by incompatible JAR versions.
