SmartAgent Version 9.12.6

Release Date: April 3, 2026

Version Overview

SmartAgent 9.12.6 adds Cloud Foundry Garden container application monitoring on Linux, integrates JavaAgent 9.12.4, GoAgent 5.0.2, and NginxAgent 3.8.5 fixes and improvements, and refines platform-initiated reset behavior so update records are preserved, reducing false update-record alerts.

• ✨ Cloud Foundry Garden: Linux packages support monitoring Garden container applications

• ✨ JavaAgent 9.12.4: Improved exception blacklist filtering; fixed connection pool metrics when c3p0 getDataSourceName is null; fixed NPE in Spring Cloud Gateway scenarios

• ✨ GoAgent 5.0.2: Fixed uncaught exceptions when gRPC status.message exceeds 100,000 characters

• ✨ NginxAgent 3.8.5: Fixed incorrect string length calculation causing excessive memory use

• 🔧 Platform behavior: Platform-initiated reset no longer clears update records, reducing false positives

Upgrade Recommendation

• Linux users are recommended to upgrade for Garden monitoring and agent stability fixes;
• Environments using Java connection pools (including c3p0), Spring Cloud Gateway, gRPC, or the Nginx agent should prioritize upgrading.

New Features

1. Support monitoring Cloud Foundry Garden container applications.

Feature Optimizations and Fixes

1. JavaAgent Upgraded to 9.12.4

Feature Optimizations

• Optimized exception blacklist filtering for exceptions not associated with a span.

Bug Fixes

• Fixed database connection pool collection: in rare cases c3p0 getDataSourceName was null, preventing connection pool metrics from being reported (affects: JavaAgent 8.0.0～9.12.2, SmartAgent 6.0.0～9.12.3).
• Fixed null pointer exception (NPE) in Spring Cloud Gateway scenarios (affects: JavaAgent 9.11.0～9.12.3, SmartAgent 9.11.0～9.12.4).

2. GoAgent Upgraded to 5.0.2

Bug Fixes

• Fixed mishandling of gRPC status.message longer than 100,000 characters that could throw uncaught exceptions (affects: all versions, SmartAgent prior to 9.12.4).

3. NginxAgent Upgraded to 3.8.5

Bug Fixes

• Fixed incorrect len calculation for strings causing excessive memory use (affects: NginxAgent 3.3.0～3.8.4, SmartAgent 8.3.0～9.12.4).

4. Platform Reset and Update Records

• On platform-initiated reset, update records are not cleared, avoiding false update-record alerts.
