SmartGate Version 3.5.0

Release Date: September 30, 2025

Version Overview

SmartGate 3.5.0 focuses on enhancing plugin runtime mode flexibility and fine-grained control of failed cache reporting strategies, and completes the upgrade of Monitoring Point (STM) plugin to version 1.4.7.0.

• ✨ Core Capability Enhancements:

  • Plugins support single-instance / multi-instance mode;
  • Plugins support injecting log level through environment variables for debugging and operations;
  • Failed cache reporting strategy optimization: Intelligently retries only after network recovery (default maximum 10 times), avoiding invalid accumulation and ensuring efficient cache file cleanup;
  • STM 1.4.7.0: Compatible with historical version upgrades to SmartGate 3.5.0.

• ⚠️ Important Limitations:

  • APM < V2.6.0: No batch forwarding, data sent directly without cache;
  • APM < V2.10.0: K8s YAML display anomalies;
  • APM < V3.5.0: K8s YAML incompatible with SmartGate 3.3.0.

::: tip Upgrade Recommendation

• It is recommended that all users upgrade the APM platform to V3.5.0 or higher for complete functionality;
• If you need to use multi-instance deployment or rely on reliable offline cache reporting mechanism, please upgrade to the current version.

Linux x86_64 System

Supported Platform Versions

• One Platform: V2.4.0 and above

Limitations

1. APM version < V2.6.0: Agents do not support batch forwarding, data will be forwarded directly, no local cache mechanism;
2. APM version < V2.10.0: YAML files of K8s resource objects display abnormally on the platform;
3. APM version < V3.5.0: K8s resource object YAML files are incompatible with SmartGate 3.3.0.

Integrated Plugin Versions

• Monitoring Point version: 1.4.7.0

Feature Optimizations

1. Plugin Runtime Mode Enhancement:

   • Supports single-instance / multi-instance mode;
   • Supports passing log level to plugins through environment variables;

2. Failed Cache Reporting Strategy Optimization:

   • When config request returns non-2xx status code or Protocol Buffer parsing fails, it is determined as "disconnected state", does not trigger cache reporting;

     • After network recovery, defaults to retry up to 10 times (configurable) to report failed message blocks;

     • If retry fails, skip that message block; when all cache file content has been successfully reported or skipped, automatically delete the cache file;

3. Monitoring Point (STM) Upgraded to 1.4.7.0

   Changes:

   • 【New Feature】 Compatible with smooth upgrade from historical versions to SmartGate 3.5.0.
