Tencent Cloud OpenTelemetry Java Agent Enhanced Edition

Tencent Cloud OpenTelemetry Java Agent Enhanced Edition is based on the openTelemetry-java-instrumentation from the open-source community and developed further under Apache License 2.0. It includes a reference to the OpenTelemetry License within the agent packet. Building on the open-source agent, the Tencent Cloud OpenTelemetry Java Agent Enhanced Edition has made significant improvements in areas such as Event Tracking density, advanced diagnosis, performance protection, and enterprise-level capabilities. In addition, the Tencent Cloud OpenTelemetry Java Agent Enhanced Edition also adheres to the OpenTelemetry protocol standards. When the automatic Event Tracking does not meet user scenarios, you can see OpenTelemetry official documentation for customizing business Event Tracking.

Agent Support Cycle

To continuously enhance the product capabilities and stability of Tencent Cloud OpenTelemetry Java Agent Enhanced Edition, support new versions of open-source components, and promptly fix agent defects and security vulnerabilities, APM will continuously iterate the agent, regularly releasing new versions. It is recommended to follow the release cadence and update the agent version timely.
Each officially released Tencent Cloud OpenTelemetry Java Agent Enhanced Edition, from the release date, has a fixed support period of 6 months. Starting from the 4th month, APM will notify you in the console that the agent is nearing expiration. From the 6th month, APM will notify you in the console that the agent has expired. After the agent expires, it will not affect the use of APM; if you need technical support for the agent, it is recommended to upgrade the agent version first. For upgrading, see Upgrading Agent Version.

Other Agents

Besides Tencent Cloud OpenTelemetry Java Agent Enhanced Edition, other agents are provided by the open-source community, including the OpenTelemetry community, and Skywalking community. See the connect guide for agent installation.
For applications deployed on TKE, the Tencent Cloud Observability team provides an Operator scheme: tencent-opentelemetry-operator. Built upon the community opentelemetry-operator, it enables agent auto-injection, facilitating applications to connect APM quickly. Currently, tencent-opentelemetry-operator supports the following agent versions:
