🐞 Bug Fixes 🐞

• [Configuration] Append logic for merging JVM/OTLP configurations fix The CWA was unable to correctly append JVM/OTLP configurations when using the config (append) action. This change addresses this issue by allowing customers to append multiple configurations of this type. @lisguo https://github.com/aws/amazon-cloudwatch-agent/pull/1870

• [Configuration] Add support for EC2 metadata as dimensions Fixed an issue where the agent was unable to use the ${aws: formatting to substitute dimensions with EC2 metadata information or tags. @lisguo https://github.com/aws/amazon-cloudwatch-agent/pull/1876

• [Configuration] Add support for EC2 tags as dimensions for host metrics Fixed an issue where the agent only supports raw key/value pairs for the append_dimensions section of the host metrics config. This fix allows the agent to support dynamic AutoScalingGroup dimension using EC2 metadata. @lisguo https://github.com/aws/amazon-cloudwatch-agent/pull/1892

• [Logs] Memory leak fix when using publish_multi_logs flag This bug fix addressing a memory leak issue when using the publish_multi_logs flag with dynamically determined log destinations in CloudWatch Logs. This was due to the agent not correctly closing open goroutines for associated log files. @dricross https://github.com/aws/amazon-cloudwatch-agent/pull/1848

• [Contrib] Fixed messaging system logic Bug fix to facilitate the proper linking of cross service traces @sky333999 https://github.com/amazon-contributing/opentelemetry-collector-contrib/pull/368

• [Agent] Windows startup issue fix There was an error in the Agent where it would fail to start on windows on stderr. This change updates the agent control scripts to address the issue. @movence https://github.com/aws/amazon-cloudwatch-agent/pull/1906

💡 Enhancements 💡

• [Packaging] Updated OTeL JMX jar used by the agent The CWA was using a custom build of the OpenTelemetry JMX Metrics Gatherer JAR. There has been several newer versions released upstream that contain bug fixes for JMX metrics etc. This change removes the custom build in favor of using the upstream version. This also reduced the size of the agent by 200MB.

• [Agent] IPv6 Support on EC2 Adds CloudWatch Agent support for IPv6 on EC2 INSTANCES @Paramadon https://github.com/aws/amazon-cloudwatch-agent/pull/1871
