Elastic APM 7.6.0 introduces significant enhancements, including support for messaging frameworks like Kafka and JMS, and the ability to act as a Jaeger intake, allowing seamless integration of Jaeger-instrumented traces into Elasticsearch without modifying existing code. The release also includes deployment annotations, providing automatic visualization of deployment impacts on application performance, and improved integration with the SIEM app to enhance security threat detection using APM data. Additionally, API key authentication is now available, offering more flexibility in managing services through multiple tokens and refined authorization rules. The update further enhances customization capabilities by supporting the configuration of APM indices from Kibana, facilitating a more tailored monitoring environment. Users can access Elastic APM 7.6.0 via the Elasticsearch Service on Elastic Cloud or download it as part of the Elastic Stack distribution.
