This session will demonstrate how to collect signals from GraalVM Native Image applications with OpenTelemetry in a "no collector" approach, providing valuable insights for those seeking to optimise their data collection processes. Furthermore, I will share insights and benefits on the technical aspects, based on my experience of supporting several customers in real-world scenarios.
GraalVM Native Image is an excellent technology for reducing the time taken to start up, the potential for attack and the amount of memory required by Java applications, offering significant benefits to customers. From an observability standpoint, however, the typical monitoring agent is not the optimal choice for native image applications, as they do not require a standard JVM to run.
To address this challenge, the "no collector" approach is emerging as the preferred solution for Java-based microservices, including GraalVM Native Image. This approach is gradually being supported by various observability solutions and development frameworks.
Attendees will gain the knowledge to effectively use the no-collector approach for monitoring GraalVM Native Image applications.
