Health Signatures

Each sensor has a curated knowledgebase of health signatures that are evaluated continuously against the incoming metrics and are used to raise issues or incidents based on user impact.

Built-in events trigger issues or incidents based on failing health signatures on entities, and custom events trigger issues or incidents based on the thresholds of an individual metric of any given entity.

For more information about built-events for the Glassfish sensor, see the Built-in events reference.


Instana provides tracing support for Glassfish. For more information, see Monitoring Java virtual machine (JVM).
