Irontap uses an internal telemetry format to create traces. Instana specific trace semantics and tags are applied when z/IRIS is configured to integrate with Instana APM.
Below is a description of Instana specific trace semantics and tags for z/OS Connect traces. Unless otherwise specified below, please refer to z/OS Connect Spans for a complete list of tags available for Instana users.
