Datadog trace ID support for OpenTelemetry
IronTap can be configured to convert OpenTelemetry trace IDs to the 64 bit Datadog trace ID format. This ensures that trace IDs we provide in tags to Datadog users can be searched for in the Datadog UI.
In some use cases, like Db2 Deadlocks, z/IRIS highlights a temporary relationship between two otherwise independent and unrelated services. We do this by cross-referencing the trace IDs using tags. Staying with the Db2 deadlock example, z/IRIS enriches one of the deadlocked call traces with a Deadlock Participant span, which contains the trace ID of the other request that was impacted by the same deadlock. The other call trace will also get an additional Db2 Deadlock span, which contains information about the deadlock, the relevant database resource and more information about affected requests.
