Z APM Connect Distributed Gateway

Z APM Connect Distributed Gateway (Z APM Connect DG) is a required processing component to trace calls from services on z/OS. This component acts as a bridge between the Z APM Connect tracing components and the Instana backend. Its primary function is to receive trace data from different Z APM Connect tracing components, ensure the data is correctly formatted, and then send it to the Instana backend. The Z APM Connect DG component must be installed on a distributed system with connectivity to your monitored z/OS® systems and APM vendors.

The Z APM Connect Distributed Gateway operates in the following way: Firstly, it receives trace data from different Z APM Connect tracing components, and stitches the asynchronous events from z/OS systems to construct a complete transaction. Secondly, it converts the transaction data from the host system into a format that can be understood by APM vendors, specifically the Instana backend. Then, it sends the transaction data to the Instana backend. In the following example, the implementation uses a simple CICS workload.
