Description

With OpenTelemetry support added to cppTango and PyTango since version 10.0.0, we tried it out operationally at MAX IV. We provide some examples of the traces, trends, and other data available when running at scale. We report on the compute and performance impact for clients and servers, as well as practical issues. For the backend servers that receive and query all the telemetry data (Grafana Tempo for traces and Grafana Loki for logs) we also look at the compute resources required.
