 The majority of OPEA's micro and mega services are equipped to support OpenTelemetry metrics, which are exported in Prometheus format via the /metrics endpoint.  
 For further guidance, please refer to the section on `Telemetry Metrics <https://github.com/opea-project/GenAIComps/tree/main/comps/cores/telemetry#metrics>`_.
 Prometheus plays a crucial role in collecting metrics from OPEA service endpoints, while Grafana leverages Prometheus as a data source to visualize these metrics on pre-configured dashboards.

 Code Instrumentations for OPEA Tracing
 ****************************************
 
 Enabling OPEA OpenTelemetry tracing for a function is straightforward. 
 First, import opea_telemetry, and then apply the Python decorator @opea_telemetry to the function you wish to trace. 
 Below is an example of how to trace your_func using OPEA tracing:
