WSO2 API Manager Integration with Prometheus and Grafana

Question

I'm trying to integrate Prometheus and Grafana with the latest version of WSO2 API Manager (4.2.0) and I'm following the below mentioned documentation.

https://apim.docs.wso2.com/en/latest/observe/streaming-integrator/setting-up-si-statistics-dashboards/

However, the documentation describes the integration of Prometheus and Grafana with the WSO2 Streaming Integrator. I was unable to find a proper documentation which describes the integration with the WSO2 API Manager.

Please correct me if I'm wrong, but I believe that the documentation should be describing the integration with WSO2 API Manager and not the WSO2 Streaming Integrator.
