Improve prometheus port and services documentation

XMLWordPrintable

    • Tracing Sprint # 260

      Related to case 03902846, customer has reported that it's not clear how to use ports when following the Configuration of the monitor tab in Jaeger UI section. 

      It is raised that:

      I cannot find any explanation on the port used for the prometheus exporter. It is set to 8889 on the documentation, but if I check the service list, the otel collector monitoring service is using port 8888. Where is this port 8889 configured?

       

      In general, we will benefit from adding:

      • A general description of what services are used and configured in the OpenTelemetry configuration
      • An explanation of the fact that, by default, the 8888 port is used for self monitoring, and how that one is exposed when enabling self observability. This must include changes in the "Configure metrics for the monitoring stack" section, and
        • Clearly explain why we mention there 2 different ports: 8888 and 8889
        • What is the function of each of them
        • Is any service created to expose these ports? Which one? 
      • A Note and a link to this port explanation in the monitoring tab section
