Metrics logging not working. Dart latest stable sdk

[Faisal Abid]

I've added some Metric logging to my Dart server app, hoping to see it in Observatory's metric page, but I can't seem to get them to appear.

Pseudo code of what I'm doing is below. Hope thats clear.

Any help would be appreciated!

server.dart

class .. {
 static Counter numAPI = new Counter("API Requests", "API Requests");


 static startServer(int port) async {
    Metrics.register(numAPI);


    //setup http
   // then on http request listener
    numAPI.value++
  }

}

I'm also curious, can I use the Service Protocol to query for this counter? Then I could wire it up to something like MRTG or RRDtool

Hi,

This works for me using the latest version of Dart:

import 'dart:developer';

main() {

  Counter numAPI = new Counter("API Requests", "API Requests");

  numAPI.value++;

  Metrics.register(numAPI);

Of course. Observatory uses only the service protocol to gather data.
