Description
What are you trying to achieve?
System.Diagnostics.DiagnosticSource v8.0 introduced the ability to instantiate an insrument with tags. for example Counter with tags.
Using System.Diagnostics.DiagnosticSource v8.0, when creating and exporting a counter with tags, I expect tags declared in an instrument will be attached and be exported (in prometheus).
Example Code:
Meter meter = new Meter("MyMeter", "1.0");
TagList counterTags = new TagList() {
{"counter_tag", true}
};
Counter<long> myCounter = meter.CreateCounter<long>("myCounter", null, null, counterTags);
MeterProvider meterProvider = Sdk.CreateMeterProviderBuilder()
.AddMeter("MyMeter")
.AddConsoleExporter()
.AddPrometheusHttpListener(options => options.UriPrefixes = new []{"http://localhost:9000"})
.Build();
myCounter.Add(1);
meterProvider.Dispose();What did you expect to see?
I expect tags declared in an instrument will be attached and be exported (in prometheus).
Actual output, without the instrument tags
# TYPE myCounter_total counter
myCounter_total 1 1706978095318
# EOF
