Document/Sample project for new 3.x applications

[deman-Innotractor]

Is your feature request related to a problem? Please describe. When creating a new application I notice that there are a lot of configurations needed for the following elements:

• Span creation
• Structured logging
• Configuration of Logback/other logging

Describe the solution you would like I would like to see in the wiki or a somewhere in the code a sample application that I could follow and run to see it in action.

Describe alternatives you have considered Wiki/Sample project

Additional context Currently I'm working for an application and notice that the documentation is not filling my needs. A startup/guide and/of sample project would greatly help.

hi @deman-Innotractor! the reason we don't provide a specific sample application, is that the javaagent will work with any sample application.

do you have a specific issue you are having, maybe we can help you with that?

Hi @trask, sorry for the mess of text below. Currently we have accepted the current situation but if we can improve on this, that will be great. If needed I could try and make some examples projects for the points.

At the time I needed it to combine the right OperationId (that another application generated) and noticed that it only accepted a shorter version.

An other problem was that structured logging was (and still is) not working for me. I'm not sure if the problem is a Azure "Application Insights" problem, or that it was somewhere else. I was thinking it was dependent on some structural logging framework, and decided then that it took too much time to get it working and dropped it then.

In that time I was also struggling to get it all working as needed. The points that I was confused was:

• Is there a mode that I can log to a local logging sink, and how so.
• Can I resume a OperationID if I set this? And how does it work.
• Is structured logging supported at all? Or just to Azure DevOps not?
• How can I make my custom "Autocollected dependencies".
• How can I make use of the "metrics" call public final Flux<T> metrics()
• How can I use 'GlobalOpenTelemetry' in combination with Azure.

Below this is some sample (c# vs java logging) differences (using java:3.3.1): Java id: b7f741da59477e80 C# id: 34b999035fed46388a25cade91dc3d51

Java operation_Id: f76809c8ed1581827a2848fcca879ca2 C# operation_Id: 23352843fc222d48871282685216fd1e

Java operation_ParentId: f76809c8ed1581827a2848fcca879ca2 C# operation_ParentId: fabf3312ab26d744

Below is some code that I tried to make some of those questions work. Note: this was just to get some tests in.

        var tr = GlobalOpenTelemetry.get().getTracer("tracer");

        var span = tr.spanBuilder("spanBuilder")
                .setSpanKind(SpanKind.CLIENT)
                //.setParent(Context.current().with(Span.current()))
                .startSpan();

        span.end();

        var id = "eeeedddddddddddd";

        var traceID = "0000000000000000" + id; //TraceId.fromLongs(0, 13); //Operation_Id
        var res = TraceId.isValid(traceID);
        var spanId = id; //parent-id


        var parent = SpanContext.create(traceID, spanId, TraceFlags.getSampled(), TraceState.getDefault());

        if (!parent.isValid()){
            return;
        }

        var context = Context.current().with(Span.wrap(parent));

        var span = tr.spanBuilder("invalid spanId")
                .setParent(context)
                .startSpan();

        try(Scope scope = span.makeCurrent()) {
            Span childSpan = tr.spanBuilder("child").startSpan();

            childSpan.recordException(new IllegalArgumentException("Test"));

            childSpan.end();

        } finally {
            span.end();
        }

        int i = 0;
        while (true){
            if (i++ > 10000){
                return;
            }
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }

hi @deman-Innotractor!

• Is there a mode that I can log to a local logging sink, and how so.

I didn't follow this, can you explain a bit more?

• Can I resume a OperationID if I set this? And how does it work.

I added an example for this in our new Samples repo: https://github.com/Azure-Samples/ApplicationInsights-Java-Samples/tree/main/advanced/manual-trace-propagation

• Is structured logging supported at all? Or just to Azure DevOps not?

I updated the docs to explicitly mention structured logging: https://learn.microsoft.com/en-us/azure/azure-monitor/app/java-in-process-agent#send-custom-traces-and-exceptions-by-using-your-favorite-logging-framework:~:text=configuration%20options.-,Structured%20logging,-(attaching%20custom%20dimensions

• How can I make my custom "Autocollected dependencies".

Can you explain this a bit more also?

• How can I make use of the "metrics" call public final Flux<T> metrics()

Can you explain this a bit more too? i'm not sure what this metrics() method refers to

• How can I use 'GlobalOpenTelemetry' in combination with Azure.

I updated the docs to add this: https://learn.microsoft.com/en-us/azure/azure-monitor/app/java-in-process-agent#add-spans-using-the-opentelemetry-api
