Help to ignore InProc sampling dependencies about applicationinsights-java

[gleidson]

Hey @heyams, thanks for your quick response.

I'm using the version 3.4.18.

With the HTTP dependency, I was able to use sampling overrides to ignore some requests.

I will set the self-diagnostics level to debug as suggested to get the attributes.

@heyams, it works!

Thank you!

{
  "preview": {
    "captureControllerSpans": false
  }
}

since version 3.2.0, we don't collect controller "InProc" dependencies by default. Which version of Java agent are you using?
If those are not controller InProc dependencies, you can certainly use sampling overrides like this:

{
  "connectionString": "...",
  "preview": {
    "sampling": {
      "overrides": [
        {
          "telemetryType": "dependency",
          "attributes": [
            {
              "key": "<attributre_key>", // replace it with an actual attribute key
              "value": "<attribute_value>", // repleace it with an actual attribute value
              "matchType": "strict" //or "regexp"
            }
          ]
          "percentage": 0
        }
      ]
    }
  }
}

@gleidson please let me know if you have further questions.

Hey @heyams, I tried the configuration below

        {
          "telemetryType": "dependency",
          "attributes": [
            {
              "key": "thread.name",
              "value": "boundedElastic*",
              "matchType": "regexp"
            }
          ],
          "percentage": 0
        }

For the "exporting span" below:

2024-01-19 17:49:02.883-03:00 DEBUG c.m.a.a.i.exporter.AgentSpanExporter - exporting span: SpanData{spanContext=ImmutableSpanContext{traceId=4def5e93043cea4c5fa41f757a081c7f, spanId=9bc7fea1441e1d9e, traceFlags=01, traceState=ArrayBasedTraceState{entries=[]}, remote=false, valid=true}, parentSpanContext=ImmutableSpanContext{traceId=00000000000000000000000000000000, spanId=0000000000000000, traceFlags=00, traceState=ArrayBasedTraceState{entries=[]}, remote=false, valid=false}, resource=Resource{schemaUrl=https://opentelemetry.io/schemas/1.21.0, attributes={service.name="my-service", telemetry.sdk.language="java", telemetry.sdk.name="opentelemetry", telemetry.sdk.version="1.31.0"}}, instrumentationScopeInfo=InstrumentationScopeInfo{name=azure-storage-blob, version=12.24.1, schemaUrl=https://opentelemetry.io/schemas/1.17.0, attributes={}}, name=AzureBlobStorageBlob.setMetadata, kind=INTERNAL, startEpochNanos=1705697342693931300, endEpochNanos=1705697342843649200, attributes=AttributesMap{data={applicationinsights.internal.item_count=1, thread.name=boundedElastic-6, thread.id=193, az.namespace=Microsoft.Storage}, capacity=128, totalAddedValues=4}, totalAttributeCount=4, events=[], totalRecordedEvents=0, links=[], totalRecordedLinks=0, status=ImmutableStatusData{statusCode=UNSET, description=}, hasEnded=true}

But it didn't work as expected. Can you help me with an example to ignore the span above?

@gleidson

please try this instead:

        {
          "telemetryType": "dependency",
          "attributes": [
            {
              "key": "thread.name",
              "value": "boundedElastic.*", // use '.*'
              "matchType": "regexp"
            }
          ],
          "percentage": 0
        }
