Sampling Override - Remove Blob Storage logs from all telemetryType(dependency, trace, exception)

[hjunior]

Is your feature request related to a problem? Please describe.
I would like to be able to use Sampling Override to filter out logs generated to AppInsight related to Blob Storage in all telemetryType (dependency, trace, exception)

Describe the solution you would like

{
"sampling": {
"percentage": 100,
"overrides": [
{
"telemetryType": "dependency",
"attributes": [
{ "key": "XXXXX", "value": "YYYYYY" } => ref to blob storage with error 409
],
"percentage": 0
},
{
"telemetryType": "trace",
"attributes": [
{ "key": "AAAAA", "value": "BBBBB" } => ref to blob storage with error 409
],
"percentage": 0
}
]
}
}

Describe alternatives you have considered

Additional context
I'm currently using version 3.7.2 of Agent, Linux Environment, Azure Functions, Java21 and Gradle.

@hjunior Have you taken a look at https://learn.microsoft.com/en-us/azure/azure-monitor/app/java-standalone-sampling-overrides#span-attributes-available-for-sampling?

[hjunior]

Yes. I've tried

http.response.status_code

But it didn't work

@hjunior

See the following note in https://learn.microsoft.com/en-us/azure/azure-monitor/app/java-standalone-sampling-overrides#span-attributes-available-for-sampling:

Only attributes set at the start of the span are available for sampling, so attributes such as http.response.status_code or request duration which are captured later on can be filtered through OpenTelemetry Java extensions. Here is a sample extension that filters spans based on request duration.

If you use the http.response.status_code attribute in the sampling override you should have an error message at the Application Insights start-up:

You can't use the "http.response.status_code" attribute for sampling overrides because you can only use the attributes set at the start of a span."
