I'm using the OpenTelemetry Java agent and want to remove resource information when collecting logs.

[JangCool]

I'm receiving log information using the Java collector server version, but I do not want to receive resource information.

Even if I pass resource-related settings as empty values, they are still sent. Are they being sent as default values? Is there a way to exclude them? It seems to unnecessarily consume data for transmission. The same goes for trace and metrics information. Please help.

Resource information is sent once per exported batch so when your exported batch has 100 spans there will be only a singe copy of the resource attributes.

otel.java.disabled.resource.providers=

you will need to list the class names of the providers you wish to disable. Most of the providers can be found in https://github.com/open-telemetry/opentelemetry-java-instrumentation/tree/main/instrumentation/resources/library

Even though I have added all the resources to the list as shown below, the issue still persists. How can I remove properties that start with the [telemetry.]? And is service.instance a default value?

otel.java.disabled.resource.providers=io.opentelemetry.instrumentation.resources.ContainerResourceProvider,io.opentelemetry.instrumentation.resources.HostResourceProvider,io.opentelemetry.instrumentation.resources.OsResourceProvider,io.opentelemetry.instrumentation.resources.ProcessResourceProvider,io.opentelemetry.instrumentation.resources.ProcessRuntimeResourceProvider,io.opentelemetry.instrumentation.resources.ManifestResourceProvider,io.opentelemetry.instrumentation.resources.HostIdResourceProvider,io.opentelemetry.instrumentation.resources.HostIdResourceProvider,io.opentelemetry.instrumentation.resources.AttributeResourceProvider

The attributes starting with telemetry are required by otel specification https://opentelemetry.io/docs/specs/semconv/resource/#telemetry-sdk As far as I know opentelemetry java sdk does not offer a configuration option for disabling these. If you need to remove this I'd try implementing an agent extension Have a look at https://github.com/signalfx/splunk-otel-java/blob/main/custom/src/main/java/com/splunk/opentelemetry/TruncateCommandLineWhenMetricsEnabled.java for ideas, if you wish to drop all resource attributes you could return Resource.empty() from the customizer.
service.instance.id is provided by https://github.com/open-telemetry/opentelemetry-java/blob/main/sdk-extensions/incubator/src/main/java/io/opentelemetry/sdk/extension/incubator/resources/ServiceInstanceIdResourceProvider.java

[JangCool]

I understand. Thank you for the answer.

I have a similar need. What did you end up doing?

I tried to set:

OTEL_JAVA_ENABLED_RESOURCE_PROVIDERS=io.opentelemetry.sdk.autoconfigure.EnvironmentResourceProvider

But the result is that it completely stops traces from being transmitted...

So now I just remove the keys I'm less interested in with OTEL_RESOURCE_DISABLED_KEYS but it would be better if I could disable resource collection altogether (except the mandatory part).
