Reducing resources using exporter, unable to find inspiration from demo

[freshgeek]

Due to the excessive amount of information reported by the agent and the rising cost for cloud providers, I want to reduce costs by removing some invalid attributes and information, such as resources. However, according to the official documentation, the deletion of resources is done using an exporter, and I cannot find inspiration from the demo

io.opentelemetry.semconv.resource.attributes.ResourceAttributes#PROCESS_COMMAND_LINE
process.command_line

You can use configuration item -Dotel.experimental.resource.disabled-keys=process.command_line to disable the resource attribute process.command_line

Very perfectly solved my question, thank you very much. I have been looking at the zero configuration document, so I overlooked this document

cc @jack-berg @svrnm I think the proposed doc restructure will improve this?

@trask I would think so, yes!:-)
