Description

This PR adds attributes sent from the JS SDK describing device memory and cpu core count properties. As we discussed in Slack, we want to take the opportunity to move the non-existing/suboptimal attribute names over to properly name-spaced attribute names.

Old attribute (deprecated) New attribute OTel equivalent
hardwareConcurrency device.cpu.logical_core_count device. exists but not the exact attribute
deviceMemory device.memory.estimated_capacity device. exists but not the exact attribute

I checked and none of these attributes are used in dashboard prebuilt configs.

Worth noting:

  • I went with device.memory.estimated_capacity because browsers really only give a rough "bucket" how much memory is available. They cap it at 8GB mostly. Also changed the expected type to integer since IMHO it makes more sense to query/aggregate on them. We can send gigabyte as the unit on the attribute.
  • The browser likely only returns a smaller than actually existing number of CPU cores (navigator.hardwareConcurrency). This is because browsers report what amount of logical cores they have at their disposal.

PR Checklist

  • I have run yarn test and verified that the tests pass.
  • I have run yarn generate && yarn format to generate and format code and docs.

If an attribute was added:

  • The attribute is in a namespace (e.g. nextjs.function_id, not function_id)
  • I have used the correct value for pii (i.e. maybe or true. Use false only for values that should never be scrubbed such as IDs)

If an attribute was deprecated:
