- `disable_compat_1.9` ((#telemetry-disable_compat_1.9))
This allows users to disable metrics deprecated in 1.9 so they are no longer emitted, improving performance and reducing storage in large deployments. As of 1.12 this defaults to `true` and will be removed, along with 1.9 style http metrics in 1.13.
- `disable_hostname` ((#telemetry-disable_hostname))
