The path for disk space metrics is hardcoded as . but we allow the path for the disk space health indicator to be auto-configured. I think the path for the metrics should be equally configurable. I wonder if it might be possible to use the same property for both as I suspect it's unlikely that you'd want the two to be different.

When looking at this, we should keep the request to support multiple paths for the disk space health check in mind. I suspect that the requirement to have a health check for multiple paths would apply equally to metrics.
