What is the issue with the metric family?

• A.Unit is missing in the http_requests_total metric name.
• B.Metric names are missing a prefix to indicate which application is exposing the query.

• A.Use $value.instance instead of INSTANCE_NAME_HERE
• B.Use $expr.instance instead of INSTANCE_NAME_HERE
• C.Use $labels.instance instead of INSTANCE_NAME_HERE
• D.Use $metric.instance instead of INSTANCE_NAME_HERE

What is the best way to expose a timestamp from your application?
