Search before asking

• I had searched in the issues and found no similar feature requirement.

Description

Inconsistent naming will cause portability and compatibility issues, as well as, make users confused when the number of metrics gets large. Therefore, we need to:

• Establish the naming convention for DS metrics.
• Change the current metrics names following the convention.

We could refer to official docs micrometers metrics naming convention for details.

• One possible approach and example could be found here in naming convention section.
