Detailed Description

A numeric ID is a numeric value that is used as an identifier, and not as a measurement value. Examples are message numbers and error codes.

Numeric IDs are classified as non-calculable because it doesn’t make sense to perform arithmetic with them. For example, the mean of the last seven message numbers would hardly ever provide useful information. By using a data type of numeric ID instead of a gauge or counter, the application indicates that arithmetic with the numbers is probably nonsensical. An agent could create statistical summaries based on these values, such as generating a frequency histogram by part number or error number.

ARM supports two numeric ID types:

• 32-bit integer: ArmMetricNumericId32
• 64-bit integer: ArmMetricNumericId64
