Can metric names contain numbers and special characters? What about spaces?
I recommend metric names be restricted to regular ascii characters and numbers with no spaces.
I don’t believe there are any specific limitations
You cannot use - in simple metric names & compound metric ids, nor can you use spaces in compound metric ids & simple metric names.
Recommendation is to:
- Always start with a capital letter
- Every next logical word should have a capital letter without a space
Also, the length of the compound metric id will be limited by what is allowed by relational database id column
