[SR-Users] xhttp_prom Metric Naming Issue

[Daniel-Constantin Mierla]

Hello,

I am not familiar with prometheus, but you can create an issue on the
tracker at github.com/kamailio/kamailio and we can assign it to the the
developer of the module. You can also make a pull request with a fix
that can be reviewed and merged.

Cheers,
Daniel
