The line I refer to replaces any non-alphanumeric character with an underscore, not only slash though. In this case, the string refers to a node name that contains an interface name. I also use the exporter v2 and didn't see this issue with slash before, so rolling this out effectively renames metrics which makes their history a bit less useful after deployment. Added a screenshot to the issue to demo the effect of removing only the token's sanitization.

I logged the issue in GitHub but please let me share it here to understand the intent so I can propose a change that fits the release window if warranted. https://github.com/FDio/vpp/issues/3686 Best, Carlos
