no data for a UP target

[lcgogo]

Proposal

Use case. Why is this important?
I can see one target in prometheus target website, however, I can not get anything of it from prometheus database.

“Nice to have” is not a good use case. :)

Bug Report

What did you do?
I have config a target in the prometheus.yml and the target website is UP. However, in console, there is no target information. The other tragets are OK except that one

What did you expect to see?

What did you see instead? Under which circumstances?

It makes more sense to ask questions like this on the prometheus-users mailing list rather than in a GitHub issue. On the mailing list, more people are available to potentially respond to your question, and the whole community can benefit from the answers provided.

Maybe add the prometheus-users mailing list to README.md?
