scrape interval option would be useful

along with scrape timeout, scrape interval would be nice if you want to probe specific metrics endpoints, like script exporters and so on

Hi, If I remember correctly the targets are just loaded each time the exporter's metrics page is loaded (i.e. it acts like kind of like a reverse proxy). So there isn't really a concept of a re-scaping interval.

Hi @warmans thanks for the replay and the clarification.. I just had a use case where this could be useful. in some case exporters(in my case script exporter) are also working with /probe to execute something and return metrics back.. so in this case scraping interval would really nice to have

I'm not sure I understand. Do you mean something like a rate limiter to stop it calling targets too often? the problem is currently it doesn't store any data. It just goes through each target and then merges all the results into a single metrics page.

The code is quite simple - I'd be happy to look over a MR if you could submit one.
