No, because:
1. blackbox_exporter only supports a single target per scrape
2. In prometheus relabelling, a single target can only result in a single
scrape (or no scrapes, if you drop the target). You cannot expand a single
target to multiple targets.
If the set of ports is fixed, then you can have separate prometheus scrape
jobs for each port:
- one for port 80
- one for port 443
- etc as required
and in those scrape jobs, you can use 'drop' actions to drop the target if
the given port is not contained with the port list.
Otherwise, you need to move all your target collection logic outside of
prometheus, and get prometheus to read it (e.g. using file_sd_configs or
http_sd_configs)
