I find the standard blackbox_exporter far too limiting and static so I wrote an exporter which queries DNS zones from the Google API and creates targets dynamically from that.
It also has a feature which will query internal databases to find expected targets (kinda like service discovery). This covers more specific checks than what the DNS-based targets will provide.
These together mean that essentially no endpoint in our infrastructure is missing from being monitored in some fashion.
The exporter performs SSL checks (lifetime remaining etc) as well as providing HTTP/TCP latency metrics.
