Hi,
It now seems to have been removed from the internet, lol.
Its here https://github.com/oetiker/SmokePing
Thanks very much. I meant to mention that echoping and echoping-dns are no longer available, which are critical to the operation of smokeping.
I also recall having a problem with EchoPingHttps and using it with CDNs like Cloudflare with multiple domains on a single cert.
I'll check out prometheus, thanks.
Alex
