Are there any existing open source status boards out there that can do:
* http checks
* https cert checks
* ipv4 and ipv6 connectivity checks
* SMTP checks (also ipv4/v6)
..or at least enough of those features that adding a few more won't be that difficult?
I could just write my own I guess, but I have no much other stuff I need to write that I'd rather just contribute to an existing one.
