"tcps" type check
Currently we have HTTP, HTTPS, ICMP, and TCP type checks. These cover probably most things, with TCP being the escape valve for non-HTTP based services. However, I have some non-HTTP services that are nevertheless behind TLS, for example LDAPS. It would be good to have these checked not only as TCP but as TCP+TLS, with the same certificate verification logic that goes into HTTPS. That is, this would be to TCP as HTTPS is to HTTP.
Thanks for suggestion, so basically we would be talking about a TCP + TLS handshake test, the connection would then be closed before exchanging any data. Something like "echo | openssl s_client -connect updown.io:443" ? does this work well with your LDAPS?
