[Nagiosplug-help] Cant monitor SSL Certs on vhosts with check_http

[Heinze, Markus]

No, one certificate for one host/ip.

The Apache doc says: (http://wiki.apache.org/httpd/NameBasedSSLVHosts)

As a rule, it is impossible to host more than one SSL virtual host on the same IP address and port.

But

In reality, Apache will allow you to configure name-based SSL virtual hosts, but it will always use the configuration from the first-listed virtual host (on the selected IP address and port) to setup the encryption layer.


Maybe you use SAN certificates (subject alternative names) or SNI (Server Name Indication), but I don't know if check_http support it.
So, I don't know your implementaion for multiple certificates.

@Heinze:

Do you have more than one certificate and virtualhost in the same host?
