Icinga2 HTTPS and ssl key expiration check

Create a host file in /etc/icinga2/conf.d/hosts eg website-ripe.conf

Create the host details
object Host "website-ripe" {
  import "generic-host"
  address = "ripe.net"
  address6 = "::1"
  vars.os = "Linux"
  vars.sla = "24x7"
}


How to monitor a website over SSL (service)
object Service "httpS" {
  host_name = "website-ripe"
  vars.http_vhost = "ripe.net"
  vars.http_address = "193.0.6.139"
  vars.http_ssl = "1"
  vars.http_sni = "1"
  vars.http_warn_time = "5"
  vars.http_critical_time = "10"
  check_command = "http"
}

Monitoring the SSL key expiration date, give warning 30 before and alert at 14 days before. (service)
object Service "website-ripe-key-expire"{
  host_name = "website-ripe"
  check_command = "check-ssl-exp"
  vars.days = 30,14
  vars.url = "ripe.net"
}
Because it's not a default check -the -C (certificate) parameter is not available in Icinga- we need to create a custom checkCommand
object CheckCommand "check-ssl-exp" {
import "plugin-check-command"
command = PluginDir + "/check_http -H $url$ -C$daysquot;
}



Error:
[2014-07-30 12:58:00 +0200] critical/config:
Config error: Invalid value for attribute: Object 'check_ssl' (Type: 'CheckCommand') at /etc/icinga2/conf.d/hosts/website-ripe.conf:28 -> Attribute 'methods'
[2014-07-30 12:58:00 +0200] critical/config: 1 errors, 0 warnings.

Solution:
add   import "plugin-check-command" ot the oject checkcommand section.
