Plugin found working properly

This is the most advanced & simple script to achieve the Nagios SSL Expiry Monitoring. Worked Well. Some Nagios Administrators, here is my configuration file. ========================== commands.cfg { define command command_name check_ssl_cert_expiry command_line $USER1$/check_ssl_cert_expiry -h $ARG1$ -w $ARG2$ -c $ARG3$ } ========================== { define service use generic-service check_interval 60 retry_interval 5 host_name central_nagios service_description Server SSL Certificate Expiry of YOUR DOMAIN NAME check_command check_ssl_cert_expiry!YOUR_DOMAIN_NAME!60!30 contacts nishithvyas notification_interval 60 notifications_enabled 1 } Done.


It's works, but...

In a single SSL site it´s works fine. However, if we have more than one SSL site in the same server, this plugin only check one of them, and all the sites has the same expiry date. Thanks.


One that works!
