One of my responsabilities is the Certificates Control.
I want to control from Nagios when a certificate expires, the problem was that I didn't found one instruction for this. So I had to improvise.
At this post I explain how to configure one web page for each certificate in a same server for check the certificastes since Nagios with the command: "$USER1$/check_ssl_cert -H $HOSTADDRESS$ $ARG1$ $ARG2$"
WINDOWS
[ ] Connect to IIS
At this Server there are 3 Certificates
[ ] Create a new web pague
You can put something in this configuration
It is important the dates in blue box at this picture. In this example use a port 8003 you can use others ports frees.
I select the certificate number three.
If the IIS show this warning, no problem
The IIS result:
It's not necessary but I configure a simply default pague at new "web servers"
NAGIOS
You need the server to verificated existed.
At this screeshot you can view how to check 3 certificates at same server
In "Manage Hosts" I assign the server/s for to do a check.
If someone known a system better, please inform me ;-) Thanks.
