nodes for URLs at same location

Hi, I have an SSL certificate monitor up and running and it's working well for servers that have one URL. e.g. server x1.company.com has website w1.company.com .

what i need to do now is monitor several other URLs that are hosted on the one server.

e.g. server x1.company.com hosts w1.company.com, w2.company.com.au & w3.company.com.au. all at the same IP but all with different SSL certs

When i add an external node for w1.company.com it actually creates a node for x1.company.com with a dns of w1.company.com

Testing on this node fails as the URL isn't correct for the site

I can also not then add w2.company.com as an additional node.

Is there a way to create a node that only has the W1.company.com URL and doesn't tie up the IP address for other URLs?

I'll have a proper WMI node for the host itself to monitor the server.

Thanks

Ian

If you have enough polling engines, you can add each DNS name as a node on a different polling engine.

What I often do in this case is add one node for the actual server that hosts the URLS. I then add an app monitor (HTTP, HTTP, SSL certificate, etc.) for each URL hosted on that server. So you'd have a WMI node for your server, then several SSL certificate monitors:

w1.company.com

w2.company.com.au

w3.company.com.au

Hi, That sounds like a plan.

I have the server as a node and i have my SSL template but i can't seem to see how to make the template look at a specific URL.

I'm using the original template from SW as the basis to my template.

Any hints or screen grabs appreciated.

Thanks

Ian

Apologies for the oversight. Here is a custom application monitor template that will do what you need:

SSL Certificate Expiration with SNI for specified hostname

This app monitor will let you specify the host name for which you want to check the certificate. The monitor will hit the URL "https://(hostname you specified)" and compare that hostname with the FQDN in the certificate that comes back from the site. If they match, it has a status of OK/Up and it shows the number of days remaining on the certificate. If they don't match, it will have a status of Critical.

Many thanks to chad.every for creating the app monitor template "SSL Certificate Expiration with SNI", which was the basis for my template.

Thanks a lot for the link. Really appreciate it.

Now for the dumb questions.. ready? here we go.

1) where/how do i specify the URL that i want to test?
I can see the line in the script that has WebRequest -> $WebsiteDomain and that $WebsiteDomain -> $args[0] and it looks like the arg is node.dns which would work for a node that only has one url on it but what if the node hosts 10 urls?

2) as a solution for the above i'm guessing that i put the URL i want to test in the script arguments field.
Does that mean that i need to duplicate the template for each URL on my list?

3) lastly, once the template is assigned to the required node(s) would i trigger the alert is a similar way that my old check did?
e.g.

Thanks for your help and understanding for someone thats learning as I go.
