Having the Xymon server validate the intermediate certificates won't help if they're missing off the server that owns the certificate. The Xymon server would have the certs installed and always get a match.

Where are the intermediate certs missing? Does the web server even start properly if it can't validate its own cert?

As you know newer browsers doesn't have problem but the older one show cert error when the intermediate cert missing. We have bunch of cert so some time engineers forget to install the intermediate cert and caused issue.

What was the exact problem with the intermediate certificate? What should be monitored? Maybe we can come up with a way to add additional monitoring parameters to Xymon's SSL monitoring if we know exactly what should be monitored.

My first guess is expiration, but I'm not sure if you can sign a cert if it expires after your intermediate is due to expire. The only other thought is if the chain was incomplete...
