Monitoring an HTTPS URL

[taandrews]

I haven't found any instructions for monitoring and SSL/HTTPS URL using Nagios XI 5.2.0. The site that I am trying to monitor ask to accept the cert before the page will load. Any suggestions?

Have you tried running the "Website" wizard?

On step 1 you provide the full address, for example: https://www.google.com

Yes I used the wizard and enter the URL, The wizard complete and generate a CRITICAL. When I hit the URL via the browser I am presented with the page that states "This Connection is Untrusted" and given the options "Get me out of here!" or "I Understand the Risks". Of course I can trust the site via the browser but the instructions nor the wizard provided a fix for this.

Can you post some screenshots of this please. I'm not sure if this is an issue with your XI server or the website you are trying to access.

Unfortunately I can not provide a screenshot.

I usually like to build up HTTP check commands using the command line.

Example: /usr/local/nagios/libexec/check_http -H <hostname.domanname> -u "/start/of/some/url" -S (for https), etc. etc.

That way the command can be tested quickly/easily on the fly, without having to propagate changes, apply-configs, etc.

For your case, my hunch is the -f (follow) argument may be helpful, but I am not certain. In my experience, SSL certs are tricky to work with in regards to monitoring.

Thanks @yo_marc, that would be the next troubleshooting steps we'll need to see, tests from the command line.
