How does SSL Certificate monitoring work?

Netumo will check SSL Certificates each time it connects to a particular site. If the certificate has any issue it will Fail the check and report an error.

In case that the certificate is expiring soon within the notification window as set up in the monitor then it will also trigger an alert.

How do I test Netumo and Notifications are working

The best way to rest Netumo is to create a page on your website. Include a unique term in such a page and then go to Netumo and add a monitor for that page that monitors that particular unique term.

Once Netumo checks the page you can then go to your page and change the term to be something else.

At this stage Netumo should send a NoMatch notification after detecting that there was a change and your unique term is no longer there.

This will ensure that Netumo is working correctly and Notifications are also triggering well.
