Currently in the production environment, access to most business systems has been adjusted to HTTPS. The certificates we use have time limits. For example, they expire once every three months. So what will be the impact if the certificate expires? For websites, the expiration of SSL certificates will not only cause the browser to issue an "insecure" warning, but will also affect the normal display of website pages, making users unable to browse normally, affecting the user's browsing experience.Especially for websites that involve financial transactions, they are undoubtedly the targets of many criminals. If the SSL certificate expires and is not renewed in time, it may give criminals an opportunity to take advantage of it and cause property losses to users.The certificate function is so important. As operation and maintenance personnel, faced with a large number of SSL certificates, it is very difficult to remember the expiration time of each certificate. Therefore, how to monitor the status of each certificate is one of the key issues for operation and maintenance personnel.
Tingyun can provide page monitoring functions, using SaaS Probes pre-deployed in more than 800 cities and operators around the world, to simulate real users and proactively monitor customer pages.Turn on the certificate monitoring function in the task configuration. When the Probe accesses the customer page, after the connection is successfully established, the certificate's issuing authority name, time and other indicators are verified during the handshake. If there is a certificate error, the corresponding error can be thrown, and the detailed information can be displayed in the log information.
By simulating users to actively dial and test, certificate error problems can be discovered proactively and resolved in advance to reduce the impact on users.
