Currently in production environments, access to most business systems has been adjusted to HTTPS. Our used certificates all have time limits, for example, expiring once every 3 months. So what impact will it have if certificates expire? For websites, SSL certificate expiration will not only cause browser "Not Secure" warnings but also affect normal display of website pages. Users cannot browse normally, affecting user browsing experience.Especially for websites involving financial transactions, they are undoubtedly targets of many criminals. If SSL certificates expire and are not renewed in time, it may give criminals an opportunity, causing user property losses.Certificate function is so important. As operations personnel, facing massive SSL certificates, remembering the expiration time of each certificate is very difficult. So how to monitor the status of each certificate is one of the key concerns of operations personnel.
TingYun can provide page monitoring functionality, using SaaS Probes pre-deployed in over 800 cities and ISPs globally to simulate real users and actively monitor customer pages.Turn on the certificate monitoring function in task configuration. When nodes access customer pages, after connection establishment is successful, verify certificate issuer name, time, and other metrics during handshake. If there are certificate errors, corresponding errors will be thrown, and detailed information can be displayed in log information.
Through simulating user active synthetic monitoring, proactively discover certificate error problems, resolve them in advance, and reduce impact on users.
