Monitoring Let’s Encrypt Certs

Recently, Let’s Encrypt announced they will be ending support for expiration notification emails by June 4, 2025. With this upcoming change, many are looking to alternate ways to monitor certificate expiration dates. At NodePing, we offer the capability to monitor your SSL certificates with our SSL check. Our SSL check lets you monitor certificate validity as well as notify you when your certificate is about to expire, that way you can make sure your certificate renewals are happening as you would expect, and fix it when it’s not.

Using the SSL Check

Our SSL check isn’t just limited to monitoring port 443 on your web server. You can also monitor non-website TLS services by using the URL port convention. For example, setting the target to “https://example.com:8000”. The check can be used to monitor SSL certs on services such as DoH, MQTT, Websockets, email, anything that accepts a TLS connection.

The most popular use for the SSL check is to monitor for an expiration date and alert the user at a defined number of days before expiration. However, the SSL check is also useful for diagnosing certificate chain errors. This can be useful to diagnose missing intermediary certificates or mismatched certificates in the SSL chain, for example.
