Unless you're using an automated method of obtaining TLS certificates for your IT devices, then you need to manage and monitor them

And the reason for that is because a certificate will have an expiry date, or at least it should if you're concerned about security

So you need to be proactive and replace certificates before they expire, otherwise a browser will either complain when a certificate expires and so will the users or worse still a browser will refuse to connect to a device

Now an interesting open source combination of monitoring tools that's available for free is Prometheus and Grafana

So in this video, we show how to configure Prometheus and Grafana to monitor TLS certificates, when you're using Docker
