Grafana dashboard: SSL Certificate Monitor
Description: OpenAdvices first published Dahsboard: Just one Table Widget to display the Certificate and Connection Status from HTTPS Connections that are Monitored with Prometheus.

Hi, i'm Malte from OpenAdvice and i referred to this Dashboard in my Grafana Blog post:

https://grafana.com/blog/2020/11/25/how-we-eliminated-service-outages-from-certificate-expired-by-setting-up-alerts-with-grafana-and-prometheus/"

Most Applications rely on connections to APIs, databases and maybe some authentication service. If those connection are monitored with the Prometheus Blackbox_exporter you also get the certificate status.

This Dashboard has only one panel to demonstrate how to display all connection metrics utilizing the new Grafana 7 table panel features.
