Secure Sockets Layer (SSL) is a standard security technology for establishing an encrypted link between a server and a client—typically a web server (website) and a browser, or a mail server and a mail client.

This integration will monitor your SSL certificates by collecting their expiration time.

Once enabled you will get a default SSL dashboard to help you get started monitoring your SSL certificates.

Metric Name Type Labels Unit Description
ssl.days_remaining Gauge ssl_cert_source day The SSL certificate remaining days for expiration.

Just run the SSL plugin against your hosts and it will start collecting metrics.
