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.
