Let’s create a rule to notify us when any of the TLS certificates on sites we’re monitoring are close to expiring. Let’s check every 6 hours and send a notification every 12 hours.

Action typesedit
You can extend your rules by connecting them to actions that use the following supported built-in integrations. Actions are Kibana services or integrations with third-party systems that run as background tasks on the Kibana server when rule conditions are met.
You can configure action types on the Settings page.
