+    notification_description: |
+      The [Alerta](https://alerta.io/) monitoring system is a tool used to consolidate and de-duplicate alerts from multiple sources for quick ‘at-a-glance’ visualization. With just one system you can monitor alerts from many other monitoring tools on a single screen.
+      You can send Netdata alerts to Alerta to see alerts coming from many Netdata hosts or also from a multi-host Netdata configuration.

+              You will need an API key to send messages from any source, if Alerta is configured to use authentication (recommended). To create a new API key:
+              1. Go to Configuration > API Keys.
+              2. Create a new API key called "netdata" with `write:alerts` permission.
