+Notify on host up and down
+==========================
+
+[◀ Go back to main README](../README.md)
+
+Description
+-----------
+
+This script sends notifications about host UP and DOWN events. In comparison
+to just netwatch (`/ tool netwatch`) and its `up-script` and `down-script`
+this script implements a simple state machine. Host down events are triggered
+only if the host is down for several checks to avoid false alerts.
+
+Requirements and installation
+-----------------------------
+
+Just install the script:
+
+    $ScriptInstallUpdate netwatch-notify;
+
+Then add a scheduler to run it periodically:
+
+    / system scheduler add interval=1m name=netwatch-notify on-event="/ system script run netwatch-notify;" start-time=startup;
+
+Configuration
+-------------
+
+The hosts to be checked have to be added to netwatch with specific comment:
+
+    / tool netwatch add comment="notify, hostname=example.com" host=[ :resolve "example.com" ] timeout=5s;
+
+Also notification settings are required for e-mail and telegram.
