+@title = "monitor"
+@summary = "Nagios monitoring and continuous testing."
+
+The `monitor` node provides a nagios control panel that will give you a view into the health and status of all the servers and all the services. It will also spam you with alerts if something goes down.
+
+Topology
+--------------------------------------
+
+Currently, you can have zero or one `monitor` nodes defined. It is required that the monitor be on the webapp node. It was not designed to be run as a separate node service.
+
+Configuration
+-----------------------------------------------
+
+* `nagios.environments`: By default, the monitor node will monitor all servers in all environments. You can optionally restrict the environments to the ones you specify.
+
+For example:
+
+    {
+      "nagios": {
+        "environments": ["unstable", "production"]
+      }
+    }
+
+Access nagios web
+-----------------------------------------------
+
+*Determine the nagios URL*
+
+    $ leap ls --print domain.name,webapp.domain,ip_address monitor
+    > chameleon  chameleon.bitmask.net, demo.bitmask.net, 199.119.112.10
+
+In this case, you would open `https://demo.bitmask.net/cgi-bin/nagios3` in your browser (or alternately you could use 199.119.112.10 or chameleon.bitmask.net).
+
+*Determine the nagios password*
+
+The username for nagios is always `nagiosadmin`. The password is randomly generated and stored in `secrets.json` under the key `nagios_admin_password`. Note that the login is `nagiosadmin` without underscore, but the entry in secrets.json is with underscores.
