+=== 7.0 Introduction ===
+[[Image(wiki:doc/usage/nagios/nrpe:nagios-configuration-inheritance.png)]]
+
+Nagios configuration is in itself a whole chapter and this is just a quick peek on how you can do things. First off there are a few concepts to understand:
+ * templates are the same as the corresponding item but they have a flag register = 0 which makes them "unlistable items"
+ * services are essentially checks (is check CPU)
+ * hosts are essentially computers
+ * groups are an important concept which I ignore here for simplicity (I recommend you use it)
+
 === 7.1 Template ===
 First, its best practice to create a new template for each different type of host you'll be monitoring. Let's create a new template for windows servers.
 {{{
 define host{
-        name                                    tpl-windows-servers ; Name of this template
-        use                                             generic-host ; Inherit default values
-        check_period                    24x7
-        check_interval                  5
-        retry_interval                  1
-        max_check_attempts              10
-        check_command                   check-host-alive
-        notification_period             24x7
+        name                    tpl-windows-servers ; Name of this template
+        use                     generic-host ; Inherit default values
+        check_period            24x7

+        notification_period     24x7
         notification_interval   30
         notification_options    d,r
-        contact_groups                  admins
-        register                                0 ; DONT REGISTER THIS - ITS A TEMPLATE
+        contact_groups          admins
