 The configuration is at the end layer quite simple you have a "check" and a "host" and you connect them with a service. Like I show at the bottom line in the diagram above. Whats makes this a tad more complicated is that you can inherit things from a "parent" definition. Which is what I show with arrows (bottom to top) above. The templates with dashed lines are the base templates which all services and hosts inherit.

+=== 5.2 Passive Checks ===
+The main difference between passive checks and active checks are the following two flags:
+ '''active_checks_enabled'''::
+   Active service checks are enabled
+ '''passive_checks_enabled'''::
+   Passive service checks are enabled/accepted
+So adding the following will "change" an active check to a passive check.
+{{{
+        active_checks_enabled   0 ; Active service checks are enabled
+        passive_checks_enabled  1 ; Passive service checks are enabled/accepted
+}}}
+So you say what shall I enter for command for my passive checks?
+
+There are several options for this depending on what you want I wont (as always) go into the details in this quick guide but the short of it is either you use check_dummy or you use the actual command and setup freshness checks. With freshness checks active it means that if a result is not submitted Nagios will actively go out and seek the information (this is what I would recommend for host checks at least).

 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.

 The following service will monitor the CPU load on the remote host. The "alias_cpu" argument which is passed to the check_nrpe command definition tells NSClient++ to run the "alias_cpu" command as defined in the alias section of the NSC.ini file.
