 Depending on which directory your plugins are installed into you may need to
 update the global `PluginDir` constant in your [Icinga 2 configuration](4-configuring-icinga-2.md#constants-conf).
 This constant is used by the check command definitions contained in the Icinga Template Library
 to determine where to find the plugin binaries.
