+===== Node Group attributes =====
+This article describes the setup of the Node Groups in mode detail. For a general description refer to the [[menu:inventory:node_groups:node_groups|Node groups]] article.
+Node groups are used throughout NetYCE as a dynamic means to use groups of nodes. Dynamic, because the group definition contains rules and conditions to find nodes based on attribute values.
+NetYCE has two distinct type of nodes: 'yce'-nodes are fully modeled and consist of many different object types offering a massive set of variables. 'cmdb'-nodes are not modeled as offer only a handful of variables but can be added very quickly ad-hoc. Most customers use a combination of these types of nodes.
+When creating node-groups using the various node variables as dynamic filter, we have to make the same distinction between 'yce' and 'cmdb' nodes. Hence there are three "scopes" of node-groups: The 'all' scope will find nodes in both the 'yce' and the 'cmdb' realms using the attributes that are common to both.
+Then there is the 'cmdb' scope that locates nodes in the 'cmdb' using its set of attributes. And finally the 'yce' scope which locates its nodes from the 'yce' database.
+The 'attributes available to a node-group are thus dependent on the scope selected when creating the group. Due to its restriction in usable attributes an 'all' scope node-group can be changed into an 'yce' or 'cmdb' scope, but not the reverse.
+'All' atributes:
+^Attribute^Notes^
+| Hostname | The unique name of the node |
+| Node_fqdn| The full-qualified-domain-name of the node |
+| Domain | The management domain name the node belongs to |
+| Region | The name of the Region of the Client the node belongs to |
+| Client_type | The client-type of the node's Client |
+| ClientCode | The name of the node's Client |
+| SiteCode | The name of the node's Site |
+| Vendor_type | The name of the node's vendor module |
+| Node_model | The hardware type as reported by the node. Updated with job or nccm. |
+| Software_version | The firmware version as reported by the node. Updated with job or nccm. |
+| Device_status | The textual status of node ('active', 'planned', etc) |
+| DeviceStatus | The numeric status of node (0, 1, 2, etc) |
+| Source | 'yce' or 'cmdb', 'yce' prevails over 'cmdb' |
+'Cmdb' attributes:
+^Attribute^Notes^
+|  includes the 'all' attributes  ||
+| Admin_domain | The name of the organizational group responsible for the node |
+| Mgmt_vrf_name | The name of the management VRF that is to be used for (backup) file transfers |
+'Yce' attributes:
+^Attribute^Notes^
+|  includes the 'all' attributes  ||
+| Node_domain | The domain-name part of node's fqdn |
+| Node_position | The location of the node in the service reference model (NA, NB, SA, SB, SV) |
+| Template| The name of the node's main template |
+| Node_class | The name of the node-type class or group |
+| Node_type | The name of modeled node-type that created the node |
+| Site_type | The name of the site's type |
+| Service_class | The name of the service-class the service-type is part of |
+| Service_type | The name of the service-type model the node was created with |
+| Model_name |The hardware model name as assigned to the template |
+The 'Value' holds a list of (wildcard) strings that each can match with the 'Attribute'.
+When matching to a string containing spaces, use quotes around the string.
