Node Group attributes
This article describes the setup of the Node Groups in mode detail. For a general description refer to the 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.
