NameData TypePermissionsDescription
name<String>Read-writeName of the nodegroup. The name uniquely identifies the nodegroup on the cluster.
Minimum length = 1
strict<String>Read-writeSpecifies whether cluster nodes, that are not part of the nodegroup, will be used as backup for the nodegroup.
* Enabled - When one of the nodes goes down, no other cluster node is picked up to replace it. When the node comes up, it will continue being part of the nodegroup.
* Disabled - When one of the nodes goes down, a non-nodegroup cluster node is picked up and acts as part of the nodegroup. When the original node of the nodegroup comes up, the backup node will be replaced.
Default value: NO
Possible values = YES, NO
sticky<String>Read-writeOnly one node can be bound to nodegroup with this option enabled. It specifies whether to prempt the traffic for the entities bound to nodegroup when owner node goes down and rejoins the cluster.
* Enabled - When owner node goes down, backup node will become the owner node and takes the traffic for the entities bound to the nodegroup. When bound node rejoins the cluster, traffic for the entities bound to nodegroup will not be steered back to this bound node. Current owner will have the ownership till it goes down.
* Disabled - When one of the nodes goes down, a non-nodegroup cluster node is picked up and acts as part of the nodegroup. When the original node of the nodegroup comes up, the backup node will be replaced.
Default value: NO
Possible values = YES, NO
state<String>Read-writeState of the nodegroup. All the nodes binding to this nodegroup must have the same state. ACTIVE/SPARE/PASSIVE.
Possible values = ACTIVE, SPARE, PASSIVE
priority<Double>Read-writePriority of Nodegroup. This priority is used for all the nodes bound to the nodegroup for Nodegroup selection.
Minimum value = 0
Maximum value = 31
currentnodemask<Double>Read-onlyBitmap of current nodes in this nodegroup.
backupnodemask<Double>Read-onlyBitmap of backup nodes in this nodegroup.
boundedentitiescntfrompe<Double>Read-onlyCount of bounded entities to this nodegroup accoding to PE.
activelist<Double[]>Read-onlyActive node list of this nodegroup.
backuplist<Double[]>Read-onlyBackup node list of this nodegroup.
__count<Double>Read-onlycount parameter

Some options that you can use for each operations:

  • Getting warnings in response:NITRO allows you to get warnings in an operation by specifying the "warning" query parameter as "yes". For example, to get warnings while connecting to the NetScaler appliance, the URL is as follows:

    http://<netscaler-ip-address>/nitro/v1/config/login?warning=yes

    If any, the warnings are displayed in the response payload with the HTTP code "209 X-NITRO-WARNING".

  • Authenticated access for individual NITRO operations:NITRO allows you to logon to the NetScaler appliance to perform individual operations. You can use this option instead of creating a NITRO session (using the login object) and then using that session to perform all operations,

    To do this, you must specify the username and password in the request header of the NITRO request as follows:

    X-NITRO-USER:<username>

    X-NITRO-PASS:<password>

    Note:In such cases, make sure that the request header DOES not include the following:

    Cookie:NITRO_AUTH_TOKEN=<tokenvalue>

Note:

Mandatory parameters are marked in redand placeholder content is marked in <green>.
