netscaler_servicegroup - Manage service group configuration in Netscaler
New in version 2.4.
Synopsis
- Manage service group configuration in Netscaler.
- This module is intended to run either on the ansible control node or a bastion (jumpserver) with access to the actual netscaler instance.
Requirements
The below requirements are needed on the host that executes this module.
- nitro python sdk
Parameters

|---|---|---|---|
| appflowlog |
| Enable logging of AppFlow information for the specified service group. | |
| autoscale |

| cachetype |
| Cache type supported by the cache server. | |
| cip |
| Insert the Client IP header in requests forwarded to the service. | |
| cipheader | Name of the HTTP header whose value must be set to the IP address of the client. Used with the Client IP parameter. If client IP insertion is enabled, and the client IP header is not specified, the value of Client IP Header parameter or the value set by the set ns config command is used as client's IP header name. Minimum length = 1 | ||

| monitorname | The monitor name to bind to this servicegroup. | ||
| weight | Weight to assign to the binding between the monitor and servicegroup. | ||
| monthreshold | Minimum sum of weights of the monitors that are bound to this service. Used to determine whether to mark a service as UP or DOWN. Minimum value = 0
Maximum value = 65535
| ||
| netprofile | Network profile for the service group. Minimum length = 1 Maximum length = 127 | ||
| nitro_pass required | The password with which to authenticate to the netscaler node. | ||
| nitro_protocol |
| Which protocol to use when accessing the nitro API objects. | |
| nitro_timeout | Default: 310 | Time in seconds until a timeout error is thrown when establishing a new session with Netscaler | |
| nitro_user required | The username with which to authenticate to the netscaler node. | ||
| nsip required | The ip address of the netscaler appliance where the nitro API calls will be made. The port can be specified with the colon (:). E.g. 192.168.1.1:555. | ||
| pathmonitor | Path monitoring for clustering. | ||
| pathmonitorindv | Individual Path monitoring decisions. | ||
| rtspsessionidremap |
| Enable RTSP session ID mapping for the service group. | |
| save_config |
| If true the module will save the configuration on the netscaler node if it makes any changes. The module will not save the configuration on the netscaler node if it made no changes. | |
| servicegroupname | Name of the service group. Must begin with an ASCII alphabetic or underscore _ character, and must contain only ASCII alphanumeric, underscore _, hash #, period ., space , colon :, at @, equals =, and hyphen - characters. Can be changed after the name is created.Minimum length = 1 | ||
| servicemembers | A list of dictionaries describing each service member of the service group. | ||
| weight | Weight to assign to the servers in the service group. Specifies the capacity of the servers relative to the other servers in the load balancing configuration. The higher the weight, the higher the percentage of requests sent to the service. Minimum value = 1
Maximum value = 100
| ||
| ip | IP address of the service. Must not overlap with an existing server entity defined by name. | ||
| servername | Name of the server to which to bind the service group. The server must already be configured as a named server. Minimum length = 1 | ||
| state |
| Initial state of the service after binding. | |
| customserverid | The identifier for this IP:Port pair. Used when the persistency type is set to Custom Server ID. | ||
| hashid | The hash identifier for the service. This must be unique for each service. This parameter is used by hash based load balancing methods. Minimum value = 1
| ||
| serverid | The identifier for the service. This is used when the persistency type is set to Custom Server ID. | ||

Maximum value = 31536000
| ||
| tcpb |
| Enable TCP buffering for the service group. | |
| tcpprofilename | Name of the TCP profile that contains TCP configuration settings for the service group. Minimum length = 1 Maximum length = 127 | ||
| useproxyport |
| Use the proxy port as the source port when initiating connections with the server. With the NO setting, the client-side connection port is used as the source port for the server-side connection. Note: This parameter is available only when the Use Source IP usip parameter is set to yes. | |
| usip | Use client's IP address as the source IP address when initiating connection to the server. With the NO setting, which is the default, a mapped IP (MIP) address or subnet IP (SNIP) address is used as the source IP address to initiate server side connections. | ||
| validate_certs | Default: yes | If no, SSL certificates will not be validated. This should only be used on personally controlled sites using self-signed certificates. | |
