.SYNOPSIS
This is the primary function of the module, and provides a cmdlet interface to manage configuration jobs,
templates, inventory, and other system settings related to both ADMs and the ADCs they manage.
.DESCRIPTION
This function provides a cmdlet wrapper for what results in a 'well-formed' Invoke-RestMethod command which
includes the required formatting for ADM and ADC Nitro API calls. In addition to direct API calls to the ADM host,
the
.PARAMETER ADMSession
An existing custom ADM Neb Request Session object returned by Connect-ADM
.PARAMETER OperationMethod
Specifies the method used for the web request
.PARAMETER ResourceType
Type of the NS appliance resource
.PARAMETER ResourceName
Name of the NS appliance resource, optional
.PARAMETER Action
Name of the action to perform on the NS appliance resource
.PARAMETER Payload
Payload 0f the web request, in hashtable format
.PARAMETER Getwarning
Switch parameter, when turned on, warning message will be sent in 'message' field and 'NARNING' value is set in severity
field of the response in case there is a warning. Turned off by default.
.PARAMETER OnErrorAction
Use this parameter to set the onerror status for nitro request. Applicable only for bulk requests.
Acceptable values: "EXIT", "CONTINUE", "ROLLBACK", default to "EXIT"
.PARAMETER ADCHost
This parameter specifies an ADC host name or IP address to proxy API calls to. Because ADM is responsible for the API proxy
calls, the device profile bound to the instance defines the level of entitlement to the target ADC. In other words, if
your device profile uses nsroot, you can do anything you want, but if it uses a read-only account all API proxy calls
will be limited to the command policy bound to the ADC system user or group.
.EXAMPLE
Get all ADC's in inventory.
Invoke-ADMNitro -ADMSession $Session -OperationMethod POST -ResourceType ns -Payload $payload
.OUTPUTS
Only when the OperationMethod is GET:
PSCustomObject that represents the JSON response content. This object can be manipulated using the ConvertTo-Json Cmdlet.
