Name Data Type Permissions Description
src <String> Read-write Local path to and name of, or URL (protocol, host, path, and file name) for, the file in which to store the imported extension.
NOTE: The import fails if the object to be imported is on an HTTPS server that requires client certificate authentication for access, and the issuer certificate of the HTTPS server is not present in the specific path on NetScaler to authenticate the HTTPS server.
Minimum length = 1
Maximum length = 2047
name <String> Read-write Name to assign to the extension object on the Citrix ADC.
Minimum length = 1
Maximum length = 31
comment <String> Read-write Any comments to preserve information about the extension object.
Maximum length = 128
overwrite <Boolean> Read-write Overwrites the existing file.
trace <String> Read-write Enables tracing to the NS log file of extension execution:
off - turns off tracing (equivalent to unset ns extension <extension-name> -trace)
calls - traces extension function calls with arguments and function returns with the first return value
lines - traces the above plus line numbers for executed extension lines
all - traces the above plus local variables changed by executed extension lines
Note that the DEBUG log level must be enabled to see extension tracing.
This can be done by set audit syslogParams -loglevel ALL or -loglevel DEBUG.
Default value: off
Possible values = off, calls, lines, all
tracefunctions <String> Read-write Comma-separated list of extension functions to trace. By default, all extension functions are traced.
Maximum length = 256
tracevariables <String> Read-write Comma-separated list of variables (in traced extension functions) to trace. By default, all variables are traced.
Maximum length = 256
detail <String> Read-write Show detail for extension function.
Possible values = brief, all
type <String> Read-only .
Possible values = WSDL, CustomSettings, XMLSchema, XMLErrorPage, htmlpage, CustomResp, Extension, JSONErrorPage, ProtoFile, Signatures, Module
functionhits <Integer> Read-only Number of time function evaluates successfully.
functionundefhits <Integer> Read-only Number of times error occured in evaluating extension function.
functionhaltcount <Integer> Read-only Number of time function evaluation is halted.
_nextgenapiresource <String> Read-only .
__count <Double> Read-only count parameter

  • IMPORT

  • CHANGE
  • UPDATE
  • UNSET
  • GET (ALL)
  • GET
  • COUNT
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 red and placeholder content is marked in green
