## Summary of Citrix NetScaler SDX discovery

The ServiceNow Discovery application enables automated discovery of Citrix NetScaler SDX devices using the dedicated Citrix NetScaler SDX pattern.
This discovery process leverages a classification mechanism introduced in the Quebec release, which enhances reliability by isolating failures within multi-probe operations.
To ensure accurate discovery, customers may need to update the Discovery and Service Mapping Patterns application from the ServiceNow Store.

## Prerequisites

* Ensure that key applications such as CMDB CI Class Models, Discovery and Service Mapping Patterns, and Visibility Content are up to date.
* Create SSH credentials specifically for accessing Citrix NetScaler SDX devices.
* Verify that the Discovery user has administrative permissions and shell access to execute critical commands including `show vmdevice` and `show hardware`. If full permissions are not available, read-only commands like `show systemstatus` and `show hostname` must be accessible to gather essential data.

## Data Collection and CMDB Integration

During discovery, the application populates the Configuration Management Database (CMDB) with detailed information about Citrix NetScaler SDX devices and associated NetScaler load balancers. Key attributes collected for the Citrix NetScaler SDX include:

* Name
* Serial number
* IP address
* Object ID (combining serial number and IP)
* Description
* OS version

Similarly, for Citrix NetScaler load balancers, the name, serial number, and IP address are recorded.

## CI Relationships and Dependency Mapping

The discovery process establishes relationships between the Citrix NetScaler SDX devices and their associated NetScaler load balancers within the CMDB. On the Dependency Views map, customers can visualize all discovered Citrix NetScaler SDX resources and their interdependencies, aiding in comprehensive infrastructure management and impact analysis.  
The ServiceNow Discovery application can discover Citrix NetScaler SDX devices using the Citrix NetScaler SDX pattern. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.
The classification mechanism introduced in Quebec triggers the pattern. The classification mechanism prevents the whole probe from failing if a sub probe in a multi-probe fails.​

The classification mechanism includes a trigger_probe_m2m table, which defines which classification probe to trigger in relation to the relevant protocol. For this pattern, it triggers the Interactive Probe Shell over the
ssh protocol.​

## Request apps on the Store {#citrix-netscaler-sdx-discovery__section_ltl_dsh_2nb}

Visit the [ServiceNow Store](https://store.servicenow.com/sn_appstore_store.do#!/store/home) website to view all the available apps and for information about submitting requests to the store. For cumulative release notes information for all released apps, see the [ServiceNow Store version history release notes](https://www.servicenow.com/docs/r/store-release-notes/sn-store-release-notes.html).{#citrix-netscaler-sdx-discovery__inline-send-to-store}

## Prerequisites {#citrix-netscaler-sdx-discovery__section_f1x_tnw_24b}

Verify that the following applications are up to date
:
    * CMDB CI Class Models
    * Discovery and Service Mapping Patterns
    * Visibility Content
    {#citrix-netscaler-sdx-discovery__ul_ox1_jyj_rfc}

Create SSH credentials
:   Create SSH credentials for the Citrix NetScaler SDX device. For more information, see [SSH credentials](https://www.servicenow.com/docs/access?context=r_SSHCredentialsForm&version=yokohama&pubname=yokohama-platform-security&ft:locale=en-US).

Verify permissions for the following commands
:   Verify that the Discovery user has admin permissions and can run the following commands. The show hardware command requires shell access as well.  
    {#citrix-netscaler-sdx-discovery__table_h4p_1p3_2nb__entry__2}

    | Command | Description |
    |-|-|
    | show vmdevice | Get virtual machine (VM) instances. |
    | show hardware | Provides a quick overview of all configurable settings for the Citrix NetScaler SDX devices. |
    [ ]

    {#citrix-netscaler-sdx-discovery__table_h4p_1p3_2nb}

:   If the Discovery user doesn't have shell access or admin permissions, verify that the user can run the following read-only commands in the NetScaler CLI instead:

    {#citrix-netscaler-sdx-discovery__table_readonly_netscaler_cli__entry__2}

    | Command | Description |
    |-|-|
    | show systemstatus | Retrieve the current system status of the SDX appliance, including serial number, build number, and product name. |
    | show hostname | Retrieve the hostname of the SDX appliance. |
    [ ]
