    Summary of Citrix NetScaler SDX discovery

    The ServiceNow Discovery application enables the automated discovery of Citrix NetScaler SDX devices using a specialized pattern. This capability helps populate the Configuration Management Database (CMDB) with accurate and detailed information about your Citrix NetScaler SDX infrastructure. The discovery process leverages a classification mechanism introduced in the Quebec release, which improves reliability by preventing entire probe failures when sub probes fail. The pattern triggers the Interactive Probe Shell over SSH for data collection.

    Prerequisites

    • Ensure that the CMDB CI Class Models and Discovery and Service Mapping Patterns applications are up to date.
    • Create SSH credentials with appropriate permissions for the Citrix NetScaler SDX devices.
    • Verify that the Discovery user has admin permissions and shell access on the device to run key commands such as show vmdevice and show hardware.
    • If admin permissions are unavailable, verify that the user can run read-only commands like show systemstatus and show hostname via the NetScaler CLI.

    Data Collected

    When running the Citrix NetScaler SDX pattern, Discovery collects and populates the following key CI attributes in the CMDB:

    • Citrix NetScaler SDX device (cmdbcicitrixnetscalersdx): name, serial number, IP address, CI identifier (object ID combining serial number and IP), description, and OS version.
    • Citrix NetScaler load balancer (cmdbcilbnetscaler): name, serial number, and IP address.

    CI Relationships and Visualization

    The discovery process establishes relationships between Citrix NetScaler SDX devices and registered Citrix NetScaler load balancers, supporting accurate dependency mapping. These relationships are visualized on the Dependency Views map, enabling you to see all discovered NetScaler SDX resources and their associations within your organization.

    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.​

    Prerequisites

    Verify that the following applications are up to date
    • CMDB CI Class Models
    • Discovery and Service Mapping Patterns
    • Visibility Content
    Create SSH credentials
    Create SSH credentials for the Citrix NetScaler SDX device. For more information, see .
    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.
    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.

    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:

    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.

    Data collected by Discovery during horizontal discovery

    Discovery populates the data in the CMDB when running the Citrix NetScaler SDX pattern.

    Table 1. Citrix NetScaler SDX [cmdb_ci_citrix_netscaler_sdx]
    Field Description
    Name [name] The name of the Citrix NetScaler SDX device.
    Serial number [serial_number] The serial number of the Citrix NetScaler SDX device.
    IP Address [ip_address] The IP address of the Citrix NetScaler SDX device.
    Object ID [object_id] The CI identifier of the Citrix NetScaler SDX device, which includes the serial_number and ip_address​.
    Description [short_description] The description of the Citrix NetScaler SDX device.
    OS Version [os_version] The version of the Citrix NetScaler SDX device.​
    Table 2. Citrix Netscaler [cmdb_ci_lb_netscaler]
    Field Description
    Name [name] The name of the Citrix NetScaler load balancer​.
    Serial number [serial_number] The serial number of the Citrix NetScaler load balancer.
    IP Address [ip_address] The IP address of the Citrix NetScaler load balancer​.

    On the Dependency Views map you can see all discovered Citrix NetScaler SDX resources in your organization, and the relationships between them.
