Citrix NetScaler SDX discovery

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

Visit the ServiceNow Store 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.

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 SSH credentials.

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.
