    Summary of Citrix NetScaler SDX Discovery

    The ServiceNow Discovery application enables the detection of Citrix NetScaler SDX devices through a specific pattern. This functionality is available starting from the Quebec release and requires the latest Discovery and Service Mapping Patterns application from the ServiceNow Store for optimal performance. The new classification mechanism introduced in Quebec improves reliability by preventing entire probe failures when individual sub-probes encounter issues.

    Key Features

    • Classification Mechanism: Utilizes a triggerprobem2m table to manage probes associated with relevant protocols, triggering the Interactive Probe Shell via ssh.
    • Data Collection: During the discovery process, key information is captured and populated in the Configuration Management Database (CMDB), including device name, serial number, IP address, and OS version.
    • Dependency Views: Visual representation of all discovered Citrix NetScaler SDX resources and their interrelationships within your organization.

    Key Outcomes

    By implementing Citrix NetScaler SDX discovery, customers can expect:

    • Accurate inventory management of Citrix NetScaler SDX devices within the CMDB.
    • Improved operational efficiency through reliable data collection and visualization of device relationships.

    Prerequisites

    • Ensure the following applications are installed:
      • CMDB CI Class Models (version 1.0.20)
      • Discovery and Service Mapping Patterns (version 1.0.72)
    • Create SSH credentials for connecting to Citrix NetScaler SDX devices.
    • Verify the Discovery user has permissions to execute specific commands for data collection.

    The ServiceNow Discovery application can discover Citrix NetScaler SDX devices using the Citrix NetScaler SDX pattern. Discovering some of these resources requires updating the Discovery and Service Mapping Patterns application from the ServiceNow Store.

    You can use this pattern on the ServiceNow AI Platform® starting from the Quebec release.

    The new 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 new 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.​
