    • The ServiceNow Discovery application uses the Next-Generation Palo Alto Firewall pattern to find Palo Alto Networks firewalls. 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 discovery pattern uses a set of SNMP calls to find the Palo Alto Networks firewalls. Discovery uses the pattern to run horizontal discovery.

    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

    • Ensure that your network firewall device has SNMP access.
    • On the ServiceNow instance, configure SNMP credentials. For more information, see SNMP credentials.
    • Add the SNMP system OID record for the Palo Alto Networks device to the ServiceNow instance. Update the following:
      • Classifier: Palo Alto Firewall
      • Class: Palo Alto Firewall Device
    • Deploy the pattern as follows:
      1. Download and install Firewall extension classes from the ServiceNow Store. The app adds the new CMDB classes required for network firewall discovery.
      2. Download and install the discovery pattern from the ServiceNow Store.
      3. Sync the pattern with the appropriate MID Server.

    Data collected by Discovery during horizontal discovery

    Discovery populates the data in the CMDB when running the Next-Generation Palo Alto Firewall Pattern.
