    • Define Operational Technology (OT) discovery schedules that orchestrate how and when the Discovery for an OT function should run. You can also perform an immediate Quick Discovery or an actual OT Discovery run.

    Before you begin

    Do the following actions before you run IT Discovery for OT Networks:

    Role required: ot_discovery_admin

    Procedure

    1. Navigate to All > OT Discovery > OT Discovery Schedules.
    2. Run Quick Discovery, or select or create an OT discovery schedule.
      TaskDescription
      Run an immediate Quick Discovery Click Quick Discovery and do the following actions:
      1. In the Target IP field, enter the IP address in which the Discovery for the OT process should run.
      2. In the MID Server field, select the MID Server in which the Discovery process should run.
      3. Click OK.
      Select or create an OT discover schedule
      1. Select an existing OT discovery schedule or click New to create a new one.
      2. Perform the steps that follow to create the OT discovery schedule record in the OT Discovery Schedule form.
    3. In the form, fill in the OT Discovery Schedule fields.
      FieldDescription
      Name Unique, descriptive name for your OT discovery schedule.
      Discover Scan type for the OT discovery schedule.
      Configuration items
      Uses Discovery identifiers to match devices with configuration items (CIs) in the CMDB and to update the CMDB. Perform a simple discovery by selecting a specific MID Server to scan for all protocols (SSH, WMI, and SNMP) or perform advanced discoveries with discovery behaviors. When you select a behavior, the MID Server field is not available.
      IP addresses
      Scans devices without the use of credentials. These scans discover all the active IP addresses in the specified range and create device history records, but do not update the CMDB. IP address scans also show multiple IP addresses that are running on a single device. Identify devices by class and by type, such as Windows computers and Cisco network gear.
      Default Purdue level Purdue level that you want the OT discovery schedule to run in, or select --None-- for all Purdue levels.

      Most of the fields on this form are identical to or operate in the same manner as the standard Discovery form. Only those fields that differ from the standard Discovery scheduling appear in this topic. To learn more about the remaining fields, see Schedule a horizontal discovery
    4. Run the Discovery process right away, or save the OT discovery schedule to run at the times you designated in the record.
      TaskDescription
      Run Discovery immediately Click the Discover now related link.
      Run Discovery at the time designated in the OT discovery schedule Click Update.

    Result

    When the IT Discovery for OT Networks process runs, it creates a history record in the Discovery Status related list.
