Discovery Scans

Create a list of networks for device discovery. You can add a network by CIDR, IP range, Network or import from CSV. You can enable different discovery scans to be performed on each network and specify which deployment representative performs the scan, known as the Scanner.

Credentials must be setup in Active Discovery Settings before SNMP and Remote Inventory can be performed.

The option to Download Agent is available if you want to install further agents on devices. The Download the Agent dialog appears, click Download to confirm the action. The Neurons Agent and the Infrastructure Agent Policy, which includes the Discovery capabilities enabled by default, is downloaded.

To use a custom Agent Policy you must enable the Discovery capabilities. Learn more about Agent Policy Capabilities.

To Add a network

Setup the IP range that a discovered device must fall within to be scanned, select the scan types and configure a scanning schedule.

  1. Click Add. The Add IP Range panel displays.
  2. Enter the Name of the network.
  3. Select the Format of the IP range:
    • CIDR: Enter the CIDR Block. For example;
    • Range: Enter the first and last IP in the range. For example; -
    • Network: Enter the Network Address and select the Subnet Mask. For example;,
  4. Select the Scan Types that can be performed on the network:
    • Active: Select to enable Active scanning on the network.
      • OS Detection: If Active scan is enabled, select to turn on OS Detection.
    • Remote Inventory: Select to enable remote inventory scanning on the network.
    • SNMP: Select to enable SNMP scanning on the network.
  5. Select the Scanner from the drop-down list. This is the agent endpoint with the Active Discovery capability enabled, that you want to use as the scanner to perform discovery scans, within the specified IP range. The default is Elected Scanner, which is the first agent endpoint that polled in. The name of the currently elected scanner is displayed below. If there is no scanner elected, or it is offline the text displays 'waiting for a scanner to be elected'.
    This option is available for organizations that may have separate sites, or segregated networks, where one agent endpoint will not reach all areas of the network.
  6. Select Enabled to enable an automatic scanning schedule.
    • Date: Select the date and time from the calendar to schedule when the first scan will start. Click OK.
      If the date/time is set in the past, the scan will start immediately.
    • Repeat: Select to set a schedule frequency. Specify the time period between repeating the scans using the fields; number (1-99) and unit (Minutes, Hours, Days, Weeks). For example, number = 30 unit= Minute(s), this means the scan is scheduled to run every 30 minutes.
      If a scan runs past the next scheduled time, it will run to completion, and then run at next scheduled repeat interval. The schedule runs indefinitely.
  7. If you want to schedule the scan types differently for a network range, create a new network entry for each scan type and set the schedule accordingly.

  1. Click Save. The network is added to the table.

To Import a network

Download a template, save as CSV and Import the IP range data for the networks to add to the table.

  1. Select Import. The Import IP Ranges panel displays.
  2. To import your data you can either download a template to ensure the data is in the correct format; name and CIDR, or you can select, or drag and drop, a file to upload.
  3. The IP's are validated on import. Do not leave empty rows. Valid entries are highlighted in green, any invalid or duplicate entries will be highlighted in red. You cannot proceed until any invalid entries are corrected within the CSV file.
  4. Click Confirm. The networks are added to the table.


The following Actions can apply to multiple selected networks, to include a network in the action, click the check box in the first column. To apply an Action to only one network, select the ellipsis ellipsis icon.

  • Start: Click to send a scan start request to the agent. The types of scans that will be performed are listed in the Scan Types column. To amend the scan types, Edit the network range.
    The last scans performed can be seen in Devices > Device Details > Data Sources. The Discovery scans are: IvantiActiveEngine, IvantiSnmpEngine, IvantiRemoteinventoryEngine and IvantiOsEngine.
    The status of the scans is reported in the Status column:
    • Blank: A scan has never been run.
    • Start requested: A start scan has been requested.
    • Queued: The agent has received a start request: either manually by a user, or automatically by a schedule.
    • In progress: The scan has started and is in progress.
    • Stop Requested: A user has requested to stop any scans that are in progress.
    • Stopping: The agent has received a stop request.
    • Stopped: The scan has stopped.
    • Completed: The scan completed.
    • Scan Status not supported: The version of the agentless engine does not support reporting on scan status. The version must be 1.0.859.0 or later, agents should update automatically.

    Hover over the Status progress bar to display a tooltip with further details, such as the scan types, scan duration, number of target IPs in the network, and how the scans were initiated; either by a schedule or manually, and the time (local timezone to the device you are on) the first scan was started.

    If the scan is running on a schedule, the schedule frequency displays in the Schedule column. If the column is blank there is no schedule set.

  • Stop: Click to stop the scan.
  • Edit: Click to edit the network name, IP range, selected scan types, and run schedule.

    When you multi-select items to edit, if there are a mixture of enabled and disabled features such as; scan types or schedules, the check box displays checkbox with blue background and white dash symbol. If all features for the selected items are enabled, the check box displays check box with blue background and white tick. If the check box is blank, all features are disabled.

  • Delete: Click to delete the network.

Customize Grid: Opens the Column Chooser, select which columns to display. You can also change the order of columns in the table.

Reset Grid: Return the table to the original format.
